Patent ID: 8232754

Claim:
A control device of an electrically driven door opened or closed by an electric motor, the control device comprising: a driving force instruction value producing unit that outputs a driving force instruction value of the electrically driven door; a door driving mechanism that drives the electrically driven door on a basis of the driving force instruction value output from the driving force instruction value producing unit; a state observing unit that estimates a mechanical resistant force to the door driving mechanism; and a door pinch detecting unit that detects a door pinch state when the mechanical resistant force detected by the state observing unit exceeds a specified value wherein the door pinch detecting unit detects the door pinch state when a value obtained by subtracting a previously set offset value from the mechanical resistant force of the door driving mechanism estimated by the state observing unit exceeds a specified value or a state where the value exceeds the specified value continues for a specified time.
