ABSTRACT:
A device for controlling the throttle valve of an internal combustion engine accepts input signals representative of vehicle velocity, gearshift position and roadway temperature which by logic means generates a first signal which is employed to modify a second signal received from a desired value generator which is under the control the gas pedal, the signal so modified being employed to control the throttle valve or injection pump position for the internal combustion engine wherein at idling speeds a large change in the accelerator pedal position effects a small change in the throttle valve position which control changes to effect an increasingly degressive transfer characteristic wherein a small change in accelerator pedal position effects a large change in throttle valve position as the vehicle velocity increases to a high velocity.
