Abstract

A rain sensor, in particular for a motor vehicle including a window-wiper device (windshield-wiper device), including a measuring element, which has a sensitivity that is predefinable by a control device, a signal, characterizing the speed of the motor vehicle, being able to be transmitted to the control device, and the control device increasing the sensitivity of the measuring element at lower speed. Furthermore, a method for controlling a windshield-wiper device, in particular for a motor vehicle. A measuring element is connected to a control device, its sensitivity being predefined by the control device. A signal characterizing a speed of the motor vehicle is transmitted to the control device and the sensitivity of the measuring element increased at lower speed.
