ABSTRACT:
A speed control system comprises a speed control unit and a test unit. The control unit has a Hall effect transducer for producing a signal representative of vehicle speed and a comparator for comparing that signal with a voltage reference source from which a control signal may be produced to control the vehicle throttle in the event of a disparity so as to maintain vehicle speed at a preset limit. The test unit is employed to set the voltage reference source.
