The invention relates to a method for the activation of a windscreen wiper motor (20), in which the windscreen wiper motor (20) is connected via a drive shaft (21) at least indirectly with at least one wiper blade (11, 12), which moves the at least one wiper blade (11, 12) to and fro between two reversal points (UP, OP) of a wiping field (26) in differing movement direction, wherein the rotation speed and the rotation direction of the windscreen wiper motor (20) or respectively the speed (v) of the at least one wiper blade (11, 12) is detected by means of a sensor device (22) and is supplied to a control device (25) as an input value, and wherein the windscreen wiper motor (20) before reaching the respective reversal point (UP, OP) is switched off at a switch-off time (ASZ), whereupon the drive shaft (21) of the windscreen wiper motor (20); continues to rotate further by a castor angle (+-) up to its standstill, and the at least one wiper blade (11, 12) continues to move further by a trailing distance (NLS). It is provided according to the invention that the actual speed (V ist ) of the at least one wiper blade (11, 12) is compared at the switch-off time (ASZ) with a nominal speed (V soll ), and that with a difference between the actual value from the nominal value, the windscreen wiper motor (20) is operated further for a period of time ( T) which is defined in the control device (25). |
