It is connect with the preset stitch of electronic control unit 101；Preset stitch is T15 stitch.
Wherein, when detecting that rear door is in the open state, rear door detection switch closure, when detecting at rear door
When closed state, rear door detection switch is opened.
It should be noted that be interaction relation between rear door detection switch 102 and rear door, when rear door is opened,
It just will drive the closing of rear door detection switch 102, when rear door is closed, just will drive the opening of rear door detection switch 102.
The course of work of each device is in Fig. 1:
When electric vehicle fault-free, rear door is closed, and rear door detection switch 102 is in the open state at this time, at this point,
The normally-closed contact of the coil no power of first relay K1, the first relay K1 is closed, the T15 stitch of electronic control unit 101
It is connected with ON grades, when car key is reached ON grades by driver, electronic control unit, electric machine controller, power battery controller
And after the completion such as instrument low pressure powers on, power battery controller controls positive and negative contactor, preliminary filling contactor completes upper high-voltage electricity behaviour
Make, and show the mark " H " of high-voltage electricity completion in instrument, car key is reached START grades again by driver, is completed to motor
Enabled, after showing that " READY " signal, driver unclamp parking brake service brake in instrument, vehicle can normally travel.
When the failures such as there are high pressures to power on when electric vehicle, power battery failure or motor, need to open at this time
Rear door repairs, at this point, rear door detection switch 102 is closed, the coil of the first relay K1 is powered, the first relay K1
Normally-closed contact open, at this point, ON grades are disconnected with T15 stitch, when car key is reached ON grades in vehicle by driver, electronics
Control unit, electric machine controller, power battery controller and instrument etc. will not low pressure power on.And then vehicle will not walk, and avoid
Driver drives vehicle to run and existing security risk when maintenance personal does not repair completion by force.
It should be noted that when rear door is opened, instrument, power battery controller, electric machine controller and other equipment
Will be identical with original working condition, the CAN bus transmission between each controller is also normal, not will receive rear door opening
It influences.
In the present embodiment, control circuit includes rear door detection switch, the first relay, the second relay and upper high-voltage electricity
Switch.By foregoing circuit, when rear door is in the open state, rear door detection switch closure, at this point, the first relay
Coil is powered, and the normally-closed contact of the first relay is opened, and ON grades disconnect with electronic control unit, even if key is screwed to by driver
At ON grades, vehicle will not go up high-voltage electricity, and then solve in the case that communication equipment damages or does not have communication equipment, dimension
It repairs personnel and driver is unable to normal communication, driver does not know about maintenance progress in the car, may drive electric vehicle by force
Walking, and then there are problems that biggish security risk.
