Abstract

The invention discloses a risk degree quantification method for automobile driving potential danger scenes, which comprises the steps of extracting primary, intermediate and final risk factors in a grading manner according to potential risk scene components, then calculating the risk degree membership degree of the final risk factors, calculating the weight values of the primary risk factors and the intermediate risk factors, calculating a risk degree membership degree of the primary risk factor; and finally, calculating the risk degree of the potential dangerous scene of automobile driving according to the weight value and risk degree membership degree of the primary risk element, the driving speed and the potential dangerous movement speed. Risk scenes can be measured by using quantitative indexes, and the invention has the advantages of quantifiability, simple method and high quantization precision.

Description

technical field [0001] The invention belongs to the technical field of driver safety risk management, and in particular relates to a method for quantifying the risk of potentially dangerous situations in automobile driving. Background technique [0002] The driver's risk identification is a special risk management behavior, which is a driving behavior in which the driver identifies and evaluates the risk level of the traffic environment, and adjusts the driving state of the vehicle accordingly to ensure safe driving. It is closely related to road traffic safety. At present, scholars at home and abroad have studied a variety of methods to evaluate the driver's risk identification ability, but the accuracy and validity of the evaluation results obtained by these evaluation methods have been questioned. The risk degree of potentially dangerous situations of car driving is one of the important factors affecting the reliability and validity of the evaluation results. Since diffe...
