Control device and method for operating a window wiper apparatus with operating-point-dependent wiping angle adaptation

摘要

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.
