METHOD AND DEVICE FOR CONTROLLING A VEHICLE WINDSCREEN CLEANING SYSTEM

摘要

The proposed method involves setting the period of the intermittent action of the windscreen wiper blades or washer by means of a control lever. This is done by determining and recording the period between the two most recent actuations of those units; a longer period of action for, for example, the windscreen wiper blades is set by briefly switching the control lever to "stand-by" mode. Once the predetermined stand-by period has elapsed, the operating period for the windscreen wiper blades is reset on the basis of the two actuations mentioned above; the first of these following the stand-by period consists of one or more complete oscillating movements whose number is limited by switching the operation of the windscreen wiper blades to stand-by mode. In the on-board control unit for the windscreen cleaning system, the buttons for actuating the windscreen cleaner and washer and the buttons for switching the windscreen wiper and washer to stand-by mode are configured in pairs in such a way that they can be pressed simultaneously by the driver with one finger.
