中文摘要：

离合器控制的优劣是影响机械式自动变速车辆起步和换挡平顺性的最重要因素,传统PID控制方法难以对电控机械式自动变速器（AMT）离合器这种复杂的大滞后、非线性系统进行精确控制。对灰色预测PID控制在AMT离合器控制中的应用进行了深入研究,与传统控制方法相比,该方法提高了离合器的控制精度。灰色预测PID控制使控制系统的灰量得到一定程度的白化,提高了控制的质量和鲁棒性,有效解决了离合器控制的超调和震荡问题,提高了车辆起步与换挡的平顺性。

英文摘要：

The underway and shift smoothly of automated mechanical transmission（AMT） vehicle are influenced by the clutch control property,it is difficult to be precisely handled by traditional PID control technology.The main reasons are the big hysteresis and nonlinear characteristics of clutch and actuation system.The gray prediction PID control technology in clutch control of AMT was analyzed.The control precision of clutch was improved by the proposed technology compared with traditional PID control technology.The gray prediction PID control could whiten certainly gray factors in the control system,improve the control quality and rubust of PID,and solve the problems of overrun and oscillation of clutch control.Thus,the underway and shift smoothly for vehicle were improved.
