英文摘要：

The four characteristics （rotate speed, torque, power and efficiency） of HEVs are analyzed in this paper. Based on the analysis of the characteristics of the hybrid propulsion system, the process for multi-objective optimization matching is proposed. A parameter optimization model for system matching was established and adopted in parameter matching of the hybrid power system of a specialty vehicle. Experiment results of a prototype vehicle show that the matching method can make vehicles to have better performance. An important reference is provided for further study on characteristic analysis and system matehing of hybrid power vehicles.
