Advantages of the invention

The products of the operation of the internal combustion engine includes a fuel and exhaust gases in addition to the torque and the sum of these products determines various characteristics of the internal combustion engine. According to the first aspect of the present invention requirements associated with different characteristics of the internal combustion engine, are expressed in physical units of torque, the efficiency or the composition of the mixture air-to-fuel". Torque, efficiency and composition of the mixture air-fuel are three main factors that determine the results of the internal combustion engine. Therefore, the use of these physical quantities in order to represent the requirements associated with different characteristics, and calculate control variables actuators based on the requirements in CR is shining moment, the meaning of effectiveness and value requirements in the composition of the mixture air-fuel obtained by matching the above requirements, ensures the proper administration of the actuators so that the requirements are included in the results of the internal combustion engine.

According to the second aspect of the invention, the requirements associated with responsiveness, exhaust gases and fuel consumption, which are elements of the characteristics of the internal combustion engine, can easily be achieved. Requirements related to responsiveness, can be expressed, for example, in terms of torque or efficiency. Requirements associated with the exhaust gases, can be expressed, for example, in terms of efficiency or the composition of the mixture air-to-fuel". Requirements related to fuel consumption, can also be expressed, for example, in terms of efficiency or the composition of the mixture air-to-fuel".

According to a third aspect of the invention, the requirements associated with each characteristic of the internal combustion engine, can easily be achieved by controlling the amount of intake air, the ignition timing and the amount of fuel injection. The amount of intake air can be calculated from the value of requirements in torque and values requirements in effect is aktivnosti. The ignition timing can be calculated from the value of requirements in torque. The amount of fuel injection can be calculated from the value of the requirements in the composition of the mixture air-to-fuel". These three values requirements, however, are only part of the information used to calculate control variables, and, thus, information on operating parameters and operating States of the internal combustion engine, such as the estimated value of the torque or the rotational speed of the engine, may be used instead of the above three values, requirements or be combined with them.

According to a fourth aspect of the invention, at least one of the three values of requirements, namely the request torque, the value requirements of efficiency and value requirements in the composition of the mixture air-to-fuel", is modified so as to have a dependency that ensures proper operation of the internal combustion engine, and control variables on the basis of modified values requirements are assigned to each actuator.

The first variant of the invention, the

The first variant of implementation of the present invention is described below with reference to the drawings. Describes the first version of the implementation of the present invention, in which the control device of the present invention is applied to an internal combustion engine with spark ignition (hereinafter called "engine"). However, the present invention is applicable to any engine type, non-type spark-ignition, such as a diesel engine.

The device management engine in the first embodiment of the present invention has the structure shown by the flowchart of figure 1. Figure 1 shows the various elements of the device control blocks and the transmission of signals between blocks by arrows. Composition and characteristics of the control device according to a variant of implementation are described below with reference to figure 1. To provide a deeper understanding of the characteristics of this variant implementation, detailed drawings can be used as necessary to describe the variants of implementation.

Referring to figure 1, the control device has a control structure of a hierarchical type, which includes three hierarchy levels 10, 20 and 30. The management structure includes, after avatele from the upper level to the lower level of the hierarchical levels, level 10 requirements, level 20 coordination and level 30 job control variables. Actuators of various types 42, 44 and 46 are connected with a level 30 job control variables at the lower level of the hierarchy. The signal travels in one direction only between levels 10, 20 and 30 of the control device, and the signal is transmitted from level 10 requirements on level 20 of the agreement and from level 20 negotiation at level 30 job control variables. The control unit additionally includes a system 50 shipping total signal, which is independent from these levels 10, 20 and 30 and delivers a common signal in parallel in each of the levels 10, 20 and 30.

The signals transmitted between the levels 10, 20 and 30 differ from delivered from the system 50 of the delivery of common signals in the following way. In particular, the signals transmitted between the levels 10, 20 and 30, is converted from requirements related to engine performance, and ultimately translated into the appropriate control variables for the actuators 42, 44 and 46. On the contrary, the signals delivered from the system 50 of the delivery of common signals include the required information, when the requirements are formed or control variables are calculated: in particular, information on the operating conditions and operating modes operation the indicator (for example, the engine speed, the amount of intake air, the estimated torque current actual ignition timing, coolant temperature, valve timing and operating mode). The sources of these types of information 52 may include sensors of different types, located on the engine, and the ability of the internal evaluation of the control device. Information of these types is General information engine, shared through levels 10, 20 and 30. Accordingly, the delivery of information in parallel in each of the levels 10, 20 and 30 not only helps to reduce the amount of data transferred between levels 10, 20 and 30, but also to maintain the simultaneity of information between levels 10, 20 and 30.

