Abstract
A vehicle multiplex system includes a controller and a number of remote stations connected to the controller by a control bus. The controller receives multiplexed signals indicative of the desired operation of loads such as headlamps and motors. In order to obtain reduced intensity headlamp operation or reduced speed of a continuous DC motor, the controller automatically connects and disconnects the headlamp or motor and a DC power source with a selected duty cycle. The period of repetition is sufficiently small to prevent perceptible flicker or fluctuation in motor speed. In this way, headlamp intensity and motor speed can be varied as desired, without increasing the hardware requirements of the system.
