Zusammenfassung: | PURPOSE:To surely detect a motor lock by distinguishing it from a normal lock at full open or full close side even if an abnormal motor lock due to gear lock, etc., is produced when an actuator is driven from its full open or full close position to a specified area, in a constant speed travel control device. CONSTITUTION:When a motor lock is detected after an actuator has been driven to a specified area, a motor is rotated in reverse direction to see whether it is moved in reverse direction or not (it is kept locked or not) to detect faulty lock (steps 2 to 12). |
