摘　　要：为提高车辆经济性能,以某款纯电动汽车为例,基于ECE-R13法规制定了前后轴制动力分配方案。同时考虑到电池充放电限制和电机限制,设计了3输入1输出的模糊控制器,制定再生制动力控制策略。使用Cruise和MATLAB/Simulink联合仿真,同Crusie官方使用控制策略比较,验证策略的有效性。结果表明,所提出的控制策略是对前后轴制动力分配的优化,尤其是FTP75工况的百公里能耗减少了23.4%,延长了续航里程,为后续相关研究提供了一定参考。In order to improve the vehicle economic performance,taking a pure electric vehicle as the object,the front and rear axle braking force distribution scheme was developed based on ECE-R13 regulations.At the same time,considering the limitation of battery charge-discharge and motor,a fuzzy controller with three inputs and one output was designed,and the regenerative braking force control strategy was formulated.Cruise and MATLAB∕Simulink co-simulation were used to compare with Crusie′s official control strategy to verify the effectiveness of the strategy.The results showed that the proposed control strategy was an optimization of the braking force distribution of the front and rear axles,especially in the FTP75 operating condition,the energy consumption per 100 kilometers was reduced by 23.4%,which extended the range and provided a certain reference for subsequent related research.
