DESCRIPTION of the PREFERRED embodiments of the INVENTION

Embodiments of the present invention will be described in detail with reference to the drawings.

Figure 1 depicts the overall scheme of the design of the system power supply for a vehicle according to a variant implementation of the present invention. With reference to Figure 1, the power supply system for a vehicle 10 includes an electrically powered vehicle 100 and the device 200 outlets. Electrically powered transport is the first tool 100 includes a reception unit 110 energy, the camera 120 and the block 130 connection.

Unit 110 receiving energy attached to the underbody of the vehicle and configured to receive electric power transmitted from the block 220 energy transfer (which will be described later) of the device 200 power supply contactless manner. More precisely, the block 110 receiving energy includes samaritano coil (which will be described later) and receives electrical energy from a block 220 of energy transfer in a non-contact manner, resonating with samaritane coil included in block 220, the transfer of energy through electromagnetic field. The camera 120 is provided for reading the relative position between the block 110 of reception of energies and block 220 power transmission and attached to the body of the vehicle so that she could capture the image behind the vehicle. Block 130 communication is a communication interface for conducting communications between the electrically powered vehicle 100 and the device 200 outlets.

The device 200 power includes the device 210 of the power supply unit 220 energy transfer, light-emitting blocks 230 and block 240 connection. The device 210 of the power supply converts the energy of industrial alternating current (AC)supplied from power source system, for example, in a high-frequency electric energy in the network such in block 220 of energy transfer. High-frequency electric energy generated by the device 210 of the power supply, for example, has a frequency of from 1 to more than ten MHz.

Block 220 energy transfer is fastened to a floor surface Parking space and configured to transmit a high-frequency electric power supplied from the device 210 of the power supply unit 110 receiving energy electrically powered vehicle 100 contactless manner. More precisely, the block 220 power supply includes samaritano coil (which will be described later), and transmits electrical energy in block 110 receiving energy in a contactless manner, resonating with samaritane coil included in block 110 of receiving energy via an electromagnetic field. Multiple light-emitting units 230 are provided in block 220 energy transfer to indicate the position of block 220 of energy transfer. Each of the light emitting units 230, for example, includes a LED (light-emitting diode, LED). Block 240 communication is a communication interface for conducting communications between the device 200 outlets, and electrically powered vehicle 100.

In the power supply system for vehicle 10 unit 220 of the power transmission device 200 transmits power high-frequency electric energy, and samaritana coil included in block 110 receiving the energy of the electron is rejeski powered vehicle 100, and samaritana coil included in block 220 energy transfer, resonate with each other through the electromagnetic field, thereby feeding electrical energy from the device 200 power to electrically powered vehicle 100. For supplying electrical energy from the device 200 power to electrically powered vehicle 100, an electrically powered vehicle 100 must be positioned on the device 200, the power to adjust the positioning unit 110 receiving energy electrically powered vehicle 100 on the position of the block 220 power transmission device 200 outlets. In the present embodiment, Parking management electrically powered vehicle 100 with respect to the device 200, the power supply is performed in two stages.

Namely, in the first stage, the mutual position between the block 110 of the reception energy of electrically powered vehicle 100 and the block 220 power transmission device 200, the power is read on the basis of the image captured by the camera 120, and the vehicle is controlled so that it was directed at block 220 of energy transfer on the basis of the read result. More precisely, the image of the set of light-emitting units 230 installed on the unit 220 energy transfer, snime is by the camera 120, and the position and orientation of the multiple light emitting units 230 are recognized by image recognition. Then the position and orientation of block 220 of energy transfer and the vehicle are detected based on the result of image recognition and vehicle induced on the block 220 of energy transfer on the basis of the recognition result.

The area where the reception unit 110 energy and the block 220 energy transfer facing each other, is smaller than the area of the underbody of the vehicle. When the block 220 energy transfer is under the body of the vehicle and the camera 120 can no longer capture the image block 220 energy transfer, Parking management switches from the first stage to the second stage. In the second stage, electric power is supplied from the block 220 energy transfer in block 110 receiving energy, and the distance between the unit 220 of the power transmission unit 110 and the reception power is read on the basis of the conditions of supply of electric energy. Then the vehicle is controlled so that the position of the block 110 receiving energy was tuned to the position of block 220 of energy transfer on the basis of the information about the distance.

