Data measurement and providing method for an electric assist bicycle

Abstract

The present invention provides a data measurement and providing method for an electric assist bicycle, which accurately measures and records voltage, current and power data through a voltage sensor, a current sensor and a power sensor. These data are collected by a sensor module, and processed and analyzed by a capturer to calculate the real-time power value and assistance ratio. These data can not only reflect the operating status of the electric assist system, but can also be used to dynamically adjust the assistance mode to achieve the best riding performance. Power calculation can help monitor the load conditions of the motor and battery to ensure that the most suitable power support is provided under different riding conditions. Through real-time analysis and feedback of these data, the present invention achieves the purpose of improving the performance of the electric assist bicycle and improving the comfort of the rider.

Claims
