The invention relates to an automatic speed changing method, an automatic speed changing system and a bicycle. The automatic speed changing method comprises the steps of obtaining a plurality of acceleration data; generating an acceleration curve graph based on the acceleration data; road conditions are classified according to the relation among the vertical acceleration curve, the left-right acceleration curve, the front-back acceleration curve, the first judgment base line and the second judgment base line; and generating a speed change instruction according to the road condition. The method has the advantages that by acquiring the acceleration data and classifying the road conditions based on the acceleration data, the speed change instructions suitable for different road conditions can be automatically generated, and a rider does not need to change the speed according to experience, so that the speed change efficiency is improved, and the riding efficiency is improved.
本发明涉及一种自动变速方法、自动变速系统及自行车,自动变速方法包括获取若干加速度数据;基于若干加速度数据,生成加速度曲线图;根据垂直向加速度曲线、左右向加速度曲线、前后向加速度曲线、第一判断基线、第二判断基线的关系,对路况进行分类;根据路况,生成变速指令。其优点在于,通过获取加速度数据,并基于加速度数据对路况进行分类,可以自动生成适应于不同路况的变速指令,无须骑车人根据经验变速,以提高变速效率、提高骑行效率。