Electrical energy is transferred from block 220 energy transfer in the second stage, described above, is configured to be men who necks, than the electric energy supplied from block 220 energy transfer in block 110 receive power after the position adjustment unit 110 receiving energy at the position of the block 220 energy transfer. This is because the transmission of electrical energy from the block 220 energy transfer in the second stage, described above, is designed to read the distance between the block 220 power transmission and reception unit 110 of energy, and do not need a big electric energy for the actual supply of electric energy.

Then you will learn how contactless power used in the power supply system for vehicle 10 according to the present variant implementation. In the power supply system for vehicle 10 according to the present variant, the electrical power is supplied from the device 200 power to electrically powered vehicle 100 through resonance.

Figure 2 illustrates the principles of energy transfer through resonance. With reference to Figure 2, this resonance is such that when two coils LC resonance having the same natural frequency, resonate with each other in an electromagnetic field (near field) in the same way that two tuning forks resonate with each other, the electric energy is transferred from one coil to another coil through lektromagnitnoe field.

More accurately high-frequency source 310 power supply connected to the primary coil 320, and a high-frequency electric energy from 1 to more than ten MHz is fed into the primary samaritano coil 330, magnetically connected with the primary coil 320 by electromagnetic induction. Primary samaritana coil 330 is an LC resonator having an inductance of the coil and parasitic capacitance, and resonates with the secondary samaritane coil 340 having a resonant frequency, the same as the primary samaritane coil 330, through an electromagnetic field (near field). Therefore, the energy (electric power) is transferred from the primary samaritane coil 330 to secondary samaritano coil 340 through the electromagnetic field. The energy (electric power)is transferred in the secondary samaritano coil 340 is removed by the secondary coil 350, magnetically connected with the secondary samaritane coil 340, through electromagnetic induction, and is issued to a load 360. Transmission of electric energy through resonance is realized when the value of Q (q)indicating the strength of the primary resonance samaritane coil 330 and the secondary samaritane coil 340, for example, is greater than 100.

The ratios of conformity with Figure 1 secondary samarasa Anna coil 340 and the secondary coil 350 correspond to the block 110 receiving energy in figure 1, and the primary coil 320 and the primary samaritana coil 330 correspond to the block 220 energy transfer figure 1.

Figure 3 shows the relationship between the distance from the current source (magnetic current source) and the magnetic field. With reference to Figure 3 of the electromagnetic field contains three components. Curve k1 represents a component inversely proportional to the distance from the source of the wave, and is indicated by reference as "the electromagnetic field". Curve k2 represents a component inversely proportional to the square of the distance from the source of the wave, and is indicated by reference as "electromagnetic field induction. Curve k3 represents a component inversely proportional to the cube of the distance from the source of waves, and is indicated by reference as "static electromagnetic field".

These electromagnetic fields include the area where the intensity of the electromagnetic wave decreases sharply with distance from the source of the waves. The resonance it uses near field (minor field) for energy transfer (electric energy). That is, through the promptings of the pair of resonators (for example, a pair of windings LC-resonance)having the same natural frequency to resonate with each other using the fields in the near zone, the energy (electric power) is transferred from one of the Rezo is atarov (primary samaritane coil) to the other resonator (secondary samaritano coil). Because the energy (electric energy) does not cover a large distance in the field in the near zone, the resonance can transmit electrical energy with less energy loss than the electromagnetic wave that carries energy (electrical energy) in "the electromagnetic field", in which the energy is spread over a large distance.

Figure 4 depicts a detailed circuit construction of electrically powered vehicle 100 shown in figure 1. With reference to Figure 4 of electrically powered vehicle 100 includes device 150 energy storage, the main relay SMR1 system, inverter 162 with increasing voltage, inverters 164, 166, motor generators 172, 174, the motor 176, the device 177 fission energy and the drive sprocket 178.

Electrically powered vehicle 100 moves the driving force produced by the at least one motor 176 and the motor generator 174. The mechanical energy produced by the motor 176 is divided into two tracts device 177 fission energy. Namely, one is a path for transmitting energy to a driving wheel, and the other is a path for transmitting energy to the motor-generator 172.

