WIPER SYSTEM FOR VEHICLE WITH WINDSHIELD WASHER SYSTEM

The invention relates to a drive motor (7) for at least one brush-holding arm, intended to wipe a glass surface of a motor vehicle, the motor comprising a cam-shaped surface (35) linked in rotation concentrically with a rotation shaft of the drive motor (7), and fixed cam reading means (35) capable of cooperating with said cam (35) according to the angular positions occupied by said cam (35) to generate electrical control signals varying as a function of the angular position of the brush-holding arm on the glass surface, the cam (35) comprises a first circular conductive track (40), a second arc-shaped conductive track (42), concentric with respect to the first conductive track (40) and connected to it via a conductive bridge (44) and in that the fixed reading means are formed by three wipers (46, 48, 50) capable of entering or not entering into electrical contact respectively with the first (40) and second (42) conductive tracks and the conductive bridge (44) according to the angular positions occupied by said cam (35).