Layout each of the levels 10, 20 and 30 and the processing performed in them, are described in detail below in descending order of hierarchical levels.

Level 10 requirements, which corresponds to the output module of the requirements of the present invention, includes many of the elements 12, 14 and 16 output requirements located in it. "Claim"as that term is used herein, means that is connected with the characteristic of the engine. Each of the elements 12, 14 and 16 output requirements allocated to the relevant characteristics of the engine. Features of the engine include on saucepot, exhaust gas, fuel economy, noise and vibration, among other things. You can say that they are the performance characteristics required for the engine. The various elements of the output requirements should be located on level 10 requirements depending on what is required from the engine and what should be given priority. In this embodiment, the element 12 o requirements is provided so as to correspond to the characteristic associated with the responsive element 14 output requirements provided so as to correspond to the characteristic associated with the exhaust gas, and the second element 16 output requirements provided so as to correspond to the characteristic associated with the fuel economy.

The elements 12, 14 and 16 output requirements output numeric values that represent the requirements related to engine performance. The control variable actuators 42, 44 and 46 is determined through arithmetic operations, so that the requirements are defined quantitatively, to give the opportunity to reflect requirements in the control variables of the actuators 42, 44 and 46. In this embodiment, the following three types of physical quantities used in the expression of requirements: torque, efficiency and composition of the mixture air-to-fuel".

Products which you work (conclusions) of the engine include flammable and fumes in addition to torque, and the combination of these products determines various characteristics of the engine, including the above elements associated with the responsiveness, exhaust gas emissions and fuel economy. Options for management conclusions can be collected in three types of physical quantities associated with torque, efficiency and composition of the mixture air-to-fuel". Therefore, it is assumed that the requirements can be reliably included in the results of operation of the engine through the submission requirements in terms of three types of physical quantities associated with torque, efficiency and composition of the mixture air-to-fuel, and exercise operational control of actuators 42, 44 and 46.

In figure 1, although only typical element 12 o requirements deduces the requirement associated with the responsiveness, and the value of the requirements, expressed in torque or efficiency. For example, if the requirement is the acceleration of the vehicle, this particular requirement can be expressed in torque. If the requirement is to prevent the stop of the engine, it is a specific requirement can be expressed in efficiency (improved efficiency).

Element 14 output requirements deduces the requirement associated with the exhaust gas, and the value of Tr is a requirement, expressed in efficiency or the composition of the mixture air-to-fuel". For example, if the requirement is to heat the catalyst, this particular requirement can be expressed in efficiency (reduced efficiency) or the mixture air-to-fuel". Reduced efficiency can raise the temperature of the exhaust gas, and the composition of the mixture air-to-fuel "can specify the environment in which the catalyst is highly reactive.

Item 16 output requirements deduces the requirement associated with the fuel economy, the value of the requirements, expressed in efficiency or the composition of the mixture air-to-fuel". For example, if the requirement is to improve the combustion efficiency, it is a specific requirement can be expressed in efficiency (improved efficiency). If the requirement is to reduce pumping losses, this particular requirement can be expressed as the composition of the mixture air-fuel (combustion with depletion).

It should be noted that the value of the requirements, the output of each of the elements 12, 14 and 16 output requirements, not limited to one for each physical quantity. For example, the element 12 o requirements displays not only the demand torque from the driver (torque, calculated from the accelerator opening), but also the requirements in torque is omenta from devices of different types, as they relate to vehicle controls, such as VSC (stability control, vehicle), TRC (traction control), ABS (anti-lock brake system) and transmission. The same applies also to the effectiveness.

The system 50 delivery of common signals gives General information engine on level 10 requirements. Each of the elements 12, 14 and 16 output requirements accesses the shared information of the engine, to thereby determine the value that should be displayed. This is because the specific details of the requirements vary according to operating conditions and operating modes of the engine. If the temperature sensor catalyst (not shown) is used to measure the temperature of the catalyst, for example, element 14 output determines the need to heat the catalyst on the basis of this temperature information, and according to the definition removes the requirement in the efficiency or the composition of the mixture air-to-fuel".

