Zusammenfassung:	A method comprises the following steps: receiving a first shaft speed; measuring PTO shaft speed parameters; determining PTO shaft acceleration speed through monitoring PTO shaft speed parameter changing with time; using multi estimators to determine a plurality of standard PTO clutch transmission ratios, wherein each of the plurality of estimators determines one of a plurality of normalized PTO clutch ratios based at least in part on an option at a first axis speed, a PTO axis speed, and a plurality of known PTO transmission ratio options; selecting one of the estimator when the PTO shaft acceleration speed drops to the threshold, wherein the standard PTO clutch transmission ratio determined by the selected estimator is about 1. 种方法，包括：接收第轴速度；测量表示PTO轴速度的参数；通过监测表示随时间的PTO轴速度的参数来确定PTO轴加速度；经由多个估算器确定多个标准化PTO离合器传动比，其中，多个估算器中的每个至少部分地基于第轴速度、PTO轴速度以及多个已知PTO变速器传动比选项中的个选项来确定多个标准化PTO离合器传动比中的个；以及当PTO轴加速度下降到阈值以下时，选择多个估算器中的个，其中，由所选择的估算器确定的所述标准化PTO离合器传动比为大约1。
