A gear stage estimation method for estimating a gear stage of a switching transmission device (30) of an electric bicycle (10), the electric bicycle (10) comprising: a motor (M); and a switching transmission device (30) that is provided on a power transmission path between the motor (M) and the rear wheel (78) and that can switch n gear stages. The shift range estimation method includes: acquiring, at a first time, a detection gear ratio (Rd), which is a gear ratio of a transmission section that is the whole or part of a power transmission path including a switching transmission device (30); and a step for comparing n preset gear ratios (Ri) set within the range of gear ratios that can be taken by the n gear stages with the acquired detected gear ratio (Rd), and estimating the gear stage of the shift transmission device (30) as the m gear stage when the detected gear ratio (Rd) matches the m-th preset gear ratio (Ri).

    变速挡推定方法用于推定电动助力自行车(10)的切换变速装置(30)的变速挡,电动助力自行车(10)具有:马达(M);以及切换变速装置(30),其设置在马达(M)与后轮(78)的动力传递路径上,能够切换n个变速挡。变速挡推定方法包含如下步骤:在第一时间,取得包含切换变速装置(30)在内的作为动力传递路径的整体或一部分的传递区间的变速比即检测变速比(Rd);以及将设定在n个变速挡可取的变速比的范围内的n个预设变速比(Ri)与所取得的检测变速比(Rd)进行比较,在检测变速比(Rd)与第m号预设变速比(Ri)一致的情况下,将切换变速装置(30)的变速挡推定为m挡。
