Abstract	A new fault-tolerant control method for Hall sensors in brushless DC motor driver of E-bicycle is presented. Contrary to the classical fault-tolerant control method that focused their attention on fault diagnosis, the proposed method uses pulse-width modulation input capture function to extract sensors' effective information and eliminate fault information, which helps to omit the process of fault diagnosis and improve the efficiency of fault-tolerant control. The effective information of Hall sensors includes edge jump information and velocity information, which are used to correct and estimate the rotor angle under field oriented control. The effectiveness and rapidity of the proposed fault-tolerant approach are illustrated through experimental results.
