In this paper, the practical configuration of a power train for a parallel hybrid electric family sedan (HEFS) is introduced. Based on the analysis of the operation modes, an energy management strategy has been developed which can operate the engine within its high-efficiency range as much as possible and keep the battery state of charge (SOC) at a reasonable level. The components of the power unit (including engine, electric motor, battery, transmission and torque coupler) are calculated and discussed in detail according to the vehicle requirements for maximum cruising speed, acceleration time, gradeability, emission, and fuel efficiency. The simulation results show that the sedan would have performance comparable to that of a corresponding conventional sedan, about twice the fuel economy, and a range not limited by the battery storage energy.
