Problems solved by technology

In these studies, the characterization method of driving behavior safety is relatively simple, the characterization indicators are not comprehensive and systematic, and the analysis of the driver's environmental perception data is lacking.
In addition, most of the research data are obtained through driving simulators, and there are few analysis and evaluation of the safety of driving behavior using the data obtained when the vehicle is driving in the real road environment, which cannot truly reflect the normal driving behavior in the actual driving environment.

Abstract

The invention relates to the field of automobile driving safety, and discloses a method for constructing a driving behavior safety evaluation model based on a real automobile test, and the method comprises the implementation steps: collecting eye movement information, automobile operation information, radar information and lane line information of a driver during the driving process of an automobile on a test road section; calculating a numerical value of each driving behavior safety evaluation index characterization quantity; and taking the calculated characterization quantity value as an index, calculating the weight of the characterization quantity value, and finally obtaining a driving behavior safety evaluation model. According to the method, numerical evaluation is carried out on the driving behavior safety of the driver by utilizing the real vehicle test data, the evaluation result has the advantages of visualization and comparability, and the driving behavior safety of the driver in the conventional driving process can be reflected better. Meanwhile, common dangerous driving behaviors of the driver in the driving process can be known according to the numerical value of the characterization quantity of each evaluation index, and the method is of great significance in improving the driving habit of the driver and reducing traffic accidents and traffic violation.

Description

technical field [0001] The invention relates to the field of automobile driving safety, in particular to a method for constructing a driving behavior safety evaluation model based on real vehicle tests. Background technique [0002] In recent years, with the popularity of vehicles, traffic safety problems have become increasingly serious. According to statistics, the number of deaths caused by traffic accidents in the world exceeds 1.2 million every year. Relevant studies have shown that dangerous driving behavior is one of the most important causes of traffic accidents. Among the causes of traffic accidents promulgated by domestic and foreign transportation departments, the traffic accidents caused by drivers account for more than 70%, and the driving behavior of drivers has a significant impact on the safety and reliability of urban traffic systems. Therefore, it is very necessary to conduct research on the construction of a driving behavior safety evaluation model, whic...
