Abstract
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.
