Driver Sleepiness Level Detection Based on the Heart Rate Variability

This paper reports on a study of technology that can be used to monitor vehicle drivers based on a frequency analysis of their heart rate variability and power spectrum density. The authors first developed a system to detect driver sleepiness. Using a steering wheel sensor to get a heartbeat signal, they can detect the early signs of drowsiness and cope with individual differences through a unique coordinated analysis of the two axes denoted by the driver’s excitement level and awareness level. This monitor was compared with video images of the drivers under simulation conditions, to test the validity of the heart rate monitoring system. The authors conclude that this technology can successfully be used to detect drivers’ sleepiness before critical situations arose.
