Electro-mechanical braking force distribution strategy for electric vehicle

In order to meet the requirements of safety and enhance energy recover efficiency in braking process for electric vehicle, the principle of electro-mechanical composite braking system is analyzed in this paper, and a method for the electric vehicle braking system strategy is proposed, which combines fuzzy algorithm with desired braking force distribution strategy. By embedding the simulation model in the ADVISOR 2002 platform with safety validation and testing regenerative braking efficiency, an electro-mechanical compound braking dynamic simulation model is established. The results show that, the proposed braking force distribution strategy can improve regenerative braking efficiency 62.5% compared to original control strategy, which reaches 42.13% in CYC_UDDS driving cycle, and achieve the requirements of the safety in many conditions.
