Patent ID: 7977903

Claim:
An electrically powered door actuating system of a motor vehicle, comprising: a door actuating device that, upon manipulation of a door control switch means, moves a slide door in closing or opening direction with power of an electric motor; a contact type obstacle sensor that detects an obstacle on a given track of the door by contacting the same; a non-contact type obstacle sensor that detects an obstacle on the given track of the door without contacting the same; and a control unit that controls the door actuating device by processing information signals issued from the door control switch means and the contact and non-contact type obstacle sensors, wherein the control unit is configured to carry out: when the door actuating device is moving the door due to manipulation of the door control switch means, controlling the door actuating device to move the door in an opposite direction upon detecting an obstacle by the contact type obstacle sensor; when the door actuating device is moving the door due to manipulation of the door control switch means, controlling the door actuating device to temporarily stop the movement of the door upon detecting an obstacle by the non-contact type obstacle sensor; and when the temporary stop of the door is being kept by the door actuating device, controlling the door actuating device to keep the temporary stop of the door upon detecting an obstacle by the contact and non-contact type obstacle sensors, and controlling the door actuating device to move the door in the same direction as that in which the door moved before the temporary stop of the door upon detecting no obstacle by the contact and non-contact obstacle sensors.
