Abstract: A method of controlling a transmission includes detecting a first inflection point and a second inflection point in the movement of the accelerator pedal. An amplitude between the first inflection point and the second inflection point is then calculated, and a period of time between the first inflection point and the second inflection point is measured. An attenuation coefficient is defined from the amplitude and the measured period of time between the first and second inflection points. A current iteration temporary gear ratio is defined as the gear ratio calculated during the most recent iteration of an iterative gear ratio selection algorithm, and is adjusted with the defined attenuation coefficient to define a current iteration final output gear ratio. The operation of the transmission is then controlled to change the transmission from a previous iteration final output gear ratio to the current iteration final output gear ratio.

Abstract translation: 控制变速器的方法包括检测加速踏板运动中的第一拐点和第二拐点。 然后计算第一拐点和第二拐点之间的幅度，并且测量第一拐点和第二拐点之间的时间段。 衰减系数由第一和第二拐点之间的振幅和测量的时间段定义。 当前迭代临时齿轮比被定义为在迭代齿轮比选择算法的最近迭代期间计算的齿轮比，并且利用所定义的衰减系数来调整以定义当前迭代最终输出齿轮比。 然后控制变速器的操作，以将传动从先前的迭代最终输出齿轮比改变为当前的迭代最终输出齿轮比。
