Abstract
A door is moved in an opening direction at a first speed until the door reaches a decelerating area. A moving speed of the door in the opening direction is decelerated from the first speed to a second speed being lower than the first speed while the door has been moved in the decelerating area. The movement of the door is stopped when the door is moved beyond the decelerating area, the door comes in contact with an obstacle, and the moving speed of the door becomes lower than a predetermined speed corresponding to an open position of the door by a predetermined threshold value.
Claims10
A door apparatus for a vehicle comprising:
- a door being movable in an opening direction for uncovering an opening portion defined in a vehicle body and in a closing direction for covering the opening portion;
- a moving means assembled between the vehicle body and the door;
- and
- a driving means for driving the door to be moved, the driving means further detecting a moving speed of the door and controlling the detected moving speed of the door;
- the moving means including:
- a predetermined moving stroke in the opening direction;
- and
- a decelerating area defined within the predetermined moving stroke for decelerating the moving speed of the door,
- wherein the door is moved in the opening direction at a first speed by use of the moving means and the driving means until the door reaches the decelerating area, the moving speed of the door in the opening direction is decelerated by the driving means from the first speed to a second speed being lower than the first speed while the door has been moved in the decelerating area, and the movement of the door is stopped by the driving means when the door is moved beyond the decelerating area, the door and the vehicle body come in contact with each other via an obstacle, and the moving speed of the door in the opening direction detected by the diving means becomes lower than a predetermined speed corresponding to an open position of the door by a predetermined threshold value.
