摘　　要：为高效回收电动汽车制动能量,同时保证制动强度和制动稳定性,提出了一种用于纯电动汽车复合制动的制动力分配策略,满足ECE法规对于轿车前后轴制动力分配的要求,建立Simulink和AVL Cruise的联合仿真模型,选择NEDC工况和ECE城市道路工况对电动汽车的经济性进行仿真。仿真结果表明该策略能够实现较高的制动能量回收率,提高电动汽车的续驶里程。In order to recover energy effectively in the process of regenerative braking,ensure the braking strength and braking stability,this paper proposes a braking force distribution strategy for hybrid braking of pure electric vehicles,which meets the requirements of ECE regulations for the braking force distribution of the front and rear axles. The strategy model and the vehicle model are separately established in Simulink and AVL Cruise for a co-simulation to test the efficiency of EV under the NEDC cycle condition and ECE urban circulation condition. The simulation results show that with this strategy a considerable ratio of regenerative braking energy is achieved,as well as a further driving range of the EVs.
