ABSTRACT:
A wiper apparatus includes: a wiper blade driven by a motor; and a wiper blade driven by a motor. The motors are drive-controlled by control microcomputers, respectively. The control microcomputers are connected to each other through a communication line. While exchanging position information of the wiper blades through the communication line, the control microcomputers synchronously drive the motors on the basis of a position relationship between both of the wiper blades. In the case where a communication abnormality occurs when the position relationship between the wiper blades is in a normal state, the wiper blade is stopped after reaching a lower turning position. In the case where the communication abnormality occurs in a state where the position relationship between the blades is inverted, the blade is stopped after reaching an upper turning position.
