The invention relates to a power-assisted bicycle pedaling frequency sensor anomaly detection method and device and a power-assisted bicycle. The power-assisted bicycle pedaling frequency sensor anomaly detection method comprises the following steps that a center shaft torque value, a center shaft rotating speed m and a rear wheel rotating speed n are obtained; if the center shaft torque value is not smaller than the preset torque value and the center shaft rotating speed m is not equal to k * n, the pedaling frequency sensor breaks down, and k is the transmission ratio of front and rear wheels. Whether the pedaling frequency sensor is abnormal or not can be detected to a certain degree, and therefore the safety of the power-assisted bicycle is improved.

    本发明涉及一种助力自行车踏频传感器异常检测方法、装置及助力自行车。该助力自行车踏频传感器异常检测方法包括下述步骤:获取中轴力矩值、中轴转速m和后轮转速n;若中轴力矩值不小于预设力矩值,且中轴转速m不等于k*n,则踏频传感器出现故障,其中k为前后轮传动比。本发明能在一定程度上检测踏频传感器是否出现异常,从而提高助力自行车的安全性。
