Embodiment Construction

[0042] The existing driving behavior analysis methods usually collect vehicle data in real time, and analyze the user's driving behavior based on the real-time collected vehicle data. Since the factors affecting the user's driving behavior are different in different scenarios, the obtained driving behavior It cannot reflect the actual driving situation of the user, and the accuracy is low.

[0043] In order to solve the above problems, in the embodiment of the present invention, the trained driving behavior analysis model is adopted, and the number of occurrences of each driving behavior within the preset mileage is used as an input parameter. A corresponding weight in a mapping relationship is used to calculate the collision occurrence probability of the vehicle. Average the number of occurrences of each driving behavior within the first period of time to the preset mileage, thereby reducing the impact of a single driving behavior on the calculated collision probability, ther...

Abstract

A driving behavior analysis method, device and system. The method includes: acquiring the driving behavior data of the vehicle within a preset first time period and the driving mileage of the vehicle within the first time period; processing the driving behavior data within the first time period to obtain the driving behavior data The number of occurrences within the preset mileage; the obtained number of occurrences of each driving behavior within the preset mileage is input to the trained driving behavior analysis model, and the collision occurrence probability of the vehicle is calculated using the driving behavior analysis model and output, wherein, the input parameters of the driving behavior analysis model include driving behavior, there is a first mapping relationship between the driving behavior and the collision occurrence probability of the vehicle, and the driving behavior in the driving behavior analysis model is obtained through training. Behaviors correspond to weights in the first mapping relationship. By adopting the above solution, the accuracy of driving behavior analysis and driving safety can be improved.

Description

technical field [0001] The present invention relates to the technical field of Internet of Vehicles, in particular to a driving behavior analysis method, device and system. Background technique [0002] With the development of society, automobiles have become an indispensable means of transportation for people in daily transportation. Currently, driving behavior analysis of vehicles is used in various scenarios. For example, an insurance company conducts analysis based on the driving behavior of the vehicle, and determines the vehicle insurance premium based on the driving behavior analysis results. Another example is that some companies determine the driver's driving experience according to the driver's driving behavior when recruiting drivers. [0003] However, the accuracy of the driving behavior analysis results obtained by the existing driving behavior analysis methods is low. Contents of the invention [0004] The technical problem solved by the invention is how t...