Engine-generator 172 is a rotating electric machine AC and, for example, includes a three-phase synchronous AC motors having a rotor which has a permanent magnet. Engine-generator 172 generates electric power using kinetic energy of the motor 176, which was split device 177 fission energy. When the state of charge (also indicated by reference as "SOC") devices 150 energy storage becomes lower than a predetermined value, for example, the motor 176 is triggered and the motor-generator 172 generates electric power to charge the device 150 energy storage.

As the motor-generator 172, the motor-generator 174 is a rotating electric machine AC and, for example, includes a three-phase synchronous AC motors with other, which has a permanent magnet. Engine-generator 174 generates a driving force by using at least one of the electric energy accumulated in the device 150 energy storage, and electric power generated by motor generator 172. The driving force of the motor-generator 174 is transmitted to a driving wheel 178.

During braking of the vehicle or during the descent speed on the downward slope, the mechanical energy stored by the vehicle in the form of kinetic energy and potential energy, is used by the drive wheel 178 to bring the motor-generator 174 in rotation, so that the motor-generator 174 acts as a power generator. As a result, the motor-generator 174 acts as a regenerative brake for converting the energy of motion into electrical energy to generate the braking force. Electrical energy produced by the engine-generator 174 is stored in the device 150 energy storage.

The device 177 fission energy includes a planetary transmission having a sun gear, pinion gear, and drove the crown gear. Leading gear engages with a sun gear and a crown gear.

The device 150 energy storage accumulates electric energy supplied from the inverter 142 DC/DC, and also accumulates the regenerative electric power generated by motor generators 172, 174.

The main R is Le SMR1 system electrically attaches the device 150 accumulation of energy to the inverter 162 with increasing voltage, when activated by a signal SE1 from the device 180 control, and interrupts the electrical path between the device 150 energy storage and inverter 162 with increasing voltage when the signal SE1 deactivated. Converter 162 with increasing voltage increases the voltage line PL2 positive electrode to be equal to or higher than the voltage outputted from the device 150 energy storage, in response to a signal PWC from the device 180 controls. Converter 162 with increasing voltage, for example, includes circuit breaker DC. Inverters 164, 166 are provided respectively for the motor generators 172, 174 in the specified order. Inverter 164 energizes the motor-generator 172 in response to the signal PWI1 from the device 180 controls and inverter 166 energizes the motor-generator 174 in response to a signal PWI2 from the device 180 controls. Each of the inverters 164, 166, for example, includes a three-phase bridge circuit.

Secondary samaritana coil 112 is a coil LC resonance with open (unconnected) opposite ends and receives electrical energy from the device 200 power, resonating with the primary samaritane coil (which will be described later) of the device 200 power through the electromagnetic field. Capacitive component of the secondary samaritanspurse 112 is the parasitic capacitance of the coil, however, there may be a capacitor connected to both ends of the coil. The coils of the secondary samaritane coil 112 are configured to have a large value of Q (e.g. Q>100), indicating the strength of the primary resonance samaritane coil and the secondary samaritane coil 112, greater than κ, indicating the degree of their connection, and the like on the basis of distance from the primary samaritane coil device 200 outlets, the resonant frequency of the primary samaritane coil and the secondary samaritane coil 112, and the like.

The secondary coil 114 is installed coaxially with the secondary samaritane coil 112 and can be magnetically connected with the secondary samaritane coil 112 by means of electromagnetic induction.

With reference to Figure 5, the device 180 includes IPA-ECU 410 (electronic control unit intelligent Parking assistance), EPS 420 (steering electric steering), MG-ECU 430 (electronicbook control the motor-generator, ECB 440 (brake with electronic control), EPB 450 (electric Parking brake), the resonance ECU 460 and HV-ECU 470 (electronic control unit of a hybrid vehicle).

IPA-ECU 410 performs management guidance on putting the vehicle on the block 220 power transmission device 200 power (Figure 1) on the basis of information of the image received from camera 120 (the first management guidance), when the operation mode of the vehicle is charging mode. More precisely, IPA-ECU 410 recognizes the block 220 of energy transfer on the basis of image information received from the camera 120. Multiple light-emitting units 230, indicating the position and orientation of block 220 transmit power is set at block 220 energy transfer, IPA-ECU 410 recognizes the mutual position with respect to block 220 energy transfer (basic spacing and orientation) based on the image multiple light-emitting units 230, shown in the chamber 120. Then IPA-ECU 410 issues a command in EPS 420 on the basis of the recognition result so that the vehicle was directed in the proper orientation at the block 220 energy transfer.

