配有至少一个形锁合切换元件和多个摩擦切换元件的车辆动力总成系统的变速器装置的操作方法
摘要：
在要求变速比更换的情况下，由于所要求的变速比更换而须打开的形锁合切换元件（F或A）在经过一个预定的额定打开时间之后在一个预定的额定打开时间点时应处于其打开的工作状态中。在执行变速比更换的过程中，根据变速器装置（1）的工作状态参量从形锁合切换元件（A或F）朝向其打开的工作状态的操作的开始点出发确定一个实际打开时间点。在实际打开时间点和额定打开时间点之间存在偏差的情况下，将额定打开时间以一个时间值加以改变并且将形锁合切换元件（A或F）的操作的所述开始点以该时间值相对于额定打开时间点推移和/或将待接通的切换元件（B或C）的操作适配于待断开的形锁合切换元件（A或F）的已确定的工作状态曲线，使得形锁合切换元件（A或F）至少接近在额定打开时间点转入打开的工作状态。
摘要（英）：

When a request is made to change gears, the form-fitting shifting element (F or A) that is to be disengaged as a result of the requested gear change is to be in the disengaged operating state at a predefined desired moment of disengagement following a predefined desired disengagement period. When the gear is actually changed, an actual moment of disengagement is determined based on the moment the form-fitting shifting element (A or F) begins to be actuated in the direction of its disengaged operating state and in accordance with an operating state variable of the transmission device (1). If the actual moment of disengagement deviates from the desired moment of disengagement, the desired disengagement period is modified by a time value, and the moment when the form-fitting shifting element (A or F) begins to be actuated is shifted by said time value in relation to the desired moment of disengagement, and/or an actuation of the shifting element (B or C) to be connected is adjusted to a determined progress of the operating state of the form-fitting shifting element (A or F) to be disconnected such that the form-fitting shifting element (A or F) reaches the disengaged operating state at least approximately at the desired moment of disengagement.
