摘　　要：以5速干式DCT为研究对象,分析干式DCT车辆起步过程,搭建车辆起步过程动力学及控制策略模型,同时基于未知输入重构并运用高阶滑模观测器对起步过程离合器传递转矩进行仿真估计。仿真结果表明,采用高阶滑模观测器以及未知输入重构能较好估计出DCT车辆起步过程离合器实际传递的转矩。By studying the five-speed dry DCT and analyzing the starting process of vehicle equipped with dry type DCT, we establish the dynamics ＆ control strategy of the vehicle during the starting process. Meanwhile the clutch torque transmitted during the starting process is estimated utilizing the high order sliding mode observer based on unknown input reconstruction. The simulation results show that the sliding mode observer and the unknown input reconstruction can estimate the clutch torque effectively for vehicle equipped with DCT in the starting process.
