摘　　要：To reduce shock during transmission gear shift, a transmission torque feedback closed loop control system is proposed based on the powertrain system model and a torque observer. The ignition time of engine was delayed to reduce transmission output shaft torque during gear shift. In contrast to traditional control method, the closed loop control system based on torque observer can obviously reduce the transmission output shaft torque during gear shift. It can be concluded that by way of torque feedback closed loop control, transmission shift shock can be reduced.为了减小换档过程的冲击 ,提出基于动力传动系统模型和扭矩观测器的变速箱扭矩反馈闭环控制系统 ,在换档过程中推迟发动机点火时刻以降低变速箱输出轴扭矩 .与传统控制方法相比 ,基于扭矩观测器的闭环控制系统能够明显降低换档过程中变速箱输出轴扭矩 .实验结果表明 ,通过扭矩反馈闭环控制方法 。
