DEVICE FOR DETERMINING BIOLOGICAL STATE DURING DRIVING AND COMPUTER PROGRAM

摘要

A device determining a biological state of a driver more accurately, including a hypnagogic symptom phenomenon detecting mechanism, an imminent sleep phenomenon detecting mechanism, a subjective sleepiness/low consciousness traveling state detecting mechanism, and a homeostasis function level determining mechanism, which are configured to function in parallel. Therefore, detection of a hypnagogic symptom phenomenon or an imminent sleep phenomenon, or detection of a period resisting a light sleepiness mild sleepiness or a strong sleepiness which occurs consciously, or the case where a low consciousness traveling state due to a decrease in consciousness level momentarily occurs or the case where it occurs longer continuously, or the like, can be determined/detected, and the driver's biological state can be accurately determined

主权项

1. A device for determining biological state during driving, the device determining a biological state of a driver in a driving environment by using a biosignal sampled from a back of the driver by a biosignal measuring device provided in a driver's seat, the device comprising:
an analyzing and calculating means performing a predetermined calculation by using a time series waveform of the biosignal; and a determining and detecting means determining or detecting the biosignal by using a calculation result of the analyzing and calculating means, wherein the determining and detecting means comprises: a hypnagogic symptom phenomenon detecting means detecting a hypnagogic symptom phenomenon which is a physical condition change phenomenon before falling asleep; an imminent sleep phenomenon detecting means detecting an imminent sleep phenomenon which is a physical condition change phenomenon before falling asleep occurring after the hypnagogic symptom phenomenon occurs; a subjective sleepiness/low consciousness traveling state detecting means detecting a subjective sleepiness which is being conscious of a sleepiness by oneself or a low consciousness traveling state due to a decrease in consciousness level; and a homeostasis function level determining means determining a level of adaptation ability of a homeostasis function, wherein the hypnagogic symptom phenomenon detecting means, the imminent sleep phenomenon detecting means, the subjective sleepiness/low consciousness traveling state detecting means and the homeostasis function level determining means are configured to function in parallel.
