ABSTRACT:
A system and method for automatically controlling a vehicle speed to a desired cruise speed for an automatic transmission equipped vehicle are disclosed in which a shift gear position range of the transmission in which the same gear ratio is charged is extended wider than a normal region determined on the basis of an opening angle of an engine throttle valve and vehicle speed during a control of the opening angle of the throttle valve to maintain the vehicle speed at a set vehicle speed so that a shift down and/or shift up which would normally occur at the same condition is not carried out.
