ABSTRACT:
An automatic speed control system for a vehicle includes a throttle control for controlling a throttle valve opening based on a deviation between a target speed and an actual speed of the vehicle so as to accomplish the target speed. A down-shift device for making a down-shift operation in an automatic transmission, a steady judging device for judging a steady condition of the actual speed after the down-shift operation, and an up-shift device for making an up-shift operation in the automatic transmission, when a reduction of the throttle valve opening more than a predetermined value is detected, after the actual speed is judged to be in the steady condition, are provided. A proper speed control can be provided when the vehicle runs uphill, regardless of the length and/or gradient of the uphill path.
