PROBLEM TO BE SOLVED: To determine a physiological state of a crew member accurately by considering influences of a vehicle body vibration component without additionally using a sensor.SOLUTION: A state determination device system has: a respiration sensor 1 measuring a value to be measured varying according to respiration of a crew member seated on a vehicle seat S; and an ECU 2 which determines an awakening state of the crew member on the basis of a measurement result of the respiration sensor 1. The ECU 2 performs: specific processing identifying vehicle body vibration component from the varying waveform among frequency components included in the varying waveform of the measurement result of the respiration sensor 1; correction processing correcting the varying waveform on the basis of the identified vehicle body vibration component; and determination processing determining an awakening state of the crew member on the basis of the corrected varying waveform.SELECTED DRAWING: Figure 3 |
