Put forward a constant torque fuzzy control strategy to solve the problem of low efficiency in electric vehicles energy feedback braking. At first, made the analysis of the basic principles of energy regenerative braking of BLDCM. At the same time, a threedimensional fuzzy controller through the comparative analysis of the different feedback control strategy was designed, and a BLDCM regenerative braking system simulation model in the MATLAB/Simulink environment was established. Results showed that the control strategy reached good control effects to motor braking torque and energy recuperation.