When the vehicle approaches the block 220 energy transfer, and block 220 energy transfer is under the body of the vehicle so that the camera 120 could no longer fun is th image block 220 energy transfer, IPA-ECU 410 notifies the HV-ECU 470 on the completion of control of induction on the basis of image information from the camera 120 (first control guidance). During the first management guidance EPS 420 automatically performs the steering control in response to a command from the IPA-ECU 410.

MG-ECU 430 controls the motor generators 172, 174 and transducer 162 with increasing voltage in response to a command from the HV-ECU 470. More precisely MG-ECU 430 generates the signals for the excitation of the motor generators 172, 174 and Converter 162 with increasing voltage and outputs in such inverters 164, 166 and the Converter 162 with increasing voltage, respectively.

ECB 440 controls the braking of the vehicle in response to a command from the HV-ECU 470. More precisely, the ECB 440 controls the hydraulic brake and manages the coordination between the hydraulic brake and the regenerative brake by the engine-generator 174 in response to a command from the HV-ECU 470. EPB 450 controls the electric Parking brake in response to a command from the HV-ECU 470.

The resonance ECU 460 receives information about the electrical energy transmitted from the device 200 power (Figure 1), from the device 200 power via the power connection 130. The resonance ECU 460 also receives detektirovanie value for the voltage VH, which indicates the voltage of the reception on the vehicle, the sensor 190 (Figure 4). Then reason is sny ECU 460 reads the distance between unit 220 of the power transmission device 200 power supply unit 110 and the reception energy of the vehicle, comparing the voltage of the electrical energy transmitted from the device 200 power supply, with voltage VH.

More precisely in relation to the constant voltage of the primary side (the output voltage of the device 200 power), as shown in Fig.6, the voltage of the secondary side voltage of admission to electrically powered vehicle 100 changes according to the distance L between unit 220 of the power transmission device 200 power supply unit 110 and the reception energy of electrically powered vehicle 100, as shown in Fig.7. Accordingly, through an advance determination of dependence between the voltage of the primary side and the voltage of the secondary side shown in Fig.6 and 7, and the creation of the control characteristic or the like, the distance between the block 220 power transmission and reception unit 110 energy can be read on the basis of detektirovanie voltage to the voltage VH, which indicates the voltage of the secondary side.

Current primary side (the output current of the device 200 power) varies with the distance L between the block 220 power transmission and reception unit 110 energy, as shown in Fig. Accordingly, the distance between the block 220 power transmission and reception unit 110 energy can be read on the basis of detektirovanie value of the output current from the device 200 power through the use of this ratio.

Returning to Figure 5, the resonance ECU 460 reads the distance between the block 220 power transmission and reception unit 110 energy and provides information about the distance in the HV-ECU 470. In addition the resonance ECU 460 receives a command to start the charging of the HV-ECU 470 and activates the signal SE2 output onto the main relay SMR2 system to activate the main relay SMR2 system. Then the resonance ECU 460 generates a signal for excitation of the transducer 142 DC/DC and issues in such a Converter 142 DC/DC.

When the operating mode of the vehicle is a mode of motion, HV-ECU 470 outputs a control command to the MG-ECU 430 and ECB 440 in accordance with the operational state of the accelerator pedal and the brake pedal traveling conditions of the vehicle, and the like. When the driver gives a command to actuate the Parking brake operating switch Parking brake, or the like, HV-ECU 470 outputs an operating command in EPB 450.

When the operating mode of the vehicle is charging mode, the HV-ECU 470 establishes communication with the device 200 power (Figure 1) through the block 130 communications and issues a command to activate the activation device 200 outlets in the device 200 power via the power connection 130. When the device 200 power supply is activated, the HV-ECU 470 outputs a command of radiation to the light-emitting units 230 installed on a nl is ke 220 power transmission device 200 outlets, the device 200 power via the power connection 130. When the light emitting units 230 emit, HV-ECU 470 outputs a signal during control of induction, indicating that controls the mouse pointer electrically powered vehicle 100 at block 220 energy transfer, the device 200 power through the block 130 communications and issues a command to perform control of induction on the basis of image information from the camera 120 (first control guidance) in IPA-ECU 410.

