Abstract:
An opening/closing control method of an opening/closing body for a vehicle involving detecting a position of the opening/closing body within an opening/closing area, moving the opening/closing body and a motion speed of the opening/closing body based on a position of the opening/closing body, obtaining a predetermined target speed of the opening/closing body, controlling a feeding value for a motor moving the opening/closing body based on actual speed and the target speed, driving the motor by a torque depend on the feeding amount, the method comprising:calculating a speed difference between the actual speed and the target speed for the position of the opening/closing body at every predetermined detecting time of the motion speed; calculating an acceleration/deceleration value of a speed difference between a last detected motion speed and a present detected motion speed; setting a feeding amount increasing/decreasing value for changing the torque of the motor based on at least the speed difference and the acceleration/deceleration value; and controlling the motor by a torque depending on one of a feeding value added the feeding amount increasing/decreasing value to a last obtained feeding value and a feeding value subtracted the feeding amount increasing/decreasing value from the last obtained feeding value.
