    • The invention relates to a method for carrying out shifting operations for the automatic transmission of a motor vehicle, in particular overlapping shifting operations, for which a first shifting element opens and a second shifting element closes during a shifting operation. To increase the spontaneity and to reduce the shifting frequency, a downshift from a first ratio stage (i1) to a second ratio stage (i2) is interrupted immediately and returned to the first ratio stage (i2), if an interruption criterion is recognised. The interruption criterion is set if a stipulated request by a driver of the motor vehicle for an upshift is recognised before a current transmission input speed (n_T) deviates from a synchronous speed of the first ratio stage (i1), or before a time phase that commenced with said deviation from the synchronous speed of the first ratio stage (i1) has exceeded a predefinable time-based threshold value, or before the current transmission input speed (n_T) has deviated from a synchronous speed of the first ratio stage (i1) by a predefinable, speed-based threshold value, or before a pressure (p_K1) of the deactivating first shifting element falls below a predefined, pressure-based threshold value.
    • 本发明涉及一种用于执行电路的机动车自动变速装置,特别是重叠的电路,其中一个电路在打开和关闭的第一开关元件的第二开关元件的方法。 为了增加自发性和减少从第一传输阶段(I1)的降档,提出了开关频率在第二传输阶段(3-12)并进入第一传输阶段(3-12)瞬时停止时中止标准被识别被返回。 在这种情况下,如果预先确定通过所述机动车辆的请求的升档的驾驶员是当前的变速器输入速度(N_T)离开或之前的第一传动比(I1)的同步速度之前识别(与离开第一齿轮的同步速度的终止标准被设定 计时器开始I1)已经超过一个预定的与时间相关的限制值或当前变速器输入速度(N_T)之前已经通过所述第一传动比(i1的同步速度的预定速度相关的限制值移开)或脱开的压力(P_K1)之前第一切换元件的预定压力有关的限值 跌破。
