Patent ID: 6967451

Claim:
A door opening and closing apparatus for a vehicle comprising: means for moving a motor by a current in accordance with a moving speed of the door to thereby generate an operating torque to open or close the door; means for detecting a griping of an operator's hand at a door knob portion in the door; means for detecting a moving amount of the door; and means for detecting a pinching of an obstacle by comparing the current and a current threshold which is set in accordance with the gripping and the moving amount; wherein in a case that a non-grip state where the door knob portion is not gripped is detected after a grip state where the door knob portion is gripped as well as that the moving amount of the door in said non-grip state is less than a predetermined value, a detection of the pinching is executed based on a second current threshold which is higher than a first current threshold for the non-grip state.
