An optimization method of a shifting strategy for a hybrid electric vehicle (HEV) is proposed in this article. Firstly, the basic idea of the shifting strategy is introduced. Then the differences of powertrain between a parallel HEV and fuel vehicle are analyzed, and a design method of the shifting strategy for parallel HEV is proposed. Finally, the whole vehicle simulation model is established by using Matlab/Simulink software, and the results are compared with the shifting strategy of fuel vehicles. The simulation results show that the fuel economy of the parallel HEV is significantly improved.
