ABSTRACT:
A cruise control apparatus includes an actuator adapted to cooperate with an accelerator to open and close an intake throttle valve to a specified opening position, and to prevent the throttle valve from returning to a fully closed position to thereby maintain a selected vehicle speed. A control unit is provided to control the actuator so that movement of the throttle valve to a fully closed position is retarded for a predetermined time period after disengaging the cruise control function. The control unit controls the actuator so as to permit free movement of the throttle valve toward the fully closed position after the predetermined time period.
