Abstract
A method for the activation of a windscreen wiper motor is disclosed, in which the motor is connected to a wiper blade by a drive shaft, which moves the wiper blade between two reversal points of a wiping field in differing movement direction, where the rotation speed and direction of the motor, or the speed of the wiper blade, is detected by a sensor device and is supplied to a control device as an input value. The motor, before reaching the respective reversal point, is switched off, whereupon the drive shaft continues to rotate further by a castor angle up to a standstill, and the wiper blade moves further by a trailing distance. The actual speed of the wiper blade is compared at the switch-off time with a nominal speed, and the motor is operated further for a period of time when the comparison results in a difference in values.
