ABSTRACT:
A throttle valve control device having a traction control system includes a first control system which controls a throttle valve in accordance with movement of an accelerator pedal, a second control system which, upon a traction control of the vehicle, enforcedly pivots, with an aid of an electric motor, the throttle valve in a direction to reduce its open degree. An accelerator position sensor issues a first signal which represents the operation position of the first control system and an actuator position sensor issues a second signal which represents the operation position of the electric motor. A first device derives a first open degree of the throttle valve from the first signal and a second device derives a second open degree of the throttle valve from the second signal. A third device selects the smaller of the first and second open degrees of the throttle valve. The second control system is operated in accordance with both the second signal and the selected smaller open degree of the throttle valve.
