Abstract

Based on the vehicle kinematical theory, the relationship between road speed and driving resistance of a vehicle with the speed and torque of an engine was analyzed, then, the speed and torque of the powertrain system corresponding to driving cycle was obtained. Numerical models of ICE, ISG, battery and transmission were established. According to backward-facing approach, fuel consumption of HEV with optimum ICE curve control strategy or electric assisted control strategy was simulated, and dynamic conditions of engine, ISG and battery were obtained. According to forward-facing approach, dynamic performance of HEV with optimum ICE curve control strategy or electric-assisted control strategy was simulated.
