Abstract
Abstract A motor vehicle has a body, a door movable on the body between a closed position and an open position, an electric power source mounted in the body, and a latch having interengageable parts on the vehicle body and on the door engageable in a latched position to retain the door in the closed position, and an electrical actuator energizable to put the latch in an unlatched position. A drive on the body connected to the door is energizable from the source for moving the door between the open and closed positions and a battery is provided in the door separate from the body-mounted power source. An electronic controller in the door powered by the battery is connected to the latch actuator for operating same to unlatch the door and to a transmitter for transmitting a signal indicating the position of the door and of the latch. Another electronic controller in the body includes a receiver for receiving the signal from the transmitter in the door is connected to the drive and to the body power source for operating the drive in accordance with the signal received by the body receiver.
