ABSTRACT:
In an accelerator control system including electrical elements or devices, if trouble occurs in these elements, the throttle valve may be kept open in spite of the fact that the accelerator pedal is fully released. To overcome the above problem, an accelerator pedal zero-stroke detector, a throttle valve initial-position detector and an abnormality signal generator are additionally provided for the accelerator control system, in order to generate an alarm signal or a system disabling signal when the throttle valve is kept open beyond a predetermined time interval after the accelerator pedal has been fully released.
