摘　　要：为提高纯电动汽车的续航能力,保证车辆稳定行驶,提出一种纯电动车辆的制动能量回收控制方法。从多个角度分析纯电动汽车在行驶过程中的能量变动情况,考虑驱动力需要克服的相关阻力,根据车辆各部件的工作效率以及电池充电情况,计算车辆驱动消耗实际电量。分析纯电动汽车制动过程中的动力学以及路面的摩擦因子对制动产生的影响,明确汽车制动时产生的能量损失和影响能量回收的相关因素。为了获得最大的再生能量,在能量回收控制中,以制动的方式进行能量补偿,并将更多的动能用于动力发电机,达到制动能量的回收循环。仿真结果表明,所研究方法对制动能量的回收控制效果较好,回收利用率较为理想。In order to improve the endurance of the pure electric vehicle and ensure the stable running of the vehicle,a control method of braking energy recovery of the pure electric vehicle is proposed.Analyze the energy change of the pure electric vehicle in the driving process from multiple perspectives,consider the relevant resistance that the driving force needs to overcome,and calculate the actual power consumption of the vehicle driving according to the working efficiency of the vehicle components and the battery charging situation.Analyze the dynamics of pure electric vehicle braking process and the impact of road friction factor on braking,and identify the energy loss and related factors affecting energy recovery during vehicle braking.In order to obtain the maximum regenerative energy,in the energy recovery control,the energy is compensated by braking,and more kinetic energy is used for the power generator to achieve the recovery cycle of braking energy.The simulation results show that the research method has good control effect on the recovery of braking energy,and the recovery rate is ideal.
