Abstract
A point value corresponding to a load state of an electric motor is set. The load state of the electric motor is detected so as to calculate a load point value of the electric motor and accumulate the load point values (SS). A wiper-device operation mode is identified (S). A difference Ptd between the accumulated load point value for forward operations and the accumulated load point value for return operations is compared with a criterion threshold value SVb (S). When the difference Ptd exceeds the criterion threshold value SVb, it is determined that a vehicle is in a high-speed running state. Then, an angle of rotation of the electric motor is reduced to narrow a wiping angle of the wiper blade (S). In this manner, an upper reversal position is set closer to a return side than a given position. As a result, overrun caused by the deflection of a blade or the like due to a wind generated by running when the vehicle is running at a high speed is prevented.
