Based on hybrid system theory, the powertrain system of a hybrid electric vehicle (HEV) with rear wheel drive is analyzed, a control model for HEV powertrain system is built based on hybrid automaton model, and a mode-switch-based drive control strategy and a regenerative braking control strategy with braking force coordination control are proposed. Then a simulation model for HEV powertrain control strategy is set up with Simulink/Stateflow hybrid modeling method, and both performance simulation and road test on a real sample HEV are conducted. The results show that the performance of real sample HEV meets the design requirements with its fuel consumption 15.9% less than the traditional vehicle of same category under the typical urban driving cycles in China.
