ABSTRACT:
A system and method for automatically controlling a vehicle speed to a desired cruise speed includes an inhibit switch connected in parallel to a line between a power supply and a main self hold power supply switch (self-hold type) of an automatic cruise controlling system. When the vehicle speed is below a predetermined value, the inhibit switch is open so that the automatic cruise speed controlling system cannot receive power via the main, switch. Thus, wasteful comsumption of power is reduced.
