A METHOD FOR ESTIMATING MILEAGE IMPROVEMENT AND EMISSION REDUCTIONS ACHIEVABLE BY HYBRID-ELECTRIC VEHICLES

The results of two derivations relating to the fuel economy of hybrid-electric vehicles (vehicles which employ both a heat engine and electric drive system) are presented and their use is illustrated through the examples of the University of Wisconsin and TRW Systems Group hybrid-electric vehicles. The method of mileage estimation employs a specific fuel-consumption versus torque-speed map for the heat engine under study and knowledge of the hybrid-vehicle dynamics and road-load power. The method is easily extended to estimation of emission reductions through use of specific-emission- production versus torque-speed maps and is applicable to hybrid vehicles with other than electrical energy- storage systems.
