Abstract

In order to simultaneously improve the fuel economy and vehicle performance of plug-in hybrid electric vehicle (PHEV), the configuration of P0 and P3 was selected as the research object. Through the configuration analysis of hybrid electric vehicle, the feasible working mode of PHEV with P0 and P3 configuration was determined. The rulebased CD-CS control strategy was further formulated, and the key model of PHEV vehicle power system was established in MATLAB/Simulink, and the fuel saving potentials of P0 and P3 double motor configuration and P3 single motor configuration were analyzed by three sets of WLTC cycle conditions. The simulation results show that the vehicle model is reasonable and the proposed vehicle control strategy has a good control effect of vehicle. Compared with the fuel vehicle, the PHEV with P3 configuration saves fuel by 55.2% and the PHEV with P0 and P3 configuration saves fuel by 66.3%, and the fuel economy improves significantly after the introduction of motor.
