US Patent 7592896 Vehicle door control apparatus

Based on a user's instruction, a door control unit drives a door opening/closing motor for a pop-up operation. A door is thereby rotated to a predetermined angle, which is smaller than a fully opened angle. Therefore, even when a user holds stuff in his/her hands, the door can be easily opened up to the predetermined angle. When the door is opened at the predetermined angle, the user can insert a part of his/her body into a gap corresponding to the predetermined angle and then further open the door by pushing the door from the door inside surface.
