摘　　要：针对某款前驱式纯电动汽车的制动能量回收问题,文章设计了一种查表式再生制动控制策略。基于联合国欧洲经济委员会(ECE)汽车法规、I曲线以及路面附着系数为0.7的f线组的前、后轴制动力分配方法,根据加速踏板位移、制动踏板位移、车速、电池荷电状态(SOC)及制动强度这五个影响因素,设计制动能量回收控制策略。利用AVL Cruise搭建整车模型,利用Matlab/Simulink搭建制动能量回收控制策略模型,在新欧洲驾驶循环(NEDC)工况下,对所设计的制动能量回收控制策略进行联合仿真并验证其正确性。仿真结果表明,文章所设计的制动能量回收控制策略符合制动稳定性及安全性的要求,且可以进行制动能量回收,并提高电池荷电状态,制动能量回收可达18%。Aiming at the energy recovery problem of a front-drive electric vehicle, this paper proposes a braking energy recovery control strategy based on look-up table method. Based on economic commission of europe(ECE) regulations, I curve and front and rear braking force distribution method of f line group with road adhesion coefficient of 0.7, the braking energy recovery control stategy was designed according to five influencing factors including accelerator pedal displacement,brake pedal displacement, vehicle speed, battery state of charge(SOC) and braking strength. AVL Cruise was used to build the vehicle model, and Matlab/Simulink was used to build the braking energy recovery control strategy model. In the new european driving cycle(NEDC) condition, the designed braking energy recovery control strategy was jointly simulated and verified whether it will be correct.The simulation results show that the control strategy designed in this paper meets the requirements of braking stability and safety, and recovers braking energy, and improves battery SOC,Braking energy recovery is up to 18%.
