Abstract: An MCU determines whether a backlash over a predetermined value exists in a driving system including a motor and a window driving mechanism. Then, when it is determined that the backlash over the predetermined value exists in the driving system, the MCU sets the time passed from the detection of the peak of the number of rotations of the motor to a predetermined additional time as a termination time of a start cancellation period. When it is determined that the backlash over the predetermined value does not exist in the driving system, the MCU sets, as the termination time of the start cancellation period, the time when the rate of change of the number of revolutions of the motor reaches a predetermined value or the time when the rate of change of a motor input ratio reaches a predetermined value.
