Fuel cell automobile energy management method fused with information physical system

The invention provides a fuel cell vehicle energy management method fused with an information physical system, which not only considers energy flow and consumption in a vehicle system, but also considers the influence of future road topography and traffic conditions on vehicle energy management, and explores optimal control in a feasible region in combination with a depth deterministic strategy gradient algorithm. Therefore, discrete errors are effectively avoided, and the reliability of the strategy is improved. According to the invention, information interaction between the vehicle system and the network layer is realized through the information physical system, and future terrain information, traffic information, battery aging, fuel cell durability constraint, hydrogen consumption and the like obtained through the information physical system are incorporated into a control framework. And the method has important practical significance for realizing optimal balance between the system durability and the hydr
