Abstract
Recently, not only common types of hybrid electric vehicle (HEV) such as series or parallel but many othertypes of HEVs including 4WD hybrid electric vehicle have been developed and released. In this study, analysis of fueleconomy and driving performance for 2WD and 4WD HEV are conducted using backward simulation based ondynamic programming. To analyze the characteristics of 4WD HEV, tire slip model based on vehicle dynamics wasapplied to the backward simulation program. As a result, 2WD HEV shows better fuel economy than 4WD HEVbecause of relatively simple configuration. However, in a severe road condition, 4WD HEV shows better drivingperformance that 2WD HEV had about 6% of impossible time to follow the driving cycle though the 4WD HEV had noimpossible time.