The elements 12, 14 and 16 output level requirements 10 requirements eliminate many requirements, expressed in torque, efficiency or the composition of the mixture air-fuel as described above. These requirements, however, cannot be achieved in full and on time. This is stipulated what about the fact, only one requirement in torque can be achieved even with many of the requirements in torque. Similarly, only one requirement in efficiency can be achieved when many requirements in efficiency, and only one requirement in the composition of the mixture air-to-fuel "can be achieved when many requirements in the composition of the mixture air-to-fuel". This requires the reconciliation process requirements.

Level 20 coordination coordinate requirements (number of claims), the output of the level 10 requirements. Level 20 reconciliation includes items 22, 24 and 26 of the agreement, each of which is allocated to the corresponding physical quantities as classified category requirements. Item 22 reconciliation of torque, which corresponds to the matching module torque of the present invention, will agree on a single value requirements, expressed in torque, with others to achieve a single value requirements in torque. Item 24 reconciliation of efficiency, which corresponds to the matching module of the effectiveness of the present invention, will agree on a single value requirements, expressed in efficiency, with others to achieve a single value requirements in efficiency. Element 26 reconciliation of the mixture air-fuel that soo is the same as matching module of the mixture air-to-fuel "of the present invention, agree on a single value requirements expressed in the composition of the mixture air-to-fuel", with others to achieve a single value requirements in the composition of the mixture air-to-fuel". Each of the elements 22, 24 and 26 negotiation negotiates according to the predetermined rule. "Rule", as the term is used herein, means the rule of calculation to obtain a single numeric value from a set of numeric values, such as, for example, selecting the maximum value, minimum value, average or overlay. These rules calculations can be properly combined together. What rule or rules should be applied is a matter of design, and in part related to the present invention, there are no restrictions on the granularity of the rules.

Specific examples are provided below to provide a deeper understanding of the negotiation. Figure 2 is a block diagram showing a typical layout element 22 reconciliation of torque. In this example, the element 22 reconciliation of torque includes the element 202 overlay and element 204 of selecting the minimum value. In addition, the values of the requirements collected through element 22 reconciliation of torque in this example, are the requirement in torque from the driver, the loss of torque from the power accessories, the requirement torque to cut fuel consumption and the demand torque when you reset the fuel cutoff.

From the values of requirements collected through element 22 reconciliation of torque demand torque from the driver and loss of torque from the load accessories superimposed on top of each other through element 202 overlay. The output value of the element 202 blending together with the demand torque to cut fuel consumption and the demand torque when you reset the fuel cutoff is entered in element 204 of selecting the minimum value and the minimum value of them is selected. The selected value is derived from the element 22 reconciliation of torque as the target value requirements in torque, in particular the agreed value requirements in torque.

Figure 3 is a block diagram showing a typical layout element 24 matching efficiency. In this example, the element 24 matching efficiency includes three elements 212, 216 and 220 of selecting the minimum value and two elements 214 and 218 selecting the maximum value. In addition, the values of the requirements collected through element 24 coordination effectiveness in this example, include the required efficiency in responsiveness as a requirement in avicennae efficiency; the required efficiency for ISC, the desired efficiency of torque with a quick response and the desired efficiency to heat from the catalyst as requirements in reduced efficiency; and the desired efficiency for the KCS and the desired efficiency in excessive detonation as requirements in lower efficiency with higher priority.

From the values of requirements collected through element 24 matching efficiency, the required efficiency of responsiveness along with other requirements in increased efficiency is entered in element 214 selecting the maximum value. The maximum value of them is entered in element 218 selecting the maximum value. Additionally, the required efficiency for ISC, the required efficiency for torque with the rapid response and the required efficiency when heating the catalyst, together with other requirements in lower efficiency, is entered in element 216 selecting the minimum value. The minimum value of them then entered in item 218 selecting the maximum value. Element 218 selecting the maximum value selects the maximum value from the input value of the element 214 selecting the maximum value and the input value of the element 216 selecting the minimum value and introduces a maximum value in the element in the boron minimum value 220. Item selection the minimum value 220 selects the minimum value from the input value of the element 218 selecting the maximum values and the input values from the picker minimum value 212. The selected value is derived from the element 24 reconciliation of efficiency as finite value requirements in efficiency, in particular the agreed value requirements in efficiency.

Identical processing is performed also in the element 26 reconciliation of the mixture air-to-fuel", although the specific example herein omitted. As described above, specific types of elements in order to form the element 26 reconciliation of the mixture air-to-fuel "are a matter of design and the elements can be combined appropriately based on the principle of designing a specific designer.

