| 摘 要： | 针对纯电动汽车电液复合再生制动过程机电制动力的动态分配问题,通过对制动动力学和ECE R13-H制动法规的分析,从理论上确定纯电动汽车电液复合再生制动的安全运行范围。在安全制动范围内,开发了以最大限度回收能量为目标,达到需求制动强度而前、后轴又不抱死的再生制动控制流程,生成机电制动力分配矩阵。以制动强度分别为0.2,0.3,0.4,0.5和0.6,初始车速为16.67 m/s,结合ECE-EUDC道路循环,构建新的仿真循环,将车辆参数、制动力分配矩阵、道路循环嵌入ADVISOR2002软件。研究结果表明:仿真运行1个道路循环后,电池荷电状态SOC(State of charge)相对原策略有较明显的提高,提高幅度达4.5%,较好地回收了制动能量,更重要的是保证了制动安全,表明开发的控制策略是有效的。

| Abstract: | The braking force distribution of the compound brake system on small electric vehicles was studied.The safe range of braking force distribution was established by analyzing braking dynamics and the ECE R13-H rule.In the safe braking range,a strategy with optimal energy recovery was developed based on the concept,i.e.braking forces should be distributed on front and rear axles in such a way that the regenerated energy was maximized,as long as the commanded deceleration was reached and neither front nor rear ... |
