Abstract
A system is provided for fuel-efficiently operating an engine in a vehicle wherein the vehicle engine is coupled through a clutch to an infinitely variable ratio gear driving a planetary gear train. A clutch pedal actuates the clutch, and an accelerator pedal is coupled to the fuel delivery mechanism of the engine. A first storage unit is responsive to the position of the accelerator pedal and selects a stored value for the ratio of the infinitely variable ratio gear. A drive unit is provided for adjusting the ratio of the infinitely variable gear in response to the selected value from the first storage. A second storage unit is responsive to the position of the accelerator pedal and selects a stored value for a fuel delivery mechanism. A third storage unit is responsive to the position of the clutch pedal and selects a stored value for the fuel delivery mechanism. A comparison unit is coupled to the second and third storage units for selecting the smaller of the values for the fuel delivery mechanism. A drive unit is provided for adjusting the fuel delivery mechanism in response to the value selected by the comparison unit.
