PCT No. PCT/DE98/00454 Sec. 371 Date May 12, 1999 Sec. 102(e) Date May 12, 1999 PCT Filed Feb. 17, 1998 PCT Pub. No. WO98/40252 PCT Pub. Date Sep. 17, 1998Windshield wiper mechanism and method for precisely placing a wiper in each reversing position during wiper operation. The local wetness conditions on the windshield after deactivating the motor are taken into account from braking until reaching the reversing positions. The mechanism also includes a pulse generator for generating pulses as a function of the wiper movement, with these pulses being supplied to a controller via a signal input in order to control the motor. The pulses characterizing deceleration of the wiper from the time the motor is deactivated prior to a reversing position until it comes to a standstill are counted by a counter. The controller emits a switching signal for deactivating the motor and/or for reversing its direction of rotation prior to reaching the next reversing position or parking position as a function of the counted deceleration pulses.
