FATIGUE ESTIMATION DEVICE AND FATIGUE ESTIMATION METHOD FOR DRIVER

摘要

PROBLEM TO BE SOLVED: To more accurately estimate a fatigue state of a driver.

SOLUTION: A fatigue estimation means 106 estimates the fatigue state of the driver based on a state of hardness estimated by a hardness estimation means 102 and estimation values obtained by an estimation value calculation means 105. The fatigue estimation means 106 compares respective properties of the plurality of estimation values and a state property (a frequency property) of the hardness of the hardness estimation means 102 about the plurality of estimation values estimated from the estimation value calculation means 105, and selects the estimation value of a property most approximate to the state property of the hardness. The fatigue estimation means 106 estimates the fatigue state of the driver from the selected estimation value.
