摘要

摘要: 为提高电动汽车续驶里程，提出一种适用于前后轴采用不同轮毂电机四轮独立驱动电动汽车的再生制动控制策略。基于理想制动力分配曲线、 ECE R13法规、前后轴轮毂电机工作特性差异、前后轴载荷变化、电池工作特性等约束条件，制定了再生制动控制策略。在保证制动稳定的前提下，合理分配电机与摩擦制动力，提高轮毂电机制动力利用比例，回收更多制动能量。使用MATLAB/Simulink和CarSim软件联合仿真，与典型控制策略在不同制动工况下进行对比研究。仿真结果表明：新型控制策略适用于前后轴采用不同轮毂电机的四轮独立驱动电动汽车，比传统控制策略回收更多制动能量，且制动稳定性较好，有效地延长了电动汽车续驶里程。

Abstract: To increase the continuous driving mileage, a new regenerative braking control strategy of four-wheel-drive electric vehicles of different in-wheel-motors was proposed. The new control strategy based on constraint conditions for the ideal braking force distribution, ECE R13(Economic commission of europe regulations 13), the different characteristics of the in-wheel-motor and load variation in the front and rear shafts, the characteristics of the battery. Under the condition of stability braking performance, the vehicle's motor and friction braking force can be distributed reasonably, and enhance the utilization factor of in-wheel-motor to recapture more braking energy. A simulation model was built up with the software MATLAB/Simulink and CarSim, and the braking performances were simulated and compared of different braking conditions and control strategies. Simulation results show that the proposed strategy is applicable to four-wheel-drive electric vehicles of different in-wheel-motors and can receive more braking energy comparing with typical strategy, and it has a good performance of braking stability and can obviously improve the driving mileage of electric vehicles.
