Abstract: With the proposal of the current "double carbon" goal, the popularity of electric vehicles is unprecedented, especially in the application of city buses. An important means to solve this problem is to design a reasonable braking energy recovery strategy to absorb the braking energy as much as possible, so as to increase the driving range. In this paper, based on fuzzy control algorithm and multi-objective optimization algorithm, two control strategies for braking energy recovery are designed. To verify the control capability of the control strategy, built a joint simulation platform based on TruckSim-Simulink, the final results show that the two control strategies can achieve brake energy recovery, and the multi-objective optimization control strategy is better.
