  • Patent number: 10699496
    Abstract: The present disclosure provides a method for processing data on Internet of Vehicles, a server, and a terminal. In a technical solution of the present disclosure, the server first acquires the historical travel data, and then performs training on the historical travel data to obtain the program script used to analyze the driving behavior of the user, and finally sends the program script to the terminal. The driving behavior of the user is dynamically analyzed according to the program script and the travel data, which resolves a problem that algorithm accuracy decreases because an algorithm is not updated in time, ensures accuracy of analyzing the driving behavior of the user, and further decreases additional costs brought by updating terminal firmware.
