Antriebssteuervorrichtung für ein Öffnungs-/Schließelement

摘要

A drive control device for an opening/closing member may be advantageously utilized in vehicular power window systems. Occurrence of pinching of an object obstructing the path of motion of the window is detected and, upon detection of such pinching during closing, the window is moved in the opening direction for a predetermined distance to prevent serious pinching being applied to, for example, a person's hand or arm which may be blocking a power window while being closed by a vehicle driver. Closing may not be immediately resumed after pinch detection until a predetermined time period has elapsed. The pinch detection operation is effective to compensate for overrun of the window caused by a lag between the time a closing control signal is stopped and the actual motion of the window finally and completely stops.
