Regenerative braking for electric vehicle based on fuzzy logic control strategy

In order to recycle more energy in the process of regenerative braking, we design a regenerative braking force calculation controller based on fuzzy logic. The sugeno´s interface fuzzy logic controller has three-inputs including the driver´s brake requirements, vehicle speed and batteries´ SOC and one-output which is the regenerative braking force. To ensure charging safety, the influence of batteries´ temperature is also taken into consideration. Besides, we modify the original braking force distribution regulations in the simulation software-ADVISOR. The simulation results verify that the method can not only recycle more energy from braking but also ensure the safety of braking and the batteries.
