Abstract
An automobile speed control system which is capable of running at a speed which is the same as the desired memorized speed and which will be maintained constant even during momentary voltage interruptions in the system, is comprised of a discharge device such as a diode which is arranged between one end of a grounded capacitor in an integrating circuit and a line which supplies a voltage higher than that of said one end of the capacitor when a voltage power source is normal. When the voltage of the voltage power source drops, the terminal voltage of the capacitor decreases slowly and the electric charge of the capacitor is discharged. When the voltage of the voltage power source rises again, the circuit operates in the same manner as the operation thereof when the power switch is closed and the memorized automobile speed is not changed from the prior memorized speed.
