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.

A temperature monitoring method of a brake of a freight vehicle based on TBOX is provided, including: determining a weight of the freight vehicle based on OBD data of the freight vehicle collected by the TBOX; inputting the weight, the OBD data, a longitudinal slope in a high-precision map to determine the temperature of the brake of the freight vehicle; setting a temperature warning threshold of the brake based on its performance parameters of the freight vehicle, and determining a first driving state and a second driving state in a front road section with the determined temperature of the brake, and generating a warning signal and a forewarning signal of the freight vehicle. The monitoring method improves accuracy of the brake temperature by introducing altitude variation of the front road section and weight of the freight vehicle, and provides powerful data support for a safe driving.
