Abstract Aimed at the problem that the robustness of clutch engaging control of AMT for starting is poor due to the attrition of clutch， the change of working temperature， the change of vehicle load， the change of traffic conditions and so on， we proposed a method of engaging control of AMT clutch for starting based on speed feedback， made speed as the target of clutch engaging control. According to the input of accelerator pedal， the AMT controller generated the target speed of starting process， detected the change of the speed in realtime， adjusted the engaging speed and engagement dynamically with fuzzy control method according to the error of real speed and target speed， to make real speed track the target speed and change gently. It improves the robustness of clutch engaging control of AMT for starting.

基于车速反馈的AMT离合器起步接合控制
针对AMT系统离合器起步接合控制由于离合器磨损、工作温度变化、车辆载荷变化以及路况条件变化等造成的鲁棒性差问题，提出了基于车速反馈的AMT离合器起步接合控制方法，以车速作为离合器起步接合控制的目标.根据加速踏板的输入产生起步过程中的目标车速，实时检测车速的变化，采用模糊控制方法，根据实际车速与目标车速的偏差，动态调整离合器的接合速度和接合量，使实际车速跟踪目标车速平稳变化，提高了AMT离合器起步接合控制的鲁棒性.
