Abstract:
    The invention relates to an electric windshield wiper, wherein it is formed by windshield wiper controller, motor and windshield wiper executor; the windshield wiper controller comprises microprocessor (1), LIN bus interface circuit (2), driving circuit (3), signal input circuit (4), return circuit (5), and stabilize power circuit (6); the LIN receiver/sender of circuit (2) is connected to the system bus and connected to the microprocessor (1); the signal of bus via interface circuit (2) is transmitted into microprocessor (1) to be analyzed and processed to output relative control signal to the driving circuit (3); the driving circuit (3) drives windshield wiper motor in different work states, and obtains windshield wiper position signal from motor to be feedback to the microprocessor. The invention has compact structure and fewer wires, to prolong the service life by reducing the impact on motor when changing states.
