摘要
研究电动汽车电机制动+EHB复合制动系统性能优化问题,提出理想制动力分配控制策略。分析制动时各环节的约束条件:制动法规的约束、电机特性的约束、制动稳定性的约束以及制动舒适性的约束条件,然后运用ISIGHT软件进行优化设计。再运用SIMLINK软件建立动力学和控制模型,选取上海典型城市公交循环工况,进行仿真。与并行制动控制策略比较,优化后的理想制动力分配策略不仅很大程度上提高制动能量回收效率,而且大大提高制动效能和制动平顺性。
Based on the design of electric car with electric ＋ EHB braking system, the design put forward the control strategy of ideal braking force distribution. The constraint conditions of braking were analysed as ： the constraint of braking regulations, the constraint of motor characteristics, braking stability and braking comfortable. And the opti- mum design was made by ISIGHT software. The dynamics and control models were established by SIMLINK software, then the Shanghai typical city bus driving cycle was selected. Compared with the parallel braking control strategy, the ideal braking force distribution strategy can not only greatly enhance the braking energy recovery efficiency, but also greatly improve braking efficiency and comfort.
