Control device at opening/closing section of vehicle and method for controlling opening/closing section of vehicle

A control device at an opening/closing section of a vehicle including a pinch determination device that is mounted to a motor for opening/closing a window of the vehicle and determines pinch of a foreign matter based on a change in a rotation number of the motor for driving to a closing direction, and demagnetization pulse applying means for supplying power whose polarity closes the window at a time when driving of the window to the opening direction through the motor is completed to the motor so that its pulse width prevents the window to move.

A method for controlling an opening/closing section of a vehicle, characterized in that in the pinch determination for determining pinch of a foreign matter based on a change in the rotation number of the motor for opening/closing the opening/closing section of the vehicle, power with reverse polarity is supplied to the motor in a pulse-like manner at a time of the completion of the opening/closing drive.

A method for controlling an opening/closing section of a vehicle, characterized in that in pinch determination for determining pinch of a foreign matter based on a change in the rotation number where a motor for opening/closing a window of the vehicle rotates to the closing direction, power with polarity whose pulse width prevents the window from moving is supplied to the motor at a time of the completion of the driving to the opening direction of the window through the motor.
