ABSTRACT:
Automobile speed control system to maintain actual automobile speed at a desired automobile speed, in which a first electrical signal indicating actual automobile speed is compared with a second electrical signal indicating desired automobile speed in a comparator circuit to obtain an error signal indicating the difference between actual and desired automobile speeds. The error signal is supplied to throttle valve control means to shift a throttle valve into a position at which actual automobile speed equals the desired automobile speed. A superposed signal, consisting of the first electric signal and a negative feedback signal substantially indicating throttle valve position, is applied to a memory capacitor which provides the second electrical signal. Rememorization of the capacitor is controlled by a set switch through a memorization control circuit. The desired automobile speed level to be memorized on the capacitor is controlled by closure duration and closure repetition of the set switch.
