ABSTRACT:
A throttle valve control apparatus for an internal combustion engine, which is high in driving safety, enabling the vehicle to cruise in an automatic manner while preventing a run-away condition of the vehicle includes a throttle valve in an intake pipe of the engine fixedly mounted on a valve shaft which is rotatably supported by the intake pipe, and a rotary disk rotatably mounted on the valve shaft and biased by a return spring to rotate relative to the valve shaft in the valve closing direction. The rotary disk is operatively connected with the accelerator pedal so that the rotary disk rotates relative to the valve shaft by operation of the accelerator pedal. A rotation-transmitting mechanism is connected between the rotary disk and the throttle lever for transmitting the rotation of the rotary disk to the throttle lever. A first actuator such as a vacuum actuator is operatively connected with the accelerator pedal for operating the accelerator pedal, independently of the driver to rotate the rotary disk in the valve-opening direction. A second actuator such as an electric motor is operatively coupled with the throttle lever through a power transmission mechanism for driving the throttle lever to rotate the valve shaft and close the throttle valve. A rotation limiter is provided for limiting the rotation of the valve shaft caused by the second actuator to a prescribed range defined by the operation of the accelerator pedal by the driver or the first actuator.
