The invention discloses a multi-objective optimization fuel cell hybrid electric vehicle energy double-fuzzy control method, and relates to the technical field of new energy vehicle energy management. The method comprises the following steps: S1, establishing a fuel cell hybrid electric vehicle energy management model based on double fuzzy control, a main fuzzy controller taking the output power of a fuel cell as the output, and an auxiliary fuzzy controller taking the output power of a power cell as the output; s2, establishing a multi-objective function for optimization calculation, wherein the multi-objective function comprises an equivalent energy consumption model based on three energy sources and an equivalent performance degradation model based on two energy sources; and S3, adopting an improved non-dominated sorting genetic algorithm, and optimizing the double-fuzzy controller in the step S1 based on a Pareto multi-objective optimization method. According to the method, the complexity of fuzzy control strategy design can be simplified by formulating the multi-objective optimized energy management double fuzzy controller for the three-energy-source fuel cell hybrid electric vehicle.
