The invention relates to a wiper system with a wiper drive (), which is comprised of a wiper motor () and a gear (). A wiper arm shaft () for a wiper arm () can be driven via the output shaft () of the gear (). Linking points () for accommodating the wiper drive () on a surface () are arranged in the housing area () of the wiper drive (). The linking points () of the wiper drive () each feature a decoupling element (), in which fastening elements () to mount the wiper drive () either on a vehicle body () or on a screw-down surface () are accommodated.

Bearing for wiper drives

The control device for a wiper device of a window wiper apparatus, especially of a motor vehicle, adapts set values of the wiping angle of the wiper arm to an actually measured operating point of the wiper arm during each wiper cycle. Because of that adaptation both over-wiping and also too little wiping of a wiped area by the wiper device is at least reduced so that the wiper accuracy particularly at the turning points of the wiper arm is improved. Furthermore a method for adjusting of a set value of the wiping angle of a wiper arm of a wiper device to actually existing operating conditions or to an actual operating point is provided.