As noted previously, the system 50 delivery of common signals gives General information engine also on level 20 of the agreement. Although General information engine is not used in the above specific examples related to elements 22, 24 reconciliation, General information engine can be used in each of the elements 22, 24 and 26 of the agreement. For example, rules for coordination can be changed according to operating conditions and operating modes of the engine. The rules, however, m is her do not change to reflect the range that must be attained by means of the engine, as described below.

As is evident from the above specific examples, the element 22 reconciliation of torque does not add to the torque upper limit or torque lower limit, which should in fact be achieved through the engine, in an orchestration. The results of the negotiation by other elements 24 and 26 approval is also not added to the agreement. This also applies to the elements 24 and 26 of the agreement, which perform the agreement without the addition of the upper and lower limits of the range, which should be achieved through the engine, or the results of the coordination of other matching elements. The upper and lower limits of the range, which must be attained by means of the engine vary depending on the operating conditions of the engine and the relationship between torque, efficiency and composition of the mixture air-to-fuel". Accordingly, the attempt to reconcile each value requirements with a range that must be attained by means of the engine, increases the workload on the computer. Each of the elements 22, 24 and 26 of the agreement, therefore, negotiates by collecting only requirements derived from level 10 requirements.

Through the above agreement, executed by each of the elements 22, 24 and 26 of the agreement, a single value requirements in torque, a single value requirements in efficiency and a single value requirements in the composition of the mixture air-fuel derived from level 20 approval. Level 30 job control variables as the next hierarchical level, the control variable of each of the actuators 42, 44 and 46 is set on the basis of the agreed value requirements in torque, the meaning of efficiency and value requirements in the composition of the mixture air-to-fuel".

Level 30 job control variable, which corresponds to the evaluation module, the control variable of the present invention, includes one unit 32 of the regulation, which corresponds to the modification module of the present invention, and many of the elements 34, 36 and 38 calculation of control variables. The elements 34, 36 and 38 of the calculation of the control variable is provided so as to correspond to, respectively, the actuators 42, 44 and 46. In this embodiment, the actuator 42 is the throttle actuator 44 is ignition device, and the actuator 46 is a fuel injection system. Accordingly, the opening of the throttle you assetsa as a control variable in the element 34 calculation of control variables, connected with the actuating mechanism 42; the ignition timing is calculated as a control variable in the element 36 calculate the control variable, which is connected with the actuating mechanism 44; and the amount of fuel injection is calculated as a control variable in the element 38 calculate the control variable, which is connected with the actuating mechanism 46.

The numeric values used to calculate the control variable by means of each of the elements 34, 36 and 38 calculate the control variables are available from the block 32 of the regulation. Request in torque, the value requirements of efficiency and value requirements in the composition of the mixture air-to-fuel", agreed by level 20 reconciliation, first subjected to regulation in absolute value by block 32 of the regulation. This is because the range that must be attained by means of the engine, not added to the agreement by level 20 coordination, as described above, so that the engine may not work properly depending on the absolute value of each value requirements.

Block 32 regulation adjust each value requirements on the basis of the relationship with each other so that a proper engine operation can be performed. The levels in the hierarchy to enter the level 30 job control variables independently evaluated each of the values of the requirements in torque, the meaning of effectiveness and value requirements in the composition of the mixture air-to-fuel, and the resulting calculated values are not used or are correlated between the different elements involved in the calculation. In particular, the request torque, the value requirements of efficiency and value requirements in the composition of the mixture air-fuel mutually correlated for the first time in block 32 of the regulation. If an attempt to regulate the absolute value of the values of the requirements at the top level of the hierarchy, the number of regulated entities is large, leading to very significant workload. When the regulation is implemented at the level of 30 job control variables, however, the number of regulated entities is limited to three, in particular, the request torque, the value of the requirements of efficiency and value requirements in the composition of the mixture air-to-fuel", requiring only a small workload for regulations.

How are regulation is a matter of design, and in part related to the present invention, there are no restrictions on the details of the regulations. If the order of priority is enabled for the meaning of torque, the meaning of efficiency and value requirements in the composition of MESI "air-fuel", however, a request with a lower priority should preferably be adjusted (modified). In particular, the value of requirements with high priority is reflected directly in the control variables of the actuators 42, 44 and 46, and the request with low priority is first adjusted, and then reflected in the governing variables of the actuators 42, 44 and 46. This ensures reliable implementation requirements with high priority and implementation requirements with low priority to the extent achievable within range to ensure proper operation of the engine. For example, if the value requirements in torque has the highest priority request in the effectiveness and value requirements in the composition of the mixture air-fuel adjusted by values having a lower priority of the two, corrected to the greatest extent. If the order of priority is changed depending on, for example, from the operating conditions of the engine, the order of priority is determined on the basis of General information engine delivered from the system 50 of the delivery of common signals, thereby determining what is the requirement should be adjusted.

