摘要

Five drivers are selected to try on prairie highway landscape environment with the limited speed and free speed through grassland test road section in outdoor experiment when driving. The trend of different temperament type drivers' heart rate variability (HRV) is studied. In the indoor experimental section, the subject watches the video of secondary roads of provincial highway 101 lines about Saihantala to Mandulatu road segment in limited speed test of outdoor experiment. Tester use RM6240B multi-channel physiological signal acquisition and processing system to collect the subject's physiological signals (ECG, eye signals) for continuous acquisition. Research finding shows that the state of driving fatigue and behavior of passing the roll can be characterized by HRV. The characteristics of changes in HRV about mucus quality driver are different from the sanguine driver. The driving speed can affect the values of driver' HRV. By comparing with outdoor and indoor experiments, the values of HRV are affected by environment, driving behavior, driving speed and age. And the SDNN of HRV can be reported driver's fatigue state and changes of environment combined with the questionnaire. The values of SDNN in all of table are less than medically recommended values. It may be caused by different position of tester. It has no standard to determine values of SDNN which can reflect the fatigue now.
