Study on control strategy for regenerative braking in a pure electric vehicle

Abstract

Regenerative braking is one of the important ways to extend the driving mileage of pure electric vehicle. Through analyzing the brake regulations and the vehicle dynamics, a control strategy was proposed to solve the problem on braking force distribution for the pure electric vehicle. The rate of regenerative braking [1], the rate of energy-saving and the rate of extended driving mileage were served as evaluating indexes of the control strategy. Finally the simulation was carried out by MATLAB/simulink and AVL-Cruise under different profiles. The control strategy was also validated by vehicle experiment. The results show that the strategy can distribute the brake forces rightly and recover relatively more energy. © the authors.