Specific examples are provided below to provide a deeper understanding of the Blo is and 32 of the regulation. Figure 4 is a block diagram showing a typical layout of block 32 of the regulation. In this example, the mode of operation of the engine includes a preferred mode, the efficiency and the preferred mode, the composition of the mixture air-to-fuel". Below describes the layout, which give the possibility of changing the aforementioned order by priority according to the operating mode. The operating mode is included in General information engine and is delivered in block 32 of regulation through the system 50 of the delivery of common signals.

In the layout shown in figure 4, block 32 regulation includes protective block 302, limiting the upper and lower limits of the requirements of efficiency. Protective unit 302 adjusts the value requirements of efficiency, coordinate through the element 24 reconciliation of efficiency, so that the value requirements in efficiency is within the range of proper operation of the engine. Block 32 regulation also includes a protective block 316, limiting the upper and lower limits of the requirements in the composition of the mixture air-to-fuel". Protective block 316 adjusts the value of requirements in the composition of the mixture air-to-fuel", coordinate through the element 26 reconciliation of the mixture air-to-fuel", so that the value requirements in composition (Mus) and "air-fuel" is within the range of proper operation of the engine. The upper and lower limit values of each of the protective blocks 302, 316 are variable in such a way as to be variable way, mutually functionally associated with each other. The following describes how this works.

For upper/lower limit values of the effectiveness of the protective block 302 available upper/lower limit value (for the preferred mode of performance), when the preferred mode efficiency is selected as the operating mode, and the upper/lower limit value (for preferred mode on the composition of the mixture air-to-fuel"), when the preferred mode, the composition of the mixture air-to-fuel "is selected as the operating mode. Changing the bounding range of protective block 302 provides the ability to control the absolute value of the requirements in efficiency. Block 308 selection selects any type of upper/lower limit values of efficiency according to the operating mode and sets the selected upper/lower limit values of the efficiency in a protective block 302.

Upper/lower limit values of the efficiency for preferred mode on efficiency are the upper/lower limit values over a range of composition of the mixture air-to-fuel", and the values stored in the storage device 304 suggest that if the expansions. Upper/lower limit values of the efficiency for the preferred mode, the composition of the mixture air-to-fuel", on the other hand, represent the upper/lower limit values of the efficiency with which it is possible to prevent detonation and misfire when the preferred composition of the mixture air-to-fuel". These values are read from the schema 306 on the basis of operating conditions, including engine speed, the target torque and phases. Request in the composition of the mixture air-fuel that is processed by protective block 316, is introduced into the circuit 306, and with reference to this value requirements in the composition of the mixture air-to-fuel" is defined upper/lower limit values of the efficiency.

For upper/lower limit values of the mixture air-fuel protective block 316 available upper/lower limit value (for the preferred mode of performance), when the preferred mode efficiency is selected as the operating mode, and the upper/lower limit value (for preferred mode on the composition of the mixture air-to-fuel"), when the preferred mode, the composition of the mixture air-to-fuel "is selected as the operating mode. Changing the bounding range of protective block 316 enables regulation of absolutevalue value requirements in the composition of the mixture air-to-fuel". Block 322 selection selects any type of upper/lower limit values of the mixture air-fuel according to the operating mode and sets the selected upper/lower limit value of the mixture air-fuel protective block 316.

Upper/lower limit value of the mixture air-to-fuel "for preferred mode on the composition of the mixture air-to-fuel "represents the upper/lower limit value across the range of effectiveness, and the values stored in the storage device 318 is read. Upper/lower limit value of the mixture air-to-fuel "for preferred mode on efficiency, on the other hand, represent the upper/lower limit value of the mixture air-to-fuel", in which you can avoid detonation and misfire in the preferred efficiency. These values are read from the circuit 320 based on the operating conditions, including engine speed, the target torque and phases. The efficiency of the torque that is processed by protective block 314, which shall be described below, is introduced into the circuit 320, and with reference to the efficiency of the torque is determined upper/lower limit value of the mixture air-to-fuel". Method of determining and calculating the efficiency and torque is described below.

