Abstract: A method to measure a driver|s mental and physical load directly has been considered as an effective tool for the development of a comfortable and safe vehicle, and attempts have been made to use various physiological reactions as objects. This paper reports on one method which uses |Heart Rate Variability (HRV)|. Reasons for using HRV have already been reported by some research institutes. In this study, the method of calculating HRV has been improved for use in the analysis of a driver|s heartbeat during driving, and the potential of HRV as a tool to quantify a driver|s tension and fatigue has been confirmed experimentally.
Keywords: driver comfort; driver fatigue; heart rate variability; human engineering; driver tension; vehicle evaluation; vehicle safety; mental load; physical load; driver heartbeat.
