%X 纯电动汽车是汽车未来的发展方向，由电动机驱动，而电动机在制动过程中转化为发电机能够将部分的机械能转换为电能存储在电池中，这对提高纯电动汽车续驶里程具有重要的意义，因此有必要对纯电动汽车制动能量回收进行研究。本文对纯电动汽车的线控制动系统进行了研究，建立了整车模型、电机模型、电池模型、ESC液压制动单元模型，并确定了最大限度地实现制动能量回收控制策略。仿真结果显示，本文建立的模型及制动能量回收方法具有一定的可行性，纯电动汽车在WLTP工况下能够达到26%的制动能量率。<br />
Pure electric vehicles are the future development direction of automobiles. They are driven by electric motors, and the electric motors are converted into generators during the braking process, which can convert part of the mechanical energy into electrical energy and store them in the bat-tery, which is important for improving the driving range of pure electric vehicles. Therefore, it is necessary to study the braking energy recovery of pure electric vehicles. This paper studies the brake-by-wire system of pure electric vehicles, establishes the vehicle model, motor model, battery model, ESC hydraulic brake unit model, and determines the maximum realization of the braking energy recovery control strategy. The simulation results show that the model and braking energy recovery method established in this paper have certain feasibility, and the pure electric vehicle can achieve a braking energy rate of 26% under the WLTP condition.
