Abstract: Embodiments of the present invention provide a method and an apparatus for determining a vehicle acceleration, which are used to eliminate an interference element in data of an accelerometer, and correct accelerometer data that is obtained after interference is eliminated, into acceleration data of a vehicle. The method includes: acquiring original acceleration data measured by the accelerometer in a running process of the vehicle; eliminating, according to the acquired original acceleration data, interference generated by gravity on the original acceleration data, and interference generated, on the original acceleration data, by a change of an angle of the accelerometer caused by moving of the accelerometer relative to the vehicle; and determining acceleration data of the vehicle in the running process according to original acceleration data that is obtained after interference is eliminated.

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.
