The invention provides an electric bicycle hand brake fault detection method, an electric bicycle and a storage medium, and the method comprises the steps: determining a time node when a real-time brake stroke is equal to a first preset threshold value when the real-time brake stroke changes from small to large, and obtaining the speed of the electric bicycle at the initial time node; brake stroke node values within a first preset duration after the initial time node are collected according to a preset time interval, a first brake stroke data set is obtained, and elements meeting the condition that the difference value between the brake stroke node values and the maximum brake stroke value is smaller than a second preset threshold value serve as a second brake stroke data set; and determining the time interval from the initial time node to the minimum time node, obtaining the speed of the electric bicycle at the minimum time node, and further determining the average acceleration within the duration, thereby determining whether the current hand brake is in a fault state or not. The detection efficiency is high, and whether the brake is in the fault state or not can be truly fed back.

    本发明提供一种电单车手刹故障检测方法、电单车及存储介质,在实时刹车行程在从小到大变化时,确定实时刹车行程等于第一预设阈值时的时间节点,获取初始时间节点的电单车的车速,并按照预设时间间隔采集从初始时间节点开始后第一预设时长内的刹车行程节点值,得到第一刹车行程数据集,将满足刹车行程节点值与刹车行程最大值的差值小于第二预设阈值的元素作为第二刹车行程数据集,以确定从初始时间节点到最小时间节点之间的时间间隔,以及获取最小时间节点的电单车的车速,进而确定在时长内的平均加速度,从而确定当前手刹是否处于故障状态。本申请具有检测效率高、能够真实反馈出刹车是否处于故障状态。
