| Abstract: | A new parallel HEV with planetary gear mechanism was introduced.The operation model region of the hybrid system was divided at the aim of achieving optimal system efficiency.Energy assignment management strategy was set up.A torque coordinated control algorithm was put forward to suppress the torque ripple during different mode switching processes.The simulation analysis of driving conditions was performed.The results show that energy assignment management strategy and coordinated control algorithm both optimize system efficiency and improve the vehicle drivability during mode-switch processes. |

| Keywords: | hybrid electric vehicle(HEV) energy assignment strategy mode-- switch coordinatedcontrol algorithm |
