Abstract
An opening-closing member controller that solves the problem includes a motor, a speed detection unit, an entrapment determination unit, and a control unit. The motor opens and closes an opening-closing member of a vehicle. The speed detection unit outputs a speed signal corresponding to a rotation speed of the motor. The entrapment determination unit determines whether entrapment of foreign material by the opening-closing member has occurred based on the speed signal. The control unit reverses or stops the motor when the entrapment determination unit determines that entrapment has occurred. The entrapment determination unit performs the determination at shorter time intervals when a remote operation switch that is separated from the vehicle is operated to close the opening-closing member than when a vehicle operation switch that is arranged in the vehicle is operated to close the opening-closing member.
