The invention discloses a hybrid fuel cell vehicle power optimization control method considering speed optimization. In order to improve the real-time performance of the speed optimization method, the speed optimization method based on the hierarchical framework is designed, a speed optimization upper layer module optimizes the switching boundary condition of the automobile driving mode, a speed optimization lower layer module optimizes the wheel torque distribution, the energy efficiency utilization rate is improved, and the driving energy consumption of the whole automobile is reduced. The target vehicle speed can be obtained through a speed optimization module, and therefore the expected load current can be obtained through calculation. Based on the constructed multi-objective optimization function, an adaptive factor can be calculated. Based on a state space model and an adaptive factor of a hybrid fuel cell vehicle power system, a power optimization control method based on a port Hamiltonian theory is utilized to track expected load current in real time, meanwhile, power distribution of the hybrid energy system is optimized and adjusted, and the economical efficiency, durability and comfort of the hybrid energy system are improved.
