Problems solved by technology

[0005] Most of the above studies focus on a single driving safety issue, and less attention is paid to the driver's overall traffic safety awareness. They lack a detailed and comprehensive safety awareness evaluation system, and there is a certain error in making judgments based on a single driving behavior. Completely and truly assess the driver's safety awareness

Embodiment Construction

[0023] The following will combine figure 1 , 2, and 3 are detailed and complete descriptions of specific embodiments of the present invention. It should be noted that all serial numbers involved in the present invention are for description only, and should not be understood as their relative importance.

[0024] The hardware equipment used in the present invention specifically includes a Logitech G29 driving simulator, a display, a HTC VIVE head-mounted display, and an EmotivEpoc mind controller. The driving simulator consists of a steering wheel, brake pedal, gear controller, and driver's seat. The steering wheel has a starter, turn signal button, hazard warning light button, and other programmable buttons.

[0025] The gear controller and the brake pedal are connected to the steering wheel through the USB interface, and then the steering wheel is connected to the PC through the USB interface. Through the interface, the steering wheel, brake pedal, gear controller and other...

Abstract

The invention discloses a driver's safety awareness evaluation method based on virtual driving and EEG detection, which mainly solves the problem of lack of comprehensive evaluation of the driver's safety awareness in the prior art. The implementation plan is: use the commercial unity3D software to build a dynamic virtual scene, and use the helmet for debugging and preview; then, in the virtual scene, use the driving simulator to collect the driver's operation data, vehicle state data and EEG signals to determine the driver's personality; According to the designed questionnaire, the scoring weight of driving operation in a certain scene is calculated; the driver's safety awareness is scored comprehensively through the neural network model. The present invention can display the personal safety awareness level of the driver, and the safety awareness level of the individual compared with the average level, and give suggestions that the driving group that is below the average level is temporarily not suitable for driving alone, and can be used in a virtual driving environment An analysis experiment of the driver's driving operation and the state of the EEG signal.

Description

technical field [0001] The invention relates to the technical field of experimental equipment, in particular to a driver's safety awareness evaluation method, which can be used in an analysis experiment of a driver's driving operation and the state of an electroencephalogram signal in a virtual driving environment. Background technique [0002] With the increase of vehicles in recent years, traffic accidents occur frequently. According to the statistics of my country's China Road Traffic Safety Blue Book, the traffic safety awareness of our citizens is generally weak. Traffic accidents caused by human factors account for the largest proportion of the total number of traffic accidents. It can be seen that improving the safety awareness of drivers is the primary means of reducing traffic accidents. At the same time, there are more than 160,000 traffic accidents in my country every year, of which 35.7% are caused by emotional instability of drivers, and driver anxiety has also...
