<p>A vehicle having a number of electrical components, particularly in the driver's door (3), with the electrical components powered by the main DC power contained in the main body (7) of the vehicle. A number of relatively low power DC components (35,36) and relatively high power DC components (31,32) are in the door, with a main multiplexing unit located in the main vehicle body and a remote multiplexing unit (30) electrically connected to the main multiplexing unit but located in the door, the two multiplexing units being electrically connected together by wiring extending across the hinge gap. A low power control unit (42) is also located in the door controlled by the remote multiplexing unit, the DC power to the low power components being directly supplied through it through wiring totally contained in the door, while the DC power to the high power components is directly supplied from the main multiplexing unit in the vehicle body through the wiring extending across the hinge gap. Additionally at least two reversible DC motors (31,32; 35,36) are in the door, with a maximum of three electrical wires connected to the motors, a common wire connected across one side of each of the motors, and two separate isolated wires connected to the other sides of the motors, all three wires being connected to one of the multiplexing units, DC power being supplied independently to the DC motors through the common wire and one of the two isolated wires, the polarity of the common wire determining the direction of movement of the powered motor. A number of logic rules are programmed into the system to establish a series of precedent actions.</p> |
