In series–parallel hybrid electric vehicle, the relationship between power flow and heat flow is very complex. The dynamic thermal characteristic of series–parallel hybrid electric vehicle is closely related to vehicle energy management strategy, external environment and driving conditions. In this paper, the matching of the vehicle working mode with the vehicle operating conditions is studied. The theoretic analysis of vehicle energy distribution under different typical operating condition is conducted. A coupled whole vehicle simulation model which is built in MATLAB/SIMULINK and GT suite is proposed. According to the theoretical qualitative analysis and simulation quantitative analysis, the corresponding relationship combined heat response and power consumption between power flow and heat flow is acquired. Study results show that the coupled simulation model can be effectively used in the research combined dynamic heat response, the power and heat delivery and power consumption under different operating conditions and working modes. This integrated research method combined theoretical qualitative analysis and simulation quantitative analysis is an efficient way in the multi-disciplined complex vehicle system energy management study.
