    • The invention relates to a method for determining the application point of an automatically controlled friction clutch for a motor vehicle automatic gearbox. The inventive method consists in automatically separating the clutch after pre-selecting a new speed, in disengaging the inserted speed, in bringing the engine speed up to a target value for a new speed and in advancing the clutch at a higher advance speed to the application point in which the gearbox input shaft is correctly entrained. In order to determine the application point, the time progression gradient of the input shaft rotational speed is controlled, an important modification of said gradient, which is set when the application point is attained, is detected and the clutch position at that time is defined as application point. The application point determination is preferably carried out during switching back, wherein the speed of rotation of the gearbox input shaft between speed decreasing and a new minimum exhibiting acceleration is easily and accurately determinable.
    • 本发明涉及一种用于确定机动车辆自动变速箱的自动控制的摩擦离合器的应用点的方法。 本发明的方法包括:在预先选择新速度之后,在分离插入速度时,使发动机速度达到新速度的目标值,并以更高的提前速度将离合器推进到应用中,自动分离离合器 齿轮箱输入轴正确夹带的位置。 为了确定应用点,控制输入轴转速的时间递增梯度,检测到在施加点达到时设定的所述梯度的重要修改,并且此时的离合器位置被定义为 应用点。 应用点的确定优选在切换时进行,其中齿轮箱输入轴在速度下降之间的旋转速度与显示加速度的新的最小值之间的转速容易且准确地确定。