Figure 5 is a diagram showing the method for setting upper/lower limit values of efficiency using the scheme 306. 6 is a diagram showing the method for setting upper/lower limit values of the mixture air-fuel using circuit 320. In each drawing, the ordinate represents the efficiency, and the abscissa represents the composition of the mixture air-to-fuel". The curve shown in the drawing, is a line of ignition limit. The area below the line of the ignition limit is NG-region, which may not run properly. Line ignition limit depends on the operating conditions, including engine speed, the target torque and phase distribution.

First, when the preferred mode, the composition of the mixture air-to-fuel "is selected as the operating mode, the value of the requirements in the composition of the mixture air-fuel is introduced into the circuit, as shown in figure 5. The value of efficiency corresponding to the request in the composition of the mixture air-fuel in-line ignition limit, is then calculated. This value is set as the lower limit value of the effective value requirements in the composition of the mixture air-fuel α. The preset value (for example, 1) is used for the upper limit of efficiency. Preset lower PR is good value efficiency and the upper limit value of efficiency is defined in the protective unit 302 by block 308 of choice.

If the preferred mode efficiency is selected as the operating mode, the efficiency of β torque is introduced into the circuit as shown in Fig.6. The importance of the composition of the mixture air-fuel corresponding efficiency β torque on the line of the ignition limit is then calculated. In the case shown in the drawing, two large and small values of the mixture air-fuel corresponding efficiency β torque, there are, the larger value is set as the upper limit value of the mixture air-fuel efficiency β torque, and a smaller value is set as the lower limit value of the mixture air-fuel efficiency β torque. The lower limit value of the mixture air-to-fuel" and set the upper limit value of the mixture air-to-fuel "is defined in the protective block 316 by block 322 of choice.

Additionally, the block 32 regulation can generate a new signal using the values of the request entered from level 20 coordination, and General information engine delivered from the system 50 of the delivery of common signals. In the example shown in figure 4, unit 312 calculates the ratio between the value requirements in torque, coordinate through item 2 approval of torque and the estimated torque is included in General information engine.

The calculation of the estimated torque is performed by another task.

The relationship between the request torque and the estimated torque calculated by unit 312, is efficiency torque. Protective block 314 limits the upper and lower limits of torque. Upper/lower limit values of efficiency, selectable by block 308 of choice, set in a protective block 314. In particular, limiting the range of this protective block 314 is defined in the same way as for the defensive unit 302, which limits upper/lower limits values requirements in efficiency.

As a result of the above processing, the signals output from the block 32 of the regulation, are important requirements in torque, the adjusted value of the requirements of efficiency, the adjusted value requirements in the composition of the mixture air-fuel and the efficiency of torque. From these signals, the request torque and the adjusted value requirements in efficiency are entered in item 34 of the calculation of the control variable. The element 34 calculate the control variable now is La divides the value requirements in torque on the adjusted value requirements in efficiency. Because the adjusted value requirements in efficiency is a value equal to or less than 1, the value requirements in torque is corrected to be increased by this division. Adjusted to increase the value requirements in torque then translated into a volume of air from which is calculated the opening of the throttle.

Efficiency, torque is introduced as the main signal in the element 36 calculation of control variables. The request torque and the adjusted value requirements in the composition of the mixture air-to-fuel "also entered as reference signals. The element 36 of the control variable calculation calculates the angle of lag relative to the MBT of the efficiency of torque. The lower the efficiency of the torque, the greater the value of the angle of lag. This leads to a decrease in torque. The sharp increase in value requirements in torque, which is performed through the element 34 calculate the control variable, is the process of compensating the reduction of torque due to lag. In this embodiment, the request torque and the request in efficiency can be achieved through the delay distribution of ignition on the Nove efficiency, torque, and by the sharp increase in value requirements in torque based on the requirements of efficiency. The request torque and the adjusted value requirements in the composition of the mixture air-fuel entered in item 36 calculate control variables are used to select layouts to convert efficiency torque to the angle of lag. The final ignition timing calculated from the value of the angle of lag and MBT (or basic ignition timing).

The adjusted value requirements in the composition of the mixture air-to-fuel" is entered in element 38 calculation of control variables. The element 38 of the control variable calculation calculates the amount of fuel injection from the adjusted value requirements in the composition of the mixture air-to-fuel "and value of the intake air in the cylinder. The amount of intake air is included in General information engine and delivered to the element 38 calculate the control variable of the system 50 of the delivery of common signals.

