Abstract
A wiper system performs operation control on wiper driving electric motors and based on position information about wiper blades and attached to pivot shafts, wherein a learning mode in which a position of the wiper blades is learned to correct blade position information is executed after the wiper blades are attached to the pivot shafts, respectively. In the learning mode, the wiper blades are moved to a prescribed position such as a lower retracted position, and that the wiper blades are located in the prescribed position is detected by such means as a sensor, a video image, and contact with a jig. If the wiper blades are detected to be in the prescribed position, the blade position information is corrected to a value corresponding to the position.
