Abstract

The present invention relates to the technical field of automatic driving, and discloses a modeling method, device, equipment and storage medium for triggering events. The method includes: obtaining a preset risk concentration point, and using the preset risk concentration point as a first construction Modeling conditions, divide the automatic driving system according to the preset division strategy, obtain the corresponding layer, use the corresponding layer as the second modeling condition, and compare the first modeling condition and the second modeling Combining and analyzing conditions to obtain trigger events, analyzing and refining the automatic driving system, obtaining corresponding process nodes, analyzing the trigger events according to the corresponding process nodes, obtaining target trigger events, and Model the target triggering events described above. The present invention obtains and models triggering events through combined analysis of preset risk concentration points and layers, and can effectively model triggering events, thereby improving driver safety.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, and in particular to a modeling method, device, equipment and storage medium of a trigger event. Background technique [0002] As the vehicle ADAS (Advanced Driving Assistance System, Advanced Driver Assistance System) driving assistance functions become more and more complex, and the level of autonomous driving is getting higher and higher, many safety problems are not necessarily caused by system failures. Traditional automotive functional safety ISO26262 The coverage is limited, and due to the limitation of the sensor or the misoperation of the driver will also lead to risks, ISO21448 came into being and is getting more and more attention. The definition of scenarios in ISO21448 is divided into: known safe scenarios, unknown safe scenarios, known unsafe scenarios, and unknown unsafe scenarios. The resulting risks are unacceptable. The purpose of expected functional safety i...
