The electric vehicle braking system and fuzzy control principle of theoretical analysis, through the design of fuzzy controller, in the original ADVISOR2002 feedback braking system model based on the basis of the principle of fuzzy control, a fuzzy control model of braking system, pure electric vehicle braking feedback control module optimization. In the simulation environment of ADVISOR2002, the model is validated by vehicle simulation. In the simulation of several typical cycle conditions through the simulation software to verify the feasibility of the model, and show the superiority of the fuzzy control model, effectively improve the energy recovery efficiency of pure electric vehicles, extending vehicle mileage, embodies the practicality and economy of fuzzy control model.
