Abstract

The invention discloses an electric bicycle power-assisted control system and method based on fatigue. The control system comprises a physiology signal acquisition module and a signal processing center module, wherein the signal processing center module is used for calculating the fatigue degree of a rider according to the real-time heart rate, the real-time breathing rate and the unit-time exercise amount of the rider, acquired by the physiology signal acquisition module; an electric motor is used for outputting corresponding assisting power Q according to the fatigue degree, wherein the proportion of the assisting power is T=(Q+R)/P, T is equal to or less than 1, P represents the normal riding speed of the rider not being under a fatigue state, and R represents the riding speed of the rider being under the fatigue state. According to the electric bicycle power-assisted control system and method disclosed by the invention, appropriate electric assisting power can be provided according to the fatigue degree of the rider in the riding process, and relieving the current fatigue condition of the user is facilitated.

Description

technical field [0001] The invention relates to an electric bicycle power assist control system, in particular to a fatigue-based electric bicycle power assist control system and method. Background technique [0002] As a traditional industry, the bicycle industry has a history of more than 100 years. Due to environmental protection and transportation problems, bicycles have once again become a favorite transportation and fitness tool for residents of countries all over the world, especially developed countries. People's living standards continue to improve, and people yearn for health while pursuing income balance. Cycling has also become a sport that people love and pay attention to. Now, more and more people have joined the ranks of bicycle travel, but only relying on users' own good riding skills and improving bicycles cannot meet people's requirements for long-distance bicycle travel. Electric bicycles have emerged as the times require. The basis of the bicycle is comp...
