Research on Electric Power Coordinated Control Strategy Using Game Theory for Heavy Duty Hybrid Electric Vehicles

With the development of hybrid electric vehicles (HEVs), the problem of hybrid technology is no longer limited to the design of energy management strategy (EMS). After the EMS is determined, the difference in the dynamic response characteristics of the engine and the motor makes the actual power of the engine and the battery not meet the target power assigned by EMS. Aiming at this, this paper proposes an electric power coordinated control strategy using game theory, which takes the heavy duty HEV as the research object, and establishes a noncooperative game model. The motor and generator are regarded as participants of the game, and the working state of the battery is guaranteed by adjusting the working state of the motor and the generator. The simulation results show that the electric power coordinated control strategy can ensure that the battery follows the target power well.
