The research for power matching strategy of parallel hybrid vehicle

Power-train is a key component of the parallel electrical hybrid vehicle for which can control energy flow of the system. In this paper, according to the basic configuration of parallel electrical hybrid power-train, the control strategy based on limiting work range of engine is discussed. As a load adjusting device, the motor uptake power and maintain battery working on the range of high efficiency when the system need light torque, otherwise output power to driving system. By using simulation software, the models of engine, clutch, battery, motor, driving system and whole vehicle are established. The results of simulation show that the strategy is available.
