ABSTRACT:
Automobile speed control to maintain actual automobile speed at a desired automobile speed, in which a superposed electrical analog signal formed by a first electrical signal indicating actual automobile speed and a feedback signal indicating fuel injection duration in an engine of an automobile is supplied to a comparator which compares it with a second electrical signal indicating desired automobile speed and memorized on a capacitor. The differential signal or error signal at the output of the comparator circuit is supplied to a servomotor which controls the position or opening of a throttle valve of the engine. The feedback signal is supplied from an injection time signal generator circuit which, in response to a fuel injection command signal from an electronic fuel injection control device associated with the engine, generates an electrical analog signal corresponding to fuel injection duration.
