A regenerative braking system for electric vehicle with four in-wheel motors based on fuzzy control

In order to save energy and improve the driving distance of electric vehicle, a regenerative braking control strategy based on fuzzy control for the electric vehicle with four in-wheel motors is proposed in this paper. Firstly, the braking force is distributed between front axis and rear axis to ensure the safety and stability of the vehicle. Secondly, the braking force is distributed between hydraulic braking and the motor braking. The required braking force can be obtained from the braking force calculation module, and the proportion of regenerative braking force can be obtained from the fuzzy controller. Finally, the mamdani fuzzy controller is established under the Matlab/Simulink environment and embedded into the vehicle model which established on AMESim software. The effectiveness of the proposed control strategy is verified by the simulation.
