The invention relates to electric cars, in particular to devices steklosetki vehicles.

It is known device [1] automatic control DV is locatel ultrasound, installed from one side of the inner surface of the windshield and receiver of ultrasonic radiation on the other side of the windshield.

The disadvantage of this device is the use of ultrasonic vibrations, which leads to additional vibrations, as well as the complexity of apparatus used. In addition, it is unacceptable to include drive wiper without including washer glass.

It is known device [2], containing optically coupled through the glass of the two-photon-coupled pair of emitter - light receiver, and the first opto-pair controls the degree of contamination of the external surface of the glass, and the second is internal.

The disadvantages of this system of cleaning glass is its activation on the level of contamination of the glass, which can result in the process of moving to an unexpected for the driver positives wiper and as a result, the possibility of committing a road traffic accident.

The closest in technical essence of the solution is the device [3] , which contains the standard scheme wiper and connected in parallel to the automatic cleaning system glass containing sensor contamination V. the device is the cleaning system is automatically triggered on the level of contamination of the glass, such as gradually the dust or the appearance of water droplets, and, as a consequence, the unexpected happens for the driver turning on the washer glass and drive wiper. Thus, when the vehicle is moving, there is an element of surprise, which can distract the driver's attention from the immediate control of the vehicle and lead to an emergency situation. In such circumstances, the gradual contamination of the glass, it is advisable that the driver chose the moment of switching on the windscreen wipers and the mode of its operation. On the other hand, in an unexpected traffic situations, such as sudden and severe contamination of the glass passing vehicles and, as a consequence, the instantaneous loss of a driver's visibility of the road, the device should turn on immediately and automatically.

In addition, because the device works to reduce the luminous flux sensor, one night, when unexpected contamination of the glass, the useful luminous flux of the sensor decreases, but, if at this time the glass is illuminated by headlights of oncoming vehicles, the total luminous flux can be significant and dates the movement.

The solution of this problem is achieved by the fact that the system clean glass of the vehicle have been added to the second oscillator, a phase detector, a filter, a low frequency differential amplifier, comparator, amplifier, third and fourth electronic switches, and the first output of the second generator connected to the sensor input of contamination of the glass, the output of which is connected to the first input of the phase detector, the second output of the second generator is connected to a second input of the phase detector, the output of the phase detector is connected to the input of the LPF, the output of which is connected to the input of a differentiating amplifier and the input of the amplifier, the output of the differentiating amplifier through a comparator connected to the input of the third electronic switch, the output of which is connected to the first input schema matching, a second input trigger and output of the fourth electronic switch, the output of the amplifier is connected to the input of the fourth electronic switch, direct trigger is connected to the control input of the fourth electronic switch, and the inverted output of the trigger is connected to the control input of the third electronic key.

Comparative analysis with the prototype shows that the proposed system the eyes of the ora, phase detector, a filter, a low frequency differential amplifier, a comparator, an amplifier, an additional pair of electronic keys, and connections between previously and newly introduced elements. This allows to make a conclusion on compliance of the proposed solution the criterion of "novelty".

The ability of the proposed treatment system to respond to the rate of change of contamination of the glass and increase the sensitivity and noise immunity due to the use of phase detection eliminates tripping device associated with a gradual change in the level of contamination of the glass when cleaning in automatic mode there is no need. This eliminates unexpected for the driver positives purification system in the process of movement and, as a consequence, the dispersion of his attention or manifestation on his part unpredictable reactions. Cleaning system, triggered by the rate of change of contamination of the glass allows you to automatically avoid the occurrence of emergency situations, such as when a sudden contamination of glass from under the wheels of other vehicles. This allows to conclude that the criterion of "substantial excellent the transport means comprises an electric motor 1 drive brushes, motor pump washer 2, relay 3 time switch 4 kinds of work, the electromagnetic valve 5 washer, sensor 6 of contamination of the glass, the first pulse generator 7, scheme 8 matches, four electronic switches 9, 10, 18, 19, the trigger 12, the second pulse generator 11, the phase detector 13, the filter 14 is a low frequency differential amplifier 15, a comparator 16, an amplifier 17.

The output of the pulse generator 7 is connected to a second input circuit 8 matches, the output of which is connected to the input of the first electronic key 9 and the first input of the trigger 12. Direct trigger output 12 is connected to the input of the second electronic key 10 and the control input of the fourth electronic switch 19, and the inverted output of the trigger 12 is connected to the control input of the third electronic key 18.

Cleaning system glass works as follows.

In position 1 of switch 4 kinds of work included relay 3 time and the voltage supplied to the motor pump of the washer 2 and the valve 5 washer. The valve 5 is activated and the fluid from the pump is fed to the glass. Relay 3 time creates a time delay to turn off the engine 2 washer.

After actuation of the relay 3 time switch 4 kinds of work can be disabled to further the power of the engine 2 occurs through the relay contacts 3 times. In position P switch 4 operation voltage supplied to electrodyne. That is, the cleaning system is in manual mode in a standard way.

Sensor supply 6 of contamination of the glass comes from the first output of the second pulse generator 11, the output signal from the sensor 6 of contamination of the glass arrives at the first input of phase detector 13. From the second output of the second generator 11 of pulses of the reference voltage supplied to the second input of phase detector 13. The use phase detection to reduce the effects of noise and lighting sensor 6 of contamination of the glass counter vehicles. The signal proportional to the contamination of the glass, through the filter 14 low frequency, separating the double harmonic frequency of the second pulse generator 11 and reduces the ripple voltage is supplied to the differential amplifier 15 and the amplifier 17. The output voltage of the differentiating amplifier 15, is proportional to the rate of change of contamination of the glass, is fed to the comparator 16, the actuation level of which determines the critical rate of change of contamination of the glass, which releases the cleaning system.

From the output of the comparator 16 a signal through the electronic key 18 is supplied to the first input circuit 8 matches and the second and the presence of signals from the output of the comparator 16 and momentum from the first generator 7 pulses at the output of the circuit 8 matches you may receive the signal, which is fed to the input key 9. The key 9 is opened and the output signal from the key 9 is supplied to relay 3 time. Turns on relay 3 time, its contacts are closed and the voltage supplied to the motor pump of the washer 2 and the valve 5 washer.

The key 10 is opened and the voltage applied to the motor 1 drive wiper blades, which begins to work.

After a certain time delay relay 3 off the motor 2 and the valve 5 washer.

The signal from the direct output of the trigger 12 opens the electronic switch 19. When the input circuit 8 matches from the output of amplifier 17 through the open key 19 a signal proportional to the level of contamination of the glass. The signal proportional to the rate of change of the level of pollution, is cut off, as the electronic key 18 will be closed, because the inverse of the output of the trigger 12 will be low on the EIW, defined by the pulse generator 7, cleaning glass has not occurred, then the scheme 8 matches the next pulse arrives and repeats the cycle of operation of the washer. The wiper continues to operate until and unless there is a clear glass, and therefore the signal from the sensor 6 will stop the trigger 12 will tip over, the motor 1 will stop working. When dumping the trigger 12 is opened electronic key 18, and the switch 19 is closed and the cleaning system enters standby mode by the rate of change of contamination of the glass.

Thus, the device provides immediate and automatic activation of the cleaning system in case of sudden pollution of the glass of the vehicle, when the driver loses visibility of the road. The system works until, until final cleaning of glass, because in this mode the system operates on the level of contamination. If for one cycle of operation of the washer clearing has not occurred, the operation cycle of the washer is repeated. The motor 1 drive brush stops working only after the final cleaning of the glass. After cleaning the device enters the operation mode on the rate of change in pollution that ISO consideration at examination:
