Abstract： A multi-agent coordinated control method for hybrid electric vehicle (HEV) powertrain was proposed to improve the intelligent control, fuel economy and power performance of HEV. Taking the parallel HEV as prototype, agent models of parts subsystem were set up, and coordinated control framework of multiagent system was constructed. Pre-matching of assembly power was conducted according to different drive cycles. The adaptive problem of complex road condition was resolved by using intelligent active of single agent and cooperation ability of multi-agent. Simulation verification was carried out based on Cruise. The result shows that the multi-agent coordinated control strategy is valid and feasible. The HEV adapts its control model according to different drive cycles, further improving the vehicle fuel economy and power performance.
