    • A wiper apparatus includes: a wiper blade driven by a first motor; and a wiper blade driven by a second 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. When an abnormality occurs in a communication state of an in-vehicle LAN, a setting state of a wiper switch is grasped through a switch signal line directly connected to the wiper switch, and wipers are prevented from being stopped when such communication abnormality occurs.
