摘要:
A first judging unit integrates an increase in a corrected current when the corrected current is in a predetermined increasing state and judges that a first condition is satisfied when an integrated increase exceeds a threshold. A second judging unit integrates a decrease in door moving speed when the door moving speed is in a predetermined decreasing state and judges that a second condition is satisfied when an integrated decrease exceeds a threshold. A third judging unit integrates a decrease in motor rotation speed when the motor rotation speed is in a predetermined decreasing state and judges that a third condition is satisfied when an integrated decrease exceeds a threshold. A pinch judging unit judges whether pinch has occurred based on determination by the first, the second, and the third judging units.
