ABSTRACT:
A method for controlling a wiper motor of a wiper device for a motor vehicle windshield. A control unit implements the inventive method and a wiper device for a motor vehicle windshield. The control unit controls an electric motor which powers a wiper blade on a windshield sweeping between two end-of-travel zones. In each end-of-travel zone, there is a software end-of-travel stop which is moved by a predetermined value after each passage on the software stop, the latter always remaining in its test zone, thereby providing self-adaptation of the sweeping limits in time. The invention also enables the detection of the presence of obstacles on the wiper blade path.
