摘　　要：为提高电动轮汽车制动过程中再生制动能量的回收率以达到节约能源的目的,提出了一套适用于电动轮汽车的全新构型机电复合再生制动系统及控制策略。在该控制策略中,考虑到电池SOC值和制动强度对电机再生制动力矩的影响,设计了双输入单输出的模糊控制器,并在AMESim软件平台中搭建了15自由度的电动轮汽车的整车仿真模型和再生制动系统与液压制动系统的仿真模型,在不同的制动强度下采用UDDS循环进行AMESim-Simulink联合仿真。结果表明,所制定的控制策略能满足要求,在保证制动效能的前提下实现再生制动能量的有效回收。In order to enhance the energy recovery ratio of regenerative braking in the braking process of e-lectric-wheel vehicle for saving energy, a set of electro-mechanical compound regenerative braking system and its control strategy with new configuration suitable for electric-wheel vehicle is proposed. In this control strategy, taking into account the influences of battery S0 C and braking strength on the regenerative braking torque of motor, a fuzzy controller with two inputs and one output variable is designed. Then simulation models for a 15-D0 F electric-wheel vehicle and its regenerative braking system and hydraulic brake system are established on AMESim platform,and an AMESim-Simulink co-simulation with UDDS driving cycles is conducted under different braking intensities. The re-sults show that the control strategy formulated can meet the requirements of effective recovery of regenerative braking energy while ensuring braking efficacy.
