1. A wiper motor control (135) for controlling a wiper motor (130) that moves a wiper arm (120) in a pendulum motion between two turning positions (WL), said wiper motor control (135) configured to control a speed of the wiper arm (120) dependent on a position of said wiper arm (120), characterized in that the speed of the wiper arm (120) in turning regions (WB), which comprise the turning positions (WL), follows a specified progression (210, 310, 320) independent of the speed of the wiper arm (120) between the turning regions (WB), wherein the wiper motor (130) is coupled to the wiper arm (120) by a crank mechanism (125) and the wiper motor control (135) is equipped to maintain the rotational speed of the wiper motor (130) constant while the wiper arm (120) is situated in one of the turning regions (WB), and the rotational speed of the wiper motor (130) between the turning regions (WB) is maintained constant at a lower speed than in the turning regions (WB).
