Problems solved by technology

[0004] Existing technical deficiencies: ①Generally, the development is not based on traffic accidents or dangerous driving events that occur in the real traffic environment, and it cannot realize the model construction from multi-sample traffic accidents or dangerous driving event characteristics research to typical dangerous driving simulation scenarios; ②Have Most of the driving simulators with the customization function of the vehicle-level dynamic model are car dynamic model simulators, which do not have the simulation function of truck dynamics simulation, let alone realize the simulation of the influence of liquid sloshing in the tank on the motion characteristics of the vehicle during the driving process of the liquid tank truck
[0008] Vehicle dynamics simulation software (such as carsim, trucksim, etc.) can realize vehicle dynamics simulation at the vehicle level, but it can only perform simple road traffic environment modeling, and cannot conduct highly customized driving simulations based on real road traffic environments scene development

Abstract

The invention relates to a driving event simulation reappearing method and system, a device, and a storage medium. The driving event simulation reappearing method comprises the following steps: obtaining a driving event data set and vehicle parameters; preprocessing the acquired driving event data set, and constructing a vehicle dynamics model according to the vehicle parameters; acquiring drivingenvironment information, classifying the driving environment information, and extracting a plurality of driving event feature scenes; constructing a driving simulation virtual environment, and establishing a driving simulation scene based on the extracted driving event feature scene; sending the driving simulation scene and the vehicle dynamics model to a driving simulation system so that the driving simulation system simulates and reproduces the driving environment in the driving process of the vehicle. The driving simulation system acquires the simulated driving behavior data of the targetvehicle, then acquires the motion feedback of the target vehicle based on the driving environment and visually displays the motion feedback, so that the complete representation of the field road traffic environment where the traffic accident occurs is realized, and the development of a highly-customized driving simulation scene is realized.
