【摘要】：机械式自动变速器(AMT)取消了离合器踏板,离合器的接合与分离由电子控制单元(ECU)驱动电机带动涡轮蜗杆自动完成。AMT叉车起步控制研究的关键问题是保证叉车平稳起步的同时将滑磨功降到最低。离合器的接合是非线性、动态的过程,受驾驶员意图、坡道等许多因素的影响,难以用数学模型来描述。因此采用模糊控制策略对叉车离合器起步过程进行研究,通过建立模糊控制器输出离合器的接合速度和半接合点,并通过图形用户界面(GUI)进行仿真分析。仿真结果表明所制定模糊控制策略能保证叉车起步的良好品质,起步时叉车离合器对内外部条件的变化具有高度的灵敏性。
[Abstract]:The mechanical automatic transmission (AMT) cancels the clutch pedal, The coupling and separation of the clutch is accomplished automatically by the (ECU) motor driven by the electronic control unit. The key problem in the study of the starting control of the AMT forklift is to ensure the smooth start of the forklift and to reduce the sliding grinding power to the minimum. Clutch engagement is a nonlinear and dynamic process, which is influenced by many factors, such as driver's intention, ramp and so on, so it is difficult to be described by mathematical model. Therefore, the starting process of forklift clutch is studied by using fuzzy control strategy. The joint speed and half joint point of fuzzy controller output clutch are established, and the simulation analysis is carried out by graphical user interface (GUI). The simulation results show that the fuzzy control strategy can guarantee the good quality of the forklift truck starting, and the clutch of the forklift truck has a high sensitivity to the change of the internal and external conditions.
