Abstract

A vehicle door control system includes a camera disposed at a portion of the vehicle and having a field of view that encompasses a region exterior of the vehicle that is swept by a door of the vehicle as the door is opened and closed via a powered door opening/closing system of the vehicle. An image processor is operable to process image data captured by the camera to detect an object present in the region that is swept by the door when the door is opening and to determine if the door may collide with the detected object when the door is being opened. During opening of the door and responsive to determination of a potential collision of the opening door with the detected object, the vehicle door control system positions the door at a partially open position whereby a gap is established between the door and the detected object.
