【Abstract】 Using ADVISOR software based on Matlab~ NFDA1 /Simulink~ NFDA1 environment as simulation platform, the effects of power train parameters and control parameters on the dynamics and the fuel economy of a parallel hybrid-electric car were studied by secondary development and modeling, and the results were verified on a hybrid-electric testing rig. The results show power train parameters have a dominant effect on the vehicle performance, and the larger the hybridization R, the better the fuel economy. Among the control parameters the battery SOC has relatively obvious effects on the fuel economy of the vehicle. Battery SOC can maintain at a certain level so long as the battery system is well matched under specific driving cycle.更多还原
