Problems solved by technology

[0003] However, relying on mileage to determine driving risk has the disadvantage of inaccurate assessment
For example, when the driving mileage of two drivers is the same, according to the existing risk assessment method, the driving risk of the two drivers should be the same. Relying on mileage can no longer meet the current refined demand for risk assessment

Embodiment Construction

[0052] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0053] Such as figure 1 As shown, a schematic flow chart of a driving risk assessment method provided by an embodiment of the present invention, the method includes:

[0054] S1, collecting driving information of the vehicle.

[0055] It should be noted that the collected driving information refers to the driving time, driving distance, real-time speed information, speed change information, acceleration change information, driving direction change information, etc. of the vehicle during a certain driving process. By collecting these driving information, Helps to comprehensively assess driving risk.

[0056] For the collection of driving information, there are actually many ways to realize it. For example, the vehicl...

Abstract

The invention discloses a driving risk evaluation method and a driving risk evaluation system and relates to the field of traffic risk evaluation. The driving risk evaluation method comprises the following steps: acquiring driving information of a vehicle; processing driving information so as to obtain abnormal driving information of the vehicle; acquiring accident information, and establishing amachine learning model for evaluating driving risks according to the abnormal driving information and the accident information; evaluating the driving risks of the vehicle according to the machine learning model. By adopting the driving risk evaluation method and the driving risk evaluation system disclosed by the invention, driving risk evaluation results with very high precision can be acquired,risks of an evaluated vehicle can be accurately and objectively evaluated, fine requirements on risk evaluation are met, adverse driving behaviors of drivers can be corrected in time, and accident risks can be reduced.

Description

technical field [0001] The invention relates to the field of traffic risk assessment, in particular to a driving risk assessment method and system. Background technique [0002] At present, the evaluation methods for driving risk all use static data as characteristics to evaluate risk, and these characteristics are often only indirectly related to accidents, and the correlation is low. For example, the most important reference index in the current method of evaluating risk by using driving behavior is the driving mileage. The core idea is that the higher the driving mileage of the user, the higher the risk of accident. [0003] However, relying on mileage to determine driving risk has the disadvantage of inaccurate assessment. For example, when the driving mileage of two drivers is the same, according to the existing risk assessment method, the driving risk of the two drivers should be the same. Relying on mileage can no longer meet the current refined demand for risk asse...
