ABSTRACT:
An intermittent windshield wiper system includes a wiper control module and a wiper switch which allows an operator to set a time delay between consecutive wipes of a windshield wiper. The wiper switch includes an input setting that allows an operator to set the time delay according to the operator's needs and weather conditions. The wiper control module records the time delay and controls a wiper motor to repeatedly actuate a windshield wiper with the operator-set time delay between consecutive actuations of the windshield wiper. In one embodiment, the control module includes a timer for measuring the time delay, a memory for recording the time delay and a motor control for controlling the wiper motor. A method of controlling a windshield wiper for a vehicle is also disclosed.
