ABSTRACT:
A windshield wiper control system has a motor connected to a shaft for driving a wiper in a normal and a reverse directions. A wiper position detector includes a plurality of detector levers for providing output detection signals indicative of the position of the wiper. A storage device stores combinations of the output detection signals in a time-sequential order. A data generation device arranges the stored output detection signals from the detector, in predetermined time-sequential combinations, and prepares detection data therefrom. An indexing device compares the detection data prepared by the data generation device with corresponding combinations of stored output detection signals, and indexes the relative positions of the wiper resulting from such comparison.
