  • Engine control apparatus for vehicle speed
    Patent number: 4472777
    Abstract: This specification discloses an engine control apparatus to limit engine speed. Various sensors can be used to generate electrical signals which are processed by logic means to generate a signal to limit engine speed. There is thus provided an additional safeguard against uncontrolled vehicle acceleration. Typical sensed operating conditions used to determine the need for an output limiting engine speed include engine speed, vehicle speed, throttle angle position, engine load and a brake sensor.