Additionally, the HV-ECU 470 receives notification of the completion of the first management guidance from IPA-ECU 410 and performs management guidance based on the information about the distance between the block 220 power transmission and reception unit 110 energy (the second management guidance). More precisely, the HV-ECU 470 receives information about the distance between unit 220 of the power transmission device 200 power supply unit 110 and the reception energy of the vehicle from the resonance ECU 460 and issues commands based on the information about the distance, MG-ECU 430 and ECB 440 for controlling the drive and braking of the vehicle, respectively, so that the distance between the block 220 power transmission and reception unit 110 energy was minimal distance.

Determining that the distance between unit 220 of the power transmission unit 110 and the reception energy is AI is the minimum distance, is produced when the differential value of the distance L between the block 220 power transmission and reception unit 110 of the energy received from the resonance ECU 460, becomes zero, for example, as shown in Fig.9.

Returning to Figure 5, upon completion of the alignment unit 220 of the power transmission unit 110 receiving energy, HV-ECU 470 outputs an operating command in EPB 450, and then issues a command to supply electric power to supply electrical energy from the device 200 outlets in the device 200 power via the power connection 130, and issues a command to start charging in the resonance ECU 460.

The device 180 controls when the operation mode of the vehicle is included in the charging mode, the HV-ECU 470 establishes communication with the device 200 power via the power connection 130 and transmits a command to activate the device 200 power via the power connection 130. When the device 200 power supply is activated in response to the command activation, HV-ECU 470 transmits the radiation to the light-emitting units 230 in the device 200 power via the power connection 130. When the light emitting units 230 in block 220 transfer energy to emit, HV-ECU 470 transmits a signal during control of induction in the device 200 power through the block 130 communications and issues a command to perform control of induction on the basis of image information from the camera 120 (first administered the I-hover') in IPA-ECU 410.

IPA-ECU 410 receives a command from the HV-ECU 470 performs management guidance on the basis of image information from the camera 120 (the first management guidance) and issues a command for automatic steering EPS 420. When the vehicle approaches the block 220 energy transfer, and block 220 energy transfer is under the body of the vehicle so that the camera 120 can no longer recognize the block 220 energy transfer, IPA-ECU 410 notifies the HV-ECU 470 on the completion of the first management guidance.

The resonance ECU 460 receives information about the electrical energy transmitted from the device 200 outlets, in response to the signal during control of induction (electric energy, which is less than the electrical energy supplied after Parking management, as described above) of the device 200 power via the power connection 130 and receives detektirovanie value for the voltage VH, which indicates the voltage admission to electrically powered vehicle 100, the sensor 190 voltage. Then the resonance ECU 460 evaluates the distance between unit 220 of the power transmission unit 110 and the reception power on the basis of the conditions of supply of electrical energy from the device 200 power to electrically powered vehicle 100, and outputs the distance information in the HV-ECU 470. HV-ECU 47 receives notification of the completion of the first management guidance on the basis of image information from the camera 120 of the IPA-ECU 410 and performs management guidance based on the information about the distance between the block 220 transmission energy unit 110 and the reception energy, adopted from the resonance ECU 460 (second management guidance), and issues commands to automatically control the drive and braking of the vehicle in the MG-ECU 430 and ECB 440, respectively.

Then upon completion of the alignment unit 220 of the power transmission unit 110 receiving energy through a second control guidance, HV-ECU 470 outputs an operating command in EPB 450, and then issues a command to supply electric power to the device 200 power via the power connection 130, and issues a command to start charging in the resonance ECU 460. Therefore, begins the actual flow of electrical energy from the device 200 outlets in the electrically powered vehicle 100.

Figure 10 depicts a functional diagram of a device 200 power supply, shown in figure 1. With reference to Figure 10, the device 200 power supply includes a source 250 AC power, the driver 260 high-frequency energy, the primary coil 222, the primary samaritano coil 224, the sensor 272 voltage sensor 274 current, light-emitting blocks 230, block 240 communication and ECU 270.

