Fuzzy control has great advantages in dealing with imprecision and uncertainty in inference systems and control systems. At present, an important area of the development of new energy vehicle vehicles, the purpose is to save non-renewable resources and reduce air pollution, good control methods can improve the energy efficiency of new energy vehicles. This paper focuses on the recovery and utilization of braking energy in gasoline-electric hybrid vehicles, which increases the energy reuse of gasoline-electric hybrid vehicles, so that the energy consumption of the whole vehicle is lower and the pollution is less. In this paper, fuzzy control theory is used to reasonably allocate the ratio of mechanical braking and regenerative braking according to vehicle speed and braking requirements, so as to achieve a reasonable balance between braking reliability and braking energy recovery when braking.
