Abstract
The invention relates to a wiper motor control for controlling a wiper motor that moves a wiper arm in a pendulum motion between two turning positions, said wiper motor control being designed to control a speed of the wiper arm dependent on a position of the wiper arm. The speed of the wiper arm in turning regions, which comprise the turning positions, follows a specified progression independent of the speed of the wiper arm between the turning regions.
Claims11
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).
A method for controlling a wiper motor (130), which moves a wiper arm (120) in a pendulum motion between two turning positions (WL), wherein the method comprises:
- Determining whether the wiper arm (120) is situated in one of two turning regions (WB), which lie around the turning positions (WL), and
- Actuating the wiper motor (130) such that a speed of the wiper arm (120) in the turning region (WB) follows a rigidly specified progression independent of a speed of the wiper arm (120) between the turning regions (WB).
