Abstract
In a wiper device for vehicles, overrun at inversion positions is suppressed while a wind load and a high load are dealt with. A wiper device includes: a wiper blade; a wiper arm to which the wiper blade is attached; and a motor for driving the wiper arm. A load generated in the motor when the wiper blade moves on a windshield is estimated and calculated based on a motor supply current amount and the like. When an outward load generated in the wiper motor exceeds a predetermined threshold value, a high load correction process is performed based on the outward load. When the outward load is less than or equal to the threshold value, a wind load correction process is performed based on a wind load calculated from a difference between the outward load and the return load.
