Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to an automobile self-adaptive rain sensor circuit. Background technique [0002] The wiper is one of the important components of the car body system. It is related to the safety of driving in rainy days. It is used to remove rain, snow, dust and muddy water on the windshield, rear window glass and headlight glass to ensure that the glass is transparent and clear. The traditional windshield wiper is made up of simple switch type control part and mechanical mechanism. The system drives the four-bar mechanism through the wiper motor with worm gear reducer, and at the same time drives the wiper blades on both sides to swing to clean the windshield. The driver manually operates the wiper combination switch to turn on the power and switch the working armature of the motor to realize the selection of the wiper opening and its working mode (fast and slow gear). ...
