Summary
This paper addresses the critical issue of traffic safety, specifically focusing on driver fatigue and comfort as primary contributors to accidents. With rising car ownership in China, there is an urgent need for methods to monitor driver states in real-time to prevent incidents. The authors propose that monitoring brain waves (EEG) offers a viable solution to assess driver fatigue and comfort levels under varying conditions. The research aims to design and describe a virtual driving experiment platform that integrates EEG acquisition with a simulated driving environment, allowing for the analysis of how different variables—such as weather, road conditions, and seat ergonomics—affect driver physiology. The system architecture consists of five integrated units: the subject wearing a dedicated EEG cap, an adjustable driver’s seat, a signal acquisition and amplification unit, a signal processing computer, and a three-screen splicing display for the virtual environment. The data cycle begins with the subject’s driving activity inducing changes in cortical potentials, which are captured by high-sensitivity electrodes. The EEG device supports eight analog input channels, digitized at 16-bit resolution with a fixed sampling rate of 256 Hz. These signals are transmitted via Bluetooth to the main computer, where they undergo a four-step processing pipeline: signal preprocessing, feature extraction, feature selection, and classification. The resulting analysis is stored and fed back to the virtual driving system for real-time display. The platform allows for the manipulation of specific variables to study their impact on EEG patterns. Notably, the adjustable seat permits horizontal, height, and angle adjustments, enabling researchers to correlate seat position with driver fatigue and comfort indices. The virtual driving interface simulates various scenarios, including different road environments, weather conditions like rain, and sudden obstacles. The system can also simulate driver states, such as drowsiness, to observe corresponding changes in driving performance metrics like braking timeliness and lane-changing accuracy. The activity diagram illustrates the flow from subject interaction to EEG acquisition, Bluetooth transmission, computer processing, and final feedback to the virtual display. The significance of this work lies in its potential to improve vehicle design and driver safety systems. By establishing correlations between specific driving conditions, seat ergonomics, and EEG-based fatigue markers, the platform provides practical insights for automakers regarding seat design and comfort. Furthermore, the real-time analysis capability supports the development of early warning systems for fatigue, offering a proactive approach to reducing traffic accidents. The study demonstrates a functional integration of brain-computer interface technology with driving simulation, creating a robust tool for future research into human factors in driving safety.
