Abstract:
An electric wiper for automobile and the control method thereof are provided. The electric wiper for automobile includes a first servomotor (1a) and a first wiper arm (2a). The output of the first servomotor (1a) is connected to a first wiper shaft (4a) through a first shaft coupling (3a). The first wiper shaft (4a) is connected to the first wiper arm (2a), which swings along with the rotation of the first wiper shaft (4a). A first position detecting apparatus (5a) is disposed on the motor shaft of said servomotor (1a). Magnetic steel (6) is disposed on said first wiper arm (2a), and a magnetic induction element (7) is disposed at the corresponding position of the automobile. Said first position detecting apparatus (5a) and the magnetic induction element (7) output a detected position signal to a first servo controller (8a). The first servo controller (8a) controls the first servomotor (1a) and forces the first wiper arm (2a) to swing. This invention has a simple structure and a low cost. It enables any swing angle of the wiper between 0 to 180 degree, the protection function of rotation-blocking, and stepless speed regulation. This invention has a high reliability and a long service lifetime.
