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.

An opening-closing body driving motor includes a motor body, a drive circuit, and a control circuit. The motor body is provided to automatically open and close an opening-closing body of a vehicle. The drive circuit supplies driving power to the motor body. The control circuit includes a PWM controller. The control circuit is configured to adjust the driving power by PWM control and control an operation mode of the opening-closing body through the motor body such that the operation mode is changeable. The PWM controller is configured to have a control frequency of the PWM control include a frequency in an audible range based on a predetermined trigger so that the motor body vibrates in the audible range, thereby performing a sound producing operation. The predetermined trigger includes information about an opening-closing state of the opening-closing body or information about activation and deactivation of a child lock.

A vehicle window opening device includes a controller, a change detector, and a drawing detector. The controller configured to control opening and closing of a vehicle window based on a drive force of a motor. The change detector is configured to detect a change in a state of movement of the vehicle window. A drawing detector is configured to detect drawing of a foreign matter by the vehicle window based on a change detected by the change detector. The controller is configured to restrict opening of the vehicle window after the drawing detection.

An opening-closing body is operated toward an end position of the movable range, a section where the motor application voltage is set to a fixed value defines a first section. A section set between the first section and the end position defines a second section. The controller is configured to execute speed reduction control and stop control in the second section. At a point in time when the rotation speed of the motor body becomes less than or equal to a second threshold value, in the first section or the second section, the controller sets the motor application voltage that is applied from the point in time until the opening-closing body reaches the end position and the stop control is executed to a voltage value that is greater than or equal to the motor application voltage applied at the point in time.
