ABSTRACT:
A control device for controlling the operation of a fuel control member 17 of a vehicle engine includes a piston 12 coupled to the control member and connected to the throttle pedal of the vehicle through a lost motion spring 20. The pressure in the chambers 13, 14 defined on opposite sides of the piston can be controlled by valves so that in one mode the movement of the piston and fuel control member are directly under the control of the operator and when the vehicle is driven in a second mode, the piston controls the position of the fuel control member to provide "cruise control" and in a third mode the piston can move the fuel control member in opposition to the setting determined by the driver to provide "torque control".
