| 摘 要： | 具有固定传动比的机械自动变速器(Automatic manual transmission,AMT)车辆,在换挡过程中,传动比会发生改变,造成离合器主、从动盘产生转速差,会使车辆在换挡过程中不可避免地出现换挡冲击.装备AMT的启动/发电一体化电机(Integrated startergenerator,ISG)型轻度混合动力系统,在换挡过程中,可利用ISG电动机的辅助动力作用,快速控制动力源,提高换档品质.在传统AMT车辆换挡过程分析的基础上,结合轻度混合动力车辆的特点,建立了动力源控制模型,提出了ISG电动机、发动机和离合器联合控制的换挡品质控制策略,在换挡过程中控制动力源转矩和转速,减小了轻度混合动力AMT车辆换挡冲击和动力中断时间.台架试验结果表明,装备AMT的轻度混合动力系统采用所提出的控制策略较传统控制策略能更有效地提高换挡品质.

| Abstract: | Transmission ratio will change as a step after shifting for an automatic manual transmission (AMT) vehicle. Input speed and output speed of clutch are different due to ratio change and jerk occurs. By using the auxiliary dynamic action of ISG motor, the power source can be quickly controlled in shifting process, and shift performance can be improved for mild hybrid electric vehicle equipped with AMT. On the basis of analysis of shifting process on traditional AMT vehicles, and by combining the features of m... |
