A controller 60 controls the drive of the electric motor 21 according to the detected operation force, and assists the opening/closing action of the door to be opened/closed by operating the door handle according to the operation force. A power supply voltage supply circuit 40 closes an ignition switch IG, and supplies the power supply voltage to the controller 60 from a battery BT by opening/closing the door to enable the operation of the controller 60. The controller also receives the vehicle speed, the angle of inclination, the peripheral temperature of electric parts, the motor current and the motor voltage, and supplementally controls the drive of the electric motor 21 according thereto. |
