Abstract The motor model and the dynamic safety distance model were proposed, and the vehicle dynamics model of pure electric vehicle was built on the Carsim platform. The fuzzy distance controller was designed, and the Simulink and Carsim joint simulation platform was established to conduct the simulation analysis of the pure electric vehicle fuzzy distance controller. The results show that the controlled vehicle can ensure the safe distance more than 5 m from the preceding vehicle compared with the vehicle without controller. When the starting distance of preceding vehicle are 50，80 and 100 m, the minimum distance can be controlled more than 5 m. Under the condition of cutting in the adjacent lanes, the rearend collision and other collisions can be effectively prevented, and the active safety of vehicle and the efficiency of road passage can be greatly improved.
