Embodiment Construction
[0020] The following is further described in detail through specific implementation methods:
[0021] A traffic accident analysis method based on dynamic analysis of driving simulator, such as figure 1 , figure 2 shown, including the following steps:
[0022] (1) Construction of virtual scene and vehicle dynamics model: collect data at the scene of traffic accidents and build a virtual scene. Specifically, when building a virtual scene, three-dimensional road surface scanning and scene scanning are performed, and the scanned data are processed to complete the virtual scene construction of the scene road surface. Scene scanning includes scanning records of the weather conditions at that time, the operation of red street lights, and the driving conditions of surrounding vehicles.
[0023] According to the information of the vehicle involved in the accident, build the vehicle dynamics model, including building the suspension and steering model, building the power system model...

The invention belongs to the technical field of road traffic accident analysis, and particularly relates to a traffic accident analysis method based on kinetic analysis of a driving simulator, which comprises the following steps: (1) building a virtual scene and an automobile dynamic model: collecting data of a traffic accident scene, and building the virtual scene; building an automobile kineticmodel; loading the built virtual scene and the built automobile dynamic model to a driving simulator; (2) virtual driving: carrying out virtual driving on the driving simulator, and if the automobilestate in the virtual scene is consistent with the actual traffic accident, carrying out the next step; if not, repeating the step; and (3) virtual analysis of the traffic accident: extracting the motion state information of the automobile in the virtual traffic accident, and analyzing the cause of the traffic accident. According to the scheme, a real driver participates in the traffic accident through the driving simulator, so that the driver reproduces the response of the driver in the accident process, the response of the driver is also considered, and the analysis accuracy is greatly improved.
Description
technical field [0001] The invention belongs to the technical field of road traffic accident analysis, and in particular relates to a traffic accident analysis method based on dynamic analysis of a driving simulator. Background technique [0002] With the rapid development of my country's road traffic, the incidence of traffic accidents is on the rise, and the severity of accidents is increasing year by year. The safety situation is still severe, seriously affecting the safety of people's lives and property, and seriously affecting economic development and social stability. Therefore, it is very meaningful to analyze traffic accidents, analyze the mechanism of traffic accidents, and propose corresponding safety improvement measures to improve traffic safety conditions from the source. [0003] Foreign studies on the cause analysis of traffic accidents include: P. Kuzminski et al. modeled the causal structure of automobile accidents, and analyzed the possible routes of accide...