Source 250 AC power is the power source outside the vehicle and, for example, the power supply system. Shaper 260 high-frequency energy transforms electrical energy is Gia, adopted from source 250 AC power, high-frequency electric power and supplies the converted high-frequency electric energy to the primary coil 222. High frequency electrical energy produced by the shaper 260 high-frequency energy, for example, has a frequency of from 1 to more than ten MHz.

The primary coil 222 is installed coaxially with the primary samaritane coil 224 and can be magnetically linked to the primary samaritane coil 224 through electromagnetic induction. The primary coil 222 delivers the high-frequency electric energy issued from the driver 260 high-frequency energy in the primary samaritano coil 224 through electromagnetic induction.

As secondary samaritana coil 112 is electrically powered vehicle 100, primary samaritana coil 224 is a coil LC resonance with open (unconnected) opposite ends and transmits electrical energy to an electrically powered vehicle 100, resonating with secondary samaritane coil 112 is electrically powered vehicle 100 through the electromagnetic field. Capacitive component of the primary samaritane coil 224 is also the parasitic capacitance of the coil, however, can be provided is a capacitor, attached at both ends of the coil. The coils of the primary samaritane coil 224 is also configured so as to have a large value of Q (e.g. Q>100), a greater degree of connectivity κ, and the like, based on the distance from the secondary samaritane coil 112 is electrically powered vehicle 100, the resonance frequency of the primary samaritane coil 224 and the secondary samaritane coil 112, and the like.

Primary samaritana coil 224 and the primary coil 222 forming unit 220 of the power transmission shown in figure 1. Light-emitting units 230 and block 240 connection has already been described with reference to Figure 1. Sensor 272 voltage detect voltage VS to be issued from the driver 260 high-frequency energy, and gives detektirovanie value in the ECU 270. The sensor 274 detects the current shock IS issued from the driver 260 high-frequency energy, and gives detektirovanie value in the ECU 270.

ECU 270 receives the activation command from an electrically powered vehicle 100 through the block 240 connection and activates the device 200 outlets. ECU 270 accepts the command of radiation to the light-emitting units 230 of the electrically powered vehicle 100 through the block 240 communication and illuminates the light-emitting units 230. ECU 270 accepts the command supply of electrical energy from the electrically pitamah the vehicle 100 through the block 240 connection and controls the output of the shaper 260 high-frequency energy thus to the electric energy supplied from the device 200 power to electrically powered vehicle 100 has reached the target value.

Additionally, the ECU 270 transmits information about electric power on the device 200 outlets, which includes the detected values for the voltage VS from the sensor 272 voltage and current IS from the sensor 274 current to electrically powered vehicle 100 in block 240, as well as the reception signal during the control of induction of electrically powered vehicle 100 through the block 240 connection. During the reception signal during the control over the ECU 270 controls the output of the shaper 260 high-frequency power to issue prescribed electric power smaller than the electric energy while the power supply in response to the command supply of electrical energy.

11 depicts a block diagram of the sequence of operations of the method, illustrating the control over the vehicle performed by the device 180 controls an electrically powered vehicle 100 and the ECU 260 of the device 200 outlets. The sequence of operations shown in the flowchart of the operational sequence of the method is performed at equal intervals of time, or when it is satisfied the prescribed condition.

With SS is the LCA figure 11 in an electrically powered vehicle 100, the device 180 management determines whether or not the operation mode of the vehicle mode charging (step S10). During the regime without charge, i.e. during transportation mode (No at step S10), the device 180, the control goes to step S120, without performing the remaining operations.

If in step S10 it is determined that the operation mode is a mode charging (Yes in step S10), the device 180 control establishes a connection between the block 130 vehicle communication unit 240 of the communication device 200 outlets, and sends the activation command to activate the device 200, the power to the device 200 power via the power connection 130 (step S20). Then, if there is a query radiation to a light-emitting units 230 installed on the unit 220 of the power transmission device 200 power (Yes at step S25), the device 180 transmits the control command of radiation for emitting light emitting units 230 to the device 200 power via the power connection 130 (step S30). Then the device 180 control transmits a signal during control of induction, indicating that executes control over the vehicle at block 220 energy transfer, the device 200 power via the power connection 130 and continues the transmission until after completion of the alignment unit 220 of the power transmission unit 110 receiving energy (step S40).

