Abstract
A power drive system for opening and closing the sliding side door of a van type vehicle includes an inclination detector controlled control circuit for adjustably regulating the closing force applied to the door in approximate proportion to the inclination of the vehicle to provide sufficient power to close the door when the vehicle is parked on an uphill grade while providing a reduced amount of power to close the door when the vehicle is on level ground.
