Abstract
An apparatus and method for controlling a windshield wiping system, based on a connection threshold defined for starting operation of the windshield wiping system, a disconnection threshold defined for ceasing operation of the windshield wiping system in an intermittent mode of operation, and a disconnection threshold defined for ceasing operation of the windshield wiping system in a continuous mode of operation. The apparatus includes a sensor apparatus and a circuit arrangement. The sensor apparatus which generates a signal the value of which varies based on the degree of liquid or dirt on the windshield. The sensor signal is then processed by a microprocessor. The thresholds are defined based on the sensor signal.
