ABSTRACT:
A method and apparatus for finely adjusting the dwell period for an intermittent windshield wiper. A multi-position switch establishes a maximum delay and a delay request. A processor reads the switch setting and senses the timing of a positioning movement relative to the timing of the next preceding wiper blade stroke. When the elapsed time between those events is intermediate the maximum delay and the delay request, the dwell period is set equal to the elapsed time. Otherwise the dwell period is set equal to the maximum delay.
