The Research on Driver's Attention Recovery Based on Various Driving Conditions

To study the effect of subliminal vibration to recover young drivers' attention, fifteen subjects were selected to carry out simulated driving experiments. Focusing on driving (single driving), distracted driving, dominant vibration warning driving and subliminal vibration warning driving were carried out respectively. ECG signal and driving performance of subjects were recorded under these four kinds of driving conditions. ECG signal was analyzed using MATLAB.The results indicate that compared with ECG data of single driving the increasing amplitude of subliminal vibration warning is lower than those of the other warming methods, and the driving performance of subliminal vibration warning is better than those of other warning methods. Therefore, subliminal vibration warning can effectively recover the driver's attention. It also provides a reference for the future research on the road traffic safety system.
