Physiological condition estimation device and vehicle control device

The physiological condition estimation device comprising:

• an eye-open time acquiring unit that acquires an eye-open time of a target person;
• a variation acquiring unit that acquires a variation in the eye-open time acquired by the eye-open time acquiring unit;
• and
• a physiological condition determining unit that determines a physiological condition of the target person on the basis of the variation in the eye-open time acquired by the variation acquiring unit,
• wherein the physiological condition determining unit determines that the attentiveness is reduced before the target person reaches a drowsy condition, and
• the physiological condition determining unit determines the attentiveness reduction on the basis of the variation in the eye-open time being equal to or more than an attentiveness reduction threshold value.

A physiological condition estimation device comprising:

• an eye-open time acquiring unit that acquires an eye-open time of a target person;
• a variation acquiring unit that acquires a variation in the eye-open time acquired by the eye-open time acquiring unit;
• and
• a physiological condition estimating unit that estimates a physiological condition of the target person on the basis of an amount of change of the variation in the eye-open time acquired by the variation acquiring unit with respect to time.
