    • A throttle valve control system comprises an accelerator position sensor for detecting the amount of operation of the accelerator, a throttle valve opening degree determining circuit which receives the output of the accelerator position sensor and determines the opening degree of the throttle valve, and a throttle valve driving device which drives the throttle valve to the position corresponding to the opening degree determined by the throttle valve opening degree determining circuit. The throttle valve opening degree determining circuit is arranged to determine the opening degree of the throttle valve with respect to the amount of operation of the accelerator so that the change in the opening degree of the throttle valve for a given change in the amount of operation of the accelerator is relatively small when the amount of operation of the accelerator is in an intermediate range and is relatively large when the amount of operation of the accelerator is above or below the intermediate range.
