Abstract: Provide is a wiping device that wipes off rainwater from a wiped surface by reciprocating a wiper blade by a power source. The wiping device includes a drive part that drives a power source; and an operation part that outputs an operation signal specifying a standby position of the wiper blade to the drive part.

Abstract: A motor control device which controls a motor having an output shaft includes a vehicle speed detection part and a driving control part. The vehicle speed detection part detects a vehicle speed, which is a traveling speed of a vehicle mounted with the motor. Based on the vehicle speed detected by the vehicle speed detection part, the driving control part performs control of switching between a first driving mode which drives the motor, and a second driving mode in which a number of revolutions of the output shaft and an output of the motor are higher than in the first driving mode.

Abstract: A wiping device wipes off rainwater on a wiped surface by reciprocating a wiper blade using a predetermined power source. The wiping device includes: a drive circuit, driving the power source, and a control part, controlling the drive circuit. The control part switches a wiping range at an upper reversal position of the wiper blade.

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.
