摘要
分析制动强度、IsG电动机制动力、发动机制动力以及电池充电功率的相互关系,得到电动机实际制动力随期望制动强度和车速变化曲面。提出基于电动机实际制动力的前后轮制动力分配策略。在此基础上考虑变速器挡位对传动系统工作点的影响,提出制动过程中能量最大化回收的换挡控制策略。台架试验结果表明,采用所提出的再生制动控制策略比传统控制策略能更有效地回收制动能量。
Actual regenerative braking force of integer starter/ generator (ISG), which is varied with desired braking deceleration and vehicle, is calculated based on analyzing required braking deceleration, maximum braking force of ISG, engine braking force and state of charge (SOC). Braking force distribution strategies are presented according to actual regenerative braking force of ISG. In order to recover vehicle kinetic energy maximally braking shift rules for mild HEV equipped with automatic manual transmission (AMT) are brought forward considering effects of transmission ratios. Test bed is built up and testing results show that power recovered with braking shift rules is more than that recovered with normal braking control rules.
