ABSTRACT:
A motor serves to move a vehicle movable accessory. When the accessory is required to move, the motor is activated. Load on the motor is sensed. When the sensed load exceeds a reference level, the motor is deactivated. After the motor is deactivated, a device inhibits activation of the motor which induces movement of the accessory in a direction same as a direction of movement of the accessory during a period preceding the deactivation of the motor. The inhibition of activation of the motor is cancelled when the accessory is required to move in a direction different from a direction of movement of the accessory during a period preceding the deactivation of the motor.
