Embodiment 1

[0050] The embodiment of the present invention provides a driver risk perception ability evaluation system based on virtual reality, such as figure 1 shown, including:

[0051] The VR driving simulator 1 and the management platform 2 use a network connection to realize real-time communication between the VR driving simulator 1 and the management platform 2 .

[0052] The VR driving simulator 1 is used as an evaluation platform for the driver to log in, collect the driving manipulation information and gaze position information of the driver during simulated driving, run the VR road traffic risk driving scene, display the evaluation results of the risk perception ability, etc.;

[0053] The management platform 2 includes a VR road traffic risk driving scene library and an evaluation database, which are used to manage the VR road traffic risk driving scenes and evaluation data, calculate the risk perception ability evaluation results, etc.; the VR road traffic risk driving scene ...

Embodiment 2

[0056] The embodiment of the present invention provides a method for evaluating the driver's risk perception ability based on virtual reality, such as figure 2 shown, including:

[0057] Step S1: When the driver starts the assessment, the VR driving simulator selects k (k>1) driving scenes for assessment from the VR road traffic risk driving scene library according to preset selection rules to form a combination of assessment driving scenes.

[0058] In the embodiment of the present invention, the preset selection rule is determined according to the actual driving ability requirement to be tested, so that a corresponding driving scene is selected to form a combination of driving scenes for evaluation.

[0059] Step S2: When the driver simulates driving in the cockpit, the management platform receives and stores the driver's driving manipulation information and gaze position information and VR road traffic risk driving scene information sent by the VR driving simulator in real...

Abstract

The invention discloses a driver risk perception ability evaluation system and method based on virtual reality, the system is constructed by adopting a VR driving simulator and a management platform, the management platform comprises a VR road traffic risk driving scene library and an evaluation database, and the system has the advantages of strong immersion, small interference and the like. When evaluation is started, the VR driving simulator selects a plurality of driving scenes from the driving scene library to form an evaluated driving scene combination, and the management platform receives and stores driver driving manipulation and watching position and driving scene information sent by the VR driving simulator in real time. Calculating a risk perception accuracy score, a risk perception speed score and an average driving speed of the driver in each VR road traffic risk driving scene, and calculating a risk perception ability score of the driver in each driving scene one by one; and carrying out weighted average calculation on the risk perception ability scores in all driving scenes to obtain a comprehensive risk perception ability score of the driver. The method has the advantages of accurate evaluation, simplicity, easiness in understanding and the like.

Description

technical field [0001] The invention relates to the technical field of driver safety risk management, in particular to a virtual reality-based driver risk perception ability evaluation system and method. Background technique [0002] Drivers are the primary factor affecting road traffic safety, and good risk perception ability is one of the basic quality requirements for drivers to avoid road traffic accidents and achieve safe driving. Many road traffic accidents occur because drivers fail to perceive the risks in the traffic environment in advance and fail to take evasive measures in time. At present, questionnaires, pictures, videos and other methods are commonly used to evaluate the driver's risk perception ability. On the one hand, these evaluation methods cannot provide the driver with a good sense of immersion, and on the other hand, they are quite different from the actual driving operation and driving state. , the accuracy rate is poor, thus affecting the reliabilit...
