摘　　要： 传统纯电动汽车再生制动控制策略能量回收效率较低,制动稳定性较差,同时也简化了汽车驱动状态对于能量回收的影响。基于底盘建模的纯电动汽车制动系统,在考虑能量回收效率、汽车驱动形式、驱动强度和车辆重心位置的基础上,提出并研究了最大效率再生制动能量回收策略。仿真及测试结果表明,最大效率再生制动控制策略能够保证制动时车辆在稳定性的基础上,有效提高制动能量回收率。 By applying traditional control strategy of regenerative braking to electric vehicle, only low energy recovery efficiency and poor braking stability can be achieved, and the influence of driving conditions on energy recovery are also simplified. Based on chassis modeling of electric vehicle braking system, the maximum efficiency recovery strategy of regenerative braking energy is proposed and studied in the consideration of energy recovery efficiency, driving forms, driving intensity and the position of vehicle＇s center of gravity. As shown in the simulation and test results, the control strategy proposed in this paper can obtain improved energy recovery efficiency while ensuring braking stability.