As described above, in the control device of the present variant implementation requirements associated with the responsiveness, exhaust gas emissions and fuel economy, which are elements of the engine performance, expressed in terms of torque, efficiency is Yunosti or mixture "air-fuel". Torque, efficiency and composition of the mixture air-fuel are the three main factors that determine the results of the internal combustion engine. Therefore, the use of these physical quantities in order to represent the requirements associated with the above characteristics, and calculate control variables actuators 42, 44 and 46 based on the requirements in torque, the meaning of efficiency and value requirements in the composition of the mixture air-fuel obtained by matching the above requirements, ensures the proper operational management of actuators 42, 44 and 46 so that the requirements are included in the results of operation.

According to the control device of the present case for features that should be implemented, can be easily added. 7 is a block diagram showing the configuration in which the characteristic associated with the detonation added as new. In the configuration in Fig.7 element 72 output requirements, suitable for the new characteristics that are included in level 10 requirements. Requirements associated with detonation, can be expressed in terms of efficiency, one of the three main factors (torque, efficiency and composition of the mixture is asdoh-fuel"), which determine the results of operation of the engine. Value requirements, the output of element 72 output requirements, therefore, entered in item 24 matching efficiency.

The signals are transmitted in one direction from level 10 requirements on level 20 of the agreement, and at level 10 generate requirements signals are not transmitted between elements within the same hierarchical level, so that adding a new element 72 output requirements does not change the other circuit elements. Value requirements, which are derived from an added element 72 output requirements, together with values that are derived from other elements output requirements (namely, the elements 12, 14 and 16), element 24 reconciliation of efficiency, whereby the output requirements then aligned into a single value requirements in efficiency.

Item 24 reconciliation of effective coordinate values only in accordance with predetermined rules. Even if the number of values of requirements that must be collected increases, the associated increase in the arithmetic load is very small. In addition, it should remain in that only the value of the requirements in torque, the value requirements of efficiency and value requirements in ed the ve mixture air-fuel derived from level 20 negotiation at level 30 job control variables so the arithmetic load on level 30 job control variable is not increased. Briefly, according to the control device of the present version of the implementation characteristics of the engine, which must be implemented, can be added without increasing the arithmetic load on the computer.

In addition, according to the control device of the present case for easy add actuators to be used for motor control. Fig is a block diagram showing the configuration in which the controller of the adjustable valve lift added as a new actuator to do the maximum lift of the intake valves variable. As shown in Fig to add a new enforcement mechanism (controller adjustable valve lift) 76, only the corresponding element 74 calculation of the control variable must be additionally provided at the level of 30 job control variables and is connected to the block 32 of the regulation. In element 74 calculate the control variable amount of lift of the intake valves is calculated using the signal output from the block 32 of the regulation. Signal transmission from the block 32 of regulation in each element of the calculation of the control variable is unidirectional, and the signals are not p is Reduta between the elements of the calculation of the control variable, so adding a new element 74 calculation of control variables does not change the other circuit elements.

The second option of carrying out the invention

Next, a second variant implementation of the present invention is described with reference to the accompanying drawings. Fig.9 is a block diagram showing the configuration of the device management engine of the second variant embodiment of the invention. Figure 9, the same reference positions denoted by identical elements in common with elements of the first variant implementation. In the following paragraphs a description of the elements common to the elements of the first variant implementation is omitted or simplified, and the focus is mainly on the characteristic blocks of this variant implementation.

The control device of the present version of the implementation is different in the elements 12, 14 and 16 output requirements. The elements 12, 14 and 16 output requirements are made so that if only non-standard requirements arise, displays the values of the requirements for elements, expressed in terms of efficiency or the composition of the mixture air-to-fuel". Additionally, the block 62 storage that stores default values for the value requirements of efficiency and value requirements in the composition of the mixture air-to-fuel", there is a level 30 job control p the belt, and more specifically, in block 32 of the regulation. These default values are stored in the form of correspondences, together with the operating parameters and the operating conditions of the engine. Block 32 regulation made so that, if the value requirements in efficiency is not output from the element 24 reconciliation of efficiency or if the value requirements in the composition of the mixture air-fuel not derived from the element 26 reconciliation of the mixture air-to-fuel", block 32 regulation of alternative uses the appropriate default values stored in block 62 storage in order to perform evaluation.

