ABSTRACT:
A wiper system using two wipers and two wiper motors, which drive the wipers and of which at least one first wiper motor forms a sub-assembly with an electronic control unit. The second wiper motor is a rotary motor having only one sensory system for detecting the absolute and relative rotational position of its driven shaft, which generates corresponding signals for the control unit of the first wiper motor, and the first wiper motor, in the rotational speed and the rotational position of its driven shaft, is regulated by the control unit as a function of the rotational position and the rotational speed of the driven shaft of the second wiper motor.
