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.

1. A method for controlling a moving speed of a door in an opening direction for uncovering an opening portion defined in a vehicle body and in a closing direction for covering the opening portion comprising the steps of:turning on a switch for slidably moving the door in the opening direction;driving a driving means for driving the door to be moved in the opening direction;determining whether or not the door being moved in the opening direction by the driving means is positioned in a decelerating area or beyond the decelerating area;determining whether or not the door is in contact with the vehicle body when the door is positioned in the decelerating area or beyond the decelerating area; andcontrolling the moving speed of the door to change a first predetermined speed to a second predetermined speed which is lower than the first predetermined speed before the door comes in contact with the vehicle body. 2. A method for controlling the moving speed of the door in the opening direction according to claim 1, further comprising the steps of:stop driving the driving means from driving when the door comes in contact with the vehicle body, wherein movement of the door in the opening direction is stopped. 3. A method for controlling the moving speed of the door in the opening direction according to claim 2, wherein the vehicle body is provided with at least either an entirely opening stopper or an intermediate stopper, the entirely opening stopper comes in contact with the door when the door is positioned at an entirely open position for uncovering the opening portion defined in the vehicle body, the intermediate stopper takes various postures relative to the door in response to an opening amount of a window member, and comes in contact with the door when the door is moved in the opening direction with the window member being left open with a predetermined opening amount. 4. A method for controlling the moving speed of the door in the opening direction according to claim 2, wherein the door is provided with at least either an entirely opening stopper or an intermediate stopper, the entirely opening stopper comes in contact with the vehicle body when the door is positioned at an entirely open position for uncovering the opening portion defined in the vehicle body, the intermediate stopper takes various postures relative to the door in response to an opening amount of the window member, and comes in contact with the door when the door is moved in the opening direction with the window member being left open with a predetermined opening amount. 5. A method for controlling the moving speed of the door in the opening direction according to claim 1, wherein the door comes in contact with the vehicle body via an obstacle being entrapped between the door and the vehicle body when the door is positioned in the decelerating area or beyond the decelerating area, wherein the moving speed of the door is controlled to be the second predetermined speed. 6. A method for controlling the moving speed of the door in the opening direction according to claim 1, wherein the second predetermined speed corresponding to the moving speed of the door is sufficiently low for preventing an unexpected contact of the door with the vehicle body. 7. A method for controlling the moving speed of the door in the opening direction according to claim 1, further comprising the steps of:determining whether or not an obstacle is being entrapped between the door and the vehicle body when the door is positioned ahead of the decelerating area; andcontrolling the moving speed of the door to be the first predetermined speed when the obstacle is not entrapped between the door and the vehicle body. 8. The method for controlling the moving speed of the door in the opening direction according to claim 7, further comprising the steps of:controlling the door to be moved in the closing direction for covering the opening portion defined in the vehicle body when the obstacle is entrapped between the door and the vehicle body.
