Patent

CA 2675410

A control device for an electrically driven door is provided that can enhance the sensitivity of detection of a door pinch state and prevent a passenger from being pressed when the door pinch state occurs. The control device includes a driving force instruction value producing unit that outputs a driving force instruction value of the electrically driven door, a state observing unit that estimates a mechanical resistant force to a door driving system, a reference model that determines a dynamic characteristic of the electrically driven door to the mechanical resistant force estimated by the state observing unit, a gain compensator that computes a control compensation value that makes an output of the reference model coincide with an actual speed of the electrically driven door; and an adder that add the control compensation value computed by the gain compensator to the driving force instruction value outputted by the driving force instruction value producing unit.
