ABSTRACT:
A system and method for automatically controlling a vehicle speed to a desired cruise speed are disclosed in which when the vehicle speed is reduced by a first predetermined value from a set and stored cruise speed at which the vehicle is cruising during the operation of the automatic cruise control, the gear range of a vehicular transmission is shifted down and simultaneously the set and stored cruise speed is updated to reduce the set and stored cruise speed by a second predetermined value so that the vehicle speed coincides with the updated cruise speed. In addition, after a predetermined time has elapsed, the gear range is shifted up and the updated cruise speed is returned to the original cruise speed.
