The invention provides a wiper control system and method with a vehicle body control unit. The system comprises a vehicle body control unit, and the vehicle body control unit is connected with a wipercombination switch, a wiper washing motor, a wiper high speed relay, a wiper low speed intermittent relay and a wiper water wiping motor; the wiper water wiping motor is also connected to the wiper high speed relay and the wiper low speed intermittent relay; the vehicle body control unit receives the state of the wiper combination switch, controls the operation of the wiper water wiping motor through the wiper high speed relay and the wiper low speed intermittent relay according to the state of the wiper combination switch, and at the same time, and controls the operation of the wiper washingmotor according to the state of the wiper combination switch. The system ensures the consistency of wiper return positions and the return number by triggering a return signal edge, achieves the stopof the wiper through the methods of wiper water wiping motor reverse electromotive force and wiper motion friction energy consumption, and achieves the separation of a trigger signal and a return signal of a wiper intermittent mode.
Description
technical field [0001] The invention belongs to the field of wiper control, and in particular relates to a wiper control system and method with a vehicle body control unit. Background technique [0002] Wipers, also known as wipers, water dials, wipers or windshield wipers, are devices used to scrape off raindrops and dust attached to the windshield of vehicles to improve the visibility of drivers and increase driving safety. Whether the wiper working mode is normal or not has become one of the important indicators affecting the safety performance of the vehicle. The traditional wiper return mode guarantees the number of wiper return times by the number of rotations of the wiper motor at rated voltage within the rated time, and the time delay estimated according to the number of rotations ensures the return position of the wiper. In this method, the time error of the number of rotations of the wiper motor is large, and the number of rotations of the motor is greatly affecte...