After that, the device 180 management is delivering on management guidance on the basis of image information from the camera 120 (the first management guidance) method, described above (step S50). The first control move is performed after electrically powered vehicle 100 is approaching the device 200 outlets, and block 220 energy transfer is under the body of the vehicle, so that the block 220 energy transfer can no longer be recognized on the basis of image information from the camera 120 (step S60).

When the block 220 energy transfer can no longer be recognized on the basis of image information from the camera 120 (Yes at step S60), the device 180 management evaluates the distance between unit 220 of the power transmission unit 110 and the reception power on the basis of information about electric power (output voltage and current of the device 200 power)transmitted from the device 200 outlets, in the manner described above. Then the device 180 performs control management guidance based on the information about the distance, estimated on the basis of the conditions of supply of electric energy from the block 220 energy transfer in block 110 receiving energy (the second management guidance) (step S70).

During the second control pointing device 180 control determines have become or not the distance between the block 220 power transmission and reception unit 110 energy minimum distance, on the basis of the differential value of the distance between the block 220 transmission EN is rgii unit 110 and the reception energy, in the manner described above (step S80). If it is determined that the distance between the block 220 power transmission and reception unit 110 energy was minimal distance (Yes at step S80), the device 180 controls makes the vehicle stop and activates the electric Parking brake (step S90).

After that, the device 180 transmits the control command to supply electric energy for the actual supply of electric energy from the device 200 power to electrically powered vehicle 100 to the device 200 power via the power connection 130 (step S100). In addition, the device 180 includes the main relay SMR2 system and actuates the Converter 142 DC/DC, and performs control of charging 150 energy storage (step S110).

In the device 200 power supply, if the block 240 connection receives the activation command transmitted from the electrically powered vehicle 100 (Yes at step S200), the ECU 270 activates the device 200 power (step S210). Then, if the block 240 communication takes command of the radiation transmitted from the electrically powered vehicle 100 (Yes at step S220), the ECU 270 illuminates the light-emitting units 230 (step S230). Then, if the block 240 connection accept signal during control of induction transmitted from the electrically powered vehicle 100 (the and on stage S240), ECU 270 controls the output driver 260 high-frequency power to issue a pre-defined electrical energy less than the charging time (step S250).

During the reception signal while operating the mouse, the ECU 270 passes detektirovanie value for the voltage VS from the sensor 272 voltage, which indicates the voltage issued from the device 200 outlets, and detektirovanie value for the current IS from the sensor 274 current, which indicates the amount of current provided by the device 200 outlets, as information about electric power on the device 200, the power to electrically powered vehicle 100 through the block 240 connection (step S260).

Then, if the block 240 communication takes command of the supply of electric energy transmitted from the electrically powered vehicle 100 (Yes at step S270), the ECU 270 controls the output of the shaper 260 high-frequency energy, for issuing energy charging to charge the vehicle (step S280).

As described above, in the present embodiment, Parking management electrically powered vehicle 100 is performed in two stages. In the first stage, the mutual position between the block 220 power transmission unit 110 and the reception power is read on the basis of image information from the camera 120, Zack is uchennai in the vehicle, and the vehicle is controlled so that it was directed at block 220 of energy transfer on the basis of the read result (the first management guidance). In the second stage, the distance L between unit 220 of the power transmission unit 110 and the reception power is read on the basis of the conditions of supply of electric energy from the block 220 energy transfer in block 110 receiving energy. Then, when the vehicle approaches the block 220 energy transfer so close that unit 220 energy transfer is under the body of the vehicle and the camera 120 can no longer capture the image block 220 power transmission, the vehicle is controlled so that the block 220 energy transfer was not aligned with the block 110 of the reception power on the basis of the information about the distance between the block 220 power transmission and reception unit 110 of energy, matter on the basis of the conditions of supply of electric energy from the block 220 energy transfer in block 110 receiving energy (the second management guidance). Essentially, the alignment unit 220 of the power transmission device 200 power supply unit 110 receiving energy concluded in the vehicle, can be carried out without the provision of bulky equipment. Therefore, according to the present invention, the power supply system for vehicle 10 may be a wasp who Astley simple design along with the that ensures accuracy Parking in relation to the device 200 outlets.

