Energy regenerative braking ABS control research on feedback lockup driving-braking integrated system for electric vehicles

Abstract

Project the braking feedback lockup braking-driving integrated system for electric vehicles. Design and optimize the integrated system based on the motor and the disc brake. Set up the integrated system dynamic model. Based on the Matlab/Simulink, establish the simulation system of regenerative braking dynamic and ABS control for the electric vehicles with the braking-driving integrated system. Based on the simulation system, respectively simulate and analyse the regenerative braking performances with or without ABS control on three conditions: driving straightly on high adhesion condition ground, low adhesion condition ground and steering driving on a curve path. The study results indicate that the electric vehicle with the braking-driving integrated system has better ABS performances than the electric vehicle with the general brake system, and has more the regenerative braking efficiency than other regenerative braking systems.
