Abstract: In the light of data of the experimental test, changing rules of variation coefficient of the three typical brain waves are analyzed. Variation regulations of the linear and nonlinear characteristics of heart rate variability (HRV) indexes are analyzed. Quantities relationship among the amount of original fatigue, cumulative amount of driving fatigue and fatigue accumulation is analyzed based on the variation coefficient of R-R interphase. The S-curve model of driving fatigue accumulation is established for describing the diversification of driving fatigue accumulation over the time. Physiological fatigue degree is defined for determining the key indicator of physiological characteristic measurement on the status judgment of driver fatigue. The conclusion can be applied to fatigue driving monitoring.
