ABSTRACT:
An automatic speed control system for an automotive vehicle comprises a vehicle-speed sensor, a throttle actuator adjusting an opening angle of a throttle, a brake actuator adjusting a brake-fluid pressure applied to wheel cylinders, and a switching-operation decision unit controlling the switching from one of a driving-force control of the throttle actuator and a braking-force control of the brake actuator to the other. A first arithmetic circuit calculating a command signal value for the throttle actuator and a second arithmetic circuit calculating a command signal value for the brake actuator are designed to provide transition durations. The decision unit acts to continue either one or the other control executed prior to a transition for its transition duration.
