Abstract:

In the human-machine co-driving stage, the drivers' hazard perception of driving environment at a high level is the core to ensure timely, effective, stable, safe takeover. In this study, the driving behaviors and electroencephalogram (EEG) responses of drivers in typical vehicle-to-powered two-wheeler crash scenarios are obtained by conducting the hazard perception simulation driving tests. From the perspective of driving behaviors, a quantitative model of drivers' hazard perception is built through quantile regression with the braking TTC (Time to Collision) and average acceleration as evaluation indexes. Through independent sample test, it is found that the driving experience and collision scenario types have a significant impact on drivers' hazard perception. From the perspective of EEG responses, it is found that the Alpha band is significantly correlated with hazard perception ability through double independent sample test and FDR correction. Furthermore, the drivers' hazard perception neural mechanism is proposed, including two stages of visual perception and cognitive processing. The research results contribute to improving the safety of human-machine co-driving vehicles.
