ABSTRACT:
A system for controlling the power window regulators of at least the doors on the driver and front-seat passenger sides of a vehicle includes control switches having settings corresponding to at least the fully and partly open and closed positions of the windows. The control switches provide electric control signals corresponding to the switch settings. The regulator control system also includes at least one electric control motor and a motor control system which controls the motor in dependence upon the control signals received from the switches. The signals are coded in correspondence to the switch settings, for example, by differing voltage levels, and are supplied along a minimum number of wires (optimally a single wire for all the switches corresponding to each motor) to a decoder in the motor control system. The regulator control system is advantageous in the elimination of the plurality of wires previously required for individually connecting each switch position to the motor control system.