Three main factors (torque, efficiency and value requirements in the composition of the mixture air-to-fuel"), which determine the results of the engine, the request torque, in particular, is a mandatory requirement when driving the motor, and this demand is constantly changing. On the contrary, the value requirements of efficiency and value requirements in the composition of the mixture air-fuel usually remain fixed and invariant, and both of them usually change only when there is some situation. Therefore, only if the requirements of efficiency and value requirements in the composition of the mixture air-fuel differ from those of a hundred the standard values, the relevant requirements are displayed, and when the standard data requirements are calculated using standard values. The arithmetic load on the control device, and more specifically, the load level 10 requirements and level 20 approval thereby may be reduced. In this case, the default values should be used alternatively, when control variables actuators 42, 44 and 46 are calculated, and thus, each of these actuators can be controlled properly so that the engine failure does not occur during engine operation.

The third variant embodiment of the invention

Next, the third alternative implementation of the present invention is described with reference to the accompanying drawings. Figure 10 is a block diagram showing the configuration of the device management engine of the third variant embodiment of the invention. Figure 10 the same reference positions denoted by identical elements in common with elements of the first variant implementation. In the following paragraphs a description of the elements common to the elements of the first variant implementation is omitted or simplified, and the focus is mainly on the characteristic blocks of this variant implementation.

The control device of the present VA is Ianto implementation is different in the configurations of the element 24 reconciliation of efficiency and element 26 reconciliation of the mixture air-to-fuel". Item 24 matching efficiency includes block 64 storage that stores default values for each element, the corresponding values of requirements that must be removed from the elements 12, 14 and 16 output requirements. These default values are stored in the form of correspondences, together with the operating parameters and the operating conditions of the engine. For elements corresponding to values of requirements that should not be derived from elements 12, 14 and 16 output requirements, item 24 matching efficiency is made with the ability to reconcile the demands of efficiency using the stored standard values.

Element 26 reconciliation of the mixture air-to-fuel "includes block 66 storage that stores default values for each element, the corresponding values of requirements that must be removed from the elements 14 and 16 output requirements. These default values are stored in the form of correspondences, together with the operating parameters and the operating conditions of the engine. For elements corresponding to values of requirements that should not be derived from elements 14 and 16 output requirements, item 26 reconciliation of the mixture air-fuel made with the possibility to reconcile the requirements in the composition of the mixture air-that is people using the stored standard values.

The elements 12, 14 and 16 output requirements are made so that if the only requirements that differ from the standard, arise displays the values of the requirements for elements, expressed in terms of efficiency or the composition of the mixture air-to-fuel". Thus, the values requirements are only displayed in case of non-standard requirements and standard requirements for approval in the elements 24 and 26 reconciliations are carried out using standard values. This provides a reduction of arithmetic load control device, in particular the arithmetic load on level 10 requirements. Additionally, because the value of the requirements of efficiency and value requirements in the composition of the mixture air-fuel reliably derived from elements 24 and 26 of the agreement, respectively, the actuators 42, 44 and 46 can be properly managed so that the engine failure does not occur during engine operation.

Types of actuators, which must be controlled in the present invention is not limited by the choke, ignition device, fuel injection or device regulated valve lift. For example, as actuators, which must be managed, can be used by the control unit phases gazoraspredeleniye the (WT) and the external EGR device. In addition, the engine is equipped with cylinder deactivation mechanism and the mechanism variable compression ratio, these mechanisms can be used as actuators, which must be managed. In an engine with a turbocharger with an auxiliary motor (MAT) MAT can be used as the actuator, which must be managed. In addition, as the actuators can be used alternator and other accessories, which actuates the motor, because the motor terminal can similarly be controlled through the use of your accessories.

The present invention is not limited to the above variants of the implementation and can be modified in various forms without departure from the essence and scope of the invention. In the above described embodiments implement, for example, the delivery system common signal is used to deliver signals (General information)associated with operating parameters and the operating conditions of the engine. Alternatively, these signals can be delivered together with the values of the requirements of the higher hierarchical level to a lower level. Compared with the use of the delivery system of common signals using the such alternative method for to transmit signals between the hierarchical levels, increases the volume of transmitted signals. However, since the signals are transmitted in only one direction, significant growth arithmetic load does not occur.

Conflict settled and setting required inverse conversion of physical magnitude, control instrument outputs memorised setting to make a device setting. Said device can made a vehicle traction force source. In setting generation, first and second settings are generated. First setting is base don driver manipulations (S100). Second setting is not based on driver manipulations. When engine makes the vehicle traction force source, first setting "a" is expressed in torque units (S200). Second setting "A" is expressed in traction force units (S400). On converting physical magnitudes, conversion into units of traction forces (S500) is carried out. First setting "a" (S300) is memorised. If first setting is selected after conflict settling (no S600), memorised first setting "a" (S900) is set for the engine.

EFFECT: better vehicle controllability.
