Abstract
A vehicle windshield wiper control system has an electrically driven wiper motor, a wiper control switch coupled to the motor and having a delay position wherein the motor operates intermittently, a vehicle speed sensor, and a control unit coupled to the control switch, the motor, and to the speed sensor. The control operation of the motor, the control unit periodically executes a method or algorithm which causes the system to vary the dwell time between motor operations as a function of sensed vehicle speed, and optionally as a function of an operator adjustable dwell time control.
