摘要：

PROBLEM TO BE SOLVED: To accurately determine the consciousness deteriorating state of a driver.

SOLUTION: A frequency analyzing part 18 calculates a power value fiof each frequency band i from the time series data s of a steering angle signal input from a steering angle sensor 12, and a total power value calculation part 22 reads weighting factor wishowing a large value from a weighting factor DB 20 according as the level of difference between a power value ldiin a frequency band i when drivers consciousness deteriorates and a power value in the other frequency band and the level of difference between a power value when the drivers consciousness deteriorates and a power value when the driver is awakened in the same frequency band is large, and multiplies the power value fiof each frequency band i by the weighting factor wi, and calculates a total power value p by adding the value of wi×fiof each frequency band for prescribed frequency bands, and a determination part 24 calculates a cumulative value (a) of a total power value p, and determines whether or not the cumulative value (a) is larger than a prescribed value to determine the consciousness deteriorating state of the driver.
