摘要
纯电动汽车机电复合制动控制所要解决的关键问题是在一定的制动需求下,如何合理的协调前、后轴制动力以及电机再生制动力三者之间的关系,使车辆既能有效地保证制动距离的安全性、制动方向的稳定性又能充分地回收制动能量。该文提出了一种基于模糊控制的机电复合制动控制策略,并将重新搭建的制动控制模块嵌入ADVISOR中进行仿真。结果表明:前、后轴制动力分配分布在设计的曲线上,满足安全要求;在CYC_UDDS循环工况下制动能量回收效率到达了43.49%,比ADVISOR自带的策略提高了67.8%,验证了该文提出的控制策略的有效性和可行性。
The key problem of pure electric vehicle with electro-mechanical hybrid braking control is how to coordinate the rela-tionship among front, rear brake force and motor regenerative braking, to ensure the safety of braking distance, the stability of brak-ing direction as well as the efficiency of braking energy recovery. The control of electro-mechanical hybrid braking based on fuzzylogic is proposed in this paper, and embed the reestablished braking dynamics simulation model into the platform of ADVISOR.The results indicate that the distribution between front and rear brake force following the designed curve which meets the safety re-quirements, the ratio of braking energy recovery can reach 43.49% in the condition of CYC_UDDS driving cycle, increase by67.8% compared to the original strategy. They verify the feasibility and effectiveness of this control strategy.
