An automatic vehicle cruise control system is comprised of a vehicle-speed determining device movable between an upper limit for a high speed operation of the vehicle and a lower limit for a low speed operation of the vehicle, a motor for moving the vehicle-speed determining device, a speed-detecting device for detecting the actual speed of the vehicle, a target-setting device for setting the required speed of the vehicle, a motor driving device for driving the motor in such a manner that the actual speed can be equalized to the required speed, a main switch interposed between a battery and the motor driving device, a switch-detecting device for detecting the opening of the main switch, a switching device for assuring an electrical connection between the battery and the motor driving device and a control device for activating the switching device after the closure of the main switch and deactivating the switching device after moving the vehicle-speed determining device to its lower limit via the motor upon detection of the opening of the main switch by the switch-detecting device.