In the embodiment described above, controls the hover on the basis of image information (the first control hover), when the distance between the device 200 outlets, and electrically powered vehicle 100 is large, and management guidance based on the information about the distance, which requires the transfer of electrical energy from the block 220 energy transfer (second management guidance) is performed after the distance between the device 200 outlets, and electrically powered vehicle 100 becomes smaller. Additionally, the output electric energy from the block 220 energy transfer during the second control of induction is less than the output of electrical energy once initiated power management. Therefore, according to the present invention, power consumption can be restrained.

In the embodiment described above, the device 200 power supply is activated in response to a command from the electrically powered vehicle 100, which receives electrical energy from the device 200 outlets, and light-emitting units 230 emit in response to a command from the electrically powered vehicle 100. So the WMD under this option the implementation of the excessive consumption of electric power can be suppressed, while the vehicle is not charging.

Although switching from the first control guidance on the basis of image information from the camera 120 to the second management guidance based on the information about the distance occurs when the block 220 energy transfer is included in the dead zone of the chamber 120, in the embodiment described above, the switching from the first control move to the second control guidance can be performed when the vehicle is within a predefined distance from block 220 energy transfer. For example, the distance that provides unit 110 receiving energy the opportunity to take electrical energy from the block 220 transmit power may be set as a predetermined distance.

Although information on electric power on the device 200, the power is transmitted to the electrically powered vehicle 100, and the distance information is formed on the side of the vehicle on the basis of information about electric energy, in the above description, the distance information may be formed on the side of the device 200 outlets, and then transferred to an electrically powered vehicle 100 on the basis of the output current in the device 200 outlets or through the m transmit the received voltage on the vehicle with electrically powered vehicle 100 to the device 200 outlets. Alternatively, the device 200 outlets may have information about the distance and to determine whether it was or not completed the second management guidance, based on the information about the distance.

Although the accelerator and brake are controlled by the driver while the first control point and automatically managed by the second management guidance in the above description, the accelerator and brake can also be automatically controlled in the first control guidance, or also can be controlled by the driver while the second control guidance.

Although the camera 120 is provided in the rear of the vehicle in the above description, the place where you installed the camera 120 is not limited in the rear part of the vehicle.

Although electrical energy is transmitted from the device 200 transfer energy to an electrically powered vehicle 100 contactless manner by a resonance in the above description, the method of energy transfer from the device 200 transfer energy to an electrically powered vehicle 100 is not necessarily limited to the resonance. Can be applied to other non-contact methods of energy transfer, such as power transmission using electromagnetic induction and transfer of energy using microwaves. Besides these the way the mi energy transfer distance between the power transmission unit and the reception energy can be estimated on the basis of the conditions of supply of electric power from a drive power for the vehicle.

Although the position and orientation of block 220 of energy transfer are recognized through image recognition on the basis of light-emitting units 230 in the above description, the shape and the like of block 220 of energy transfer can be recognized by image recognition without providing a light-emitting units 230. By providing the light-emitting units 230, as in the embodiment described above, the position and orientation of block 220 of energy transfer can be detected even at night.

Although electrical energy is transmitted through the resonance pair samaritanship windings in the above description, vysokoelastichny a disc made from a material with a high dielectric constant, can be used instead of samaritanship windings as a resonator.

Although the car with series/parallel hybrid drive, capable of dividing the mechanical energy of the engine device 176 177 fission energy for transmission of the resulting energy to the drive sprocket 178 and the motor-generator 172, described as an electrically powered vehicle in the above description, the present invention is also applicable to hybrid vehicles of other types. That is, the present invention is, for example, is also applicable to so-called is the truck with serial hybrid drive, which uses the engine only 176 to actuate the motor-generator 172 generates the driving force of the vehicle when the engine-generator 174, hybrid vehicle in which only regenerative energy from the kinetic energy produced by the motor 176, is recovered as electric energy, hybrid vehicles, with the assistance of the electric drive in which the motor is used for basic mechanical energy, and the drive contributes to the engine as needed, and the like.

The present invention is also applicable to an electric vehicle, which does not include the motor 176, but moving only electric energy, and the vehicle fuel cell comprising the fuel cell in addition to the device 150 energy storage as the source of DC power. The present invention is also applicable to electrically powered vehicle, which does not include the inverter 162 with increasing voltage, and electrically powered vehicle, which does not include the inverter 142 DC/DC.
