Abstract

An engine throttle valve operating device comprising a throttle valve operating foot pedal position detector for detecting the position of the foot pedal and producing a foot pedal position signal corresponding to the position of the foot pedal, a rapid acceleration detector connected with the foot pedal position detection for receiving the foot pedal position signal therefrom and producing a rate signal corresponding to a rate of change per unit time of the position of the foot pedal, a throttle valve actuator for actuating the engine throttle valve, a throttle valve driving signal generating circuit responsive to the foot pedal position signal and the rate signal to produce a first drive signal for operating the actuator in accordance with the foot pedal position signal when the rate of change per unit time of the position of the foot pedal is smaller than a predetermined value and a second drive signal for operating the actuator by a greater extent than under the first drive signal when the rate of change per unit time of the position of the operating member is greater than the predetermined value.
