The Control Strategy of Regenerative Braking of Four-Wheel-Drive Electric Vehicle
Electric vehicles with four in-wheel motors have its inherent advantage to recover energy because all of its four in-wheel motors can generate electricity energy when braking. For the purpose of study the property of regenerative braking of four-wheel-drive electric vehicles, three traditional distribution strategies of traditional vehicles are adjusted based on the property of in-wheel-motor. A simulation model is established by using Matlab/Simulink and CarSim software, and the simulation is made based on UDDS and 1015 driving cycles. The simulation result shows that, the parallel distribution strategy has the highest regenerative efficiency and regenerative efficiencies of fixed proportion distribution strategy and ideal distribution strategy are almost the same.
