A vehicle-road cooperation precise positioning method based on an electrified highway includes measuring position information of its own positioning point by using a roadside positioning module; determining absolute coordinates of all points on a communication line according to the position information; acquiring a contact signal when a vehicle-road connection information system comes into contact with the communication line, and determining position information of a contact point according to the contact signal and the absolute coordinates; and based on a conversion algorithm, determining current vehicle mass center position coordinate information according to the position information of the contact point and parameter information of the vehicle-road connection information system. In the process of real-time acquisition of vehicle dynamic position information, the method does not rely on a satellite positioning system at all and is based on a wired vehicle-road connection of the electrified highway, so that timeliness and reliability are higher.
