Estimating the term…
A door speed is detected at every predetermined detecting time, and a door position is calculated at a timing detected the door speed. A target speed according to the door position is obtained by a map. A microcomputer calculates a speed difference ΔVD between the target speed and the actual or present speed, and an acceleration/deceleration value ΔVC such as the speed difference between the door speed at the last detecting time and the present detecting time. A duty increasing value and the decreasing value of a PWM duty command value for adjusting a torque of the motor are set based on the speed difference ΔVD and the acceleration/deceleration value ΔVC, the motor is driven by the PWM duty command value based on the duty increasing value and the decreasing value.
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:
An opening/closing control apparatus of an opening/closing body for a vehicle comprising:
