Assessment of Driving Fatigue using HRV Analysis Method 2003-01-0167

Changes in a driver's physiological variables indicate his condition. Knowing how these variables change when driving is important in measuring the driver's mental and physical fatigue caused by driving. In this study, we investigated the relationship between the number of hours of driving and characteristics of heart rate variable (HRV) signal. 5 subjects were asked to drive four different passenger vehicles on an expressway. All tests were repeated twice. The experimental number was 40 times. After 3-hours of driving, differences in the HRV signal characteristics were observed. These indicated that driving fatigue is able to detected through the HRV signal.
