ABSTRACT:
A motor vehicle speed governor has safety features to assure that the throttle is released when the brake pedal is depressed even if malfunctions occur in certain components of the system. The speed governor has a servo for moving the throttle, an accelerator device for causing the servo to advance the throttle, a decelerator device for releasing the throttle, a control circuit for controlling the accelerator and decelerator devices in response to vehicle speed, and a power circuit that energizes the control circuit. The power circuit is connected into the brake electrical line. It includes a latching device that is powered through the ignition switch, but will latch and conduct only when energized by a set/on switch. The set/on switch requires power in the brake line across the brake fuse. The resume switch also requires power from the brake line across the brake fuse. A brake switch in the brake line is closed by depressing the brake pedal, sending a signal to the control circuit to release the throttle. A backup safety system is powered by the power circuit, but grounded through the brake light. It includes a safety release device that releases the throttle when a safety switch is opened by the depressing of the brake pedal.
