Abstract
A throttle valve control system comprising an accelerator position sensor for detecting the position of an accelerator pedal, a throttle valve opening sensor for detecting the opening of a throttle valve and a control circuit for receiving the output signals of the sensors to control a reversible motor which opens and closes the throttle valve, whereby the movement of the accelerator pedal is rapidly and accurately transmitted to the throttle valve.
