    • A method is provided for operating an automatic transmission for a vehicle, that includes, but is not limited to detecting whether a target speed of the vehicle is set, calculating an optimum acceleration gear in dependence of an actual virtual accelerator pedal position, and, if the optimum acceleration gear differs from a current gear, storing the actual virtual accelerator pedal position, shifting to the optimum acceleration gear and ignoring newly calculated actual virtual accelerator pedal positions for an acceleration period of time. Since the actual virtual accelerator pedal position is stored in the case of a detected necessary gear shift and further calculated actual virtual accelerator pedal positions are ignored for a time, the operating of the transmission is based mainly on the value of the actual virtual accelerator pedal position at the time, when a necessary gear shift is detected. The risk that due to insignificant changes of the accelerator pedal position the gear is shifted up and down several times (“gear hunting”) until the target speed is reached is reduced.
    • 提供一种用于操作车辆的自动变速器的方法,其包括但不限于检测车辆的目标速度是否被设定,根据实际的虚拟加速器踏板位置计算最佳加速档,并且如果 最佳加速档与当前档位不同,存储实际的虚拟加速器踏板位置,移动到最佳加速档,并忽略新计算的实际虚拟加速踏板位置加速时间段。 由于在检测到必要的换档的情况下存储实际的虚拟加速器踏板位置,并且进一步计算出的实际虚拟加速器踏板位置一段时间被忽略,所以变速器的操作主要基于实际虚拟加速器踏板位置的值 当时检测到必要的换挡。 由于加速踏板位置的微小变化导致齿轮上下移动几次(“齿轮摆动”)直到达到目标速度的风险降低。
