Regenerative Braking System for a Pure Electric Bus

Abstract

A design of regenerative braking system (RBS) for a pure electric bus was presented in this paper. A design of regenerative braking system for a pure electric bus was presented in this paper The control of regenerative braking was achieved by Pneumatic ABS and improve braking energy recovery under the premise of ensure braking performance. Regenerative braking control algorithm was mainly composed of two parts for the identification of the drivers intention and the brake force distribution. The regenerative brake control model was built in the matlab/simulink environment, rapid prototyping control was achieved by Autobox and vehicle test was carried on. Result shows that the control strategies can effectively make the pneumatic brake system and motor brake system work harmoniously.
