Abstract

To heighten electric vehicle(EV)recovery energy

a brake-force distribution strategy based on motor brake torque is proposed from the viewpoint of maximum energy recovery

together with the analysis of the vehicle brake dynamics and related regulations. Motor model and EV power-train model are established

and simulation is carried out with MATLAB/Simulink. The results show that with the adoption of the strategy

the EV meets braking stability and regulations requirement. Compared with the ideal front and rear braking force distribution

the proposed strategy enables to take advantage of motor brake torque

and simulation results show that it can enhance motor regenerative energy by 56.1% for the Japanese 1015 driving cycle. A remarkable motor regenerative energy improvement can be found for the other driving cycles.
