Abstract

In a wiper system for vehicles, in particular for automobile windshields, including a first wiper arm, a primary drive motor (12) associated with the wiper arm for generating a defined wiping motion of the first wiper arm, at least one second wiper arm, and a secondary drive motor (13) associated with the second wiper arm for generating a defined wiping motion of the second wiper arm, the secondary drive motor (13) being controlled as a function of the position of the primary drive motor (12), a motor position code element (23) is provided, which is coupled to the primary drive motor (12) and is provided with control codes (24) that are directly representative of the associated position of the secondary drive motor (13). For scanning the control codes (24) of the motor position code element (23), a scanner unit (25) is used, which via a signal connection (22) is connected to a controller (27) of the secondary drive motor (13).
