Driving behavior safety evaluation method based on human-vehicle-environment multiple data sources

Abstract

The invention provides a driving behavior safety evaluation method based on human-vehicle-environment multiple data sources and belongs to the field of automobile safety driving research in the aspectof road transportation application. The method comprises the steps that information data of a driver, driving data of a vehicle and environmental factor data are acquired as automobile driving sourcedata; according to the automobile driving source data, related factors which influence the driving safety are analyzed, and a driving risk evaluation index system is built; through statistical analysis, an evaluation value corresponding to an evaluation index is extracted in the source data, a driving risk score of a vehicle to be evaluated is calculated and obtained, and finally the driving behavior safety grade of the vehicle is determined. The driving behavior safety evaluation method has reliable evaluation results, can prevent dangerous driving behaviors, reduces traffic accidents and improves the traffic flow.

Description

technical field [0001] The invention belongs to the field of automobile safety driving research in road transportation application, and in particular relates to a driving behavior safety evaluation method based on human-vehicle-environment multiple data sources. Background technique [0002] In the process of driving a car, there are many subjective and objective unsafe factors. For example, when driving forward, the driver performs operations such as sudden braking and overtaking, which lead to safe driving accidents. Another example is that due to overtime driving or physical discomfort, the driver cannot perform his driving skills normally, and the operation stagnation or operation error occurs, resulting in a safe driving accident. In addition, if the condition of the vehicle itself or the environment is not good, such as rain and snow, it will also affect safe driving. [0003] With the gradual deepening of the application of the Internet of Vehicles, the installation...

Problems solved by technology

[0008] The disadvantage of the above-mentioned first patent is that it only provides a comprehensive evaluation index system for freight transport risks, but does not give specific judgment basis for each index

In addition, the patent "a vehicle safety driving monitoring device" only considers the factors that affect the safe driving of the car from the perspective of the driver, ignoring the impact of the driving state of the car and the environment on the safe driving of the car, so that it cannot comprehensively analyze the driver's driving status. The state in the process, the resulting evaluation results also lack reliable basis
