US 12,735,047 B2 · Driver psychophysiological state detection

Abstract

It is herein disclosed a method of collecting data for determining a psychophysiological state of a human driver, comprising collecting data throughout a driving session in a car simulator, wherein the driving session comprises a plurality of driving stages, wherein the plurality of driving stages comprise, at least: a first stage of driving by a driver in a first scenario; a second stage of driving by the driver in a first scenario, wherein a first cognitive test is performed by the driver simultaneously with the driving; a third stage of driving by the driver in a second scenario; a fourth stage of driving by the driver in the second scenario, wherein a second cognitive test is performed by the driver simultaneously with the driving; wherein said collecting data comprises: collecting, by a plurality of detection means, physiological data on the driver throughout the driving session; wherein the physiological data collected comprises at least one of: heart rate data, electroencephalogram (EEG) data, eye movement data, and respiration data; and collecting driver behaviour data.

A method of collecting data for determining a psychophysiological state of a human driver, comprising:

performing a driving session of a driver in a car simulator, wherein the driving session comprises:
a plurality of driving stages, the plurality of driving stages comprising:
a first stage of driving in a first scenario;
a second stage of driving in the first scenario, wherein the driver undergoes a first cognitive test simultaneously with the driving;
a third stage of driving in a second scenario;
and
a fourth stage of driving in the second scenario, wherein the driver undergoes a second cognitive test simultaneously with the driving;
wherein the first scenario simulates a driving scenario of a first level of complexity,
wherein the second scenario simulates a driving scenario of a second level of complexity higher than the first level of complexity, and
wherein each of the first and second cognitive tests is an N-back test;
the method further comprising:
collecting, throughout the driving session, physiological data on the driver and driver behavior data, wherein the physiological data comprises at least one of:
heart rate data, electroencephalogram (EEG) data, eye movement data, and respiration data, and wherein the driver behavior data is indicative of a steering wheel activity of the driver and a reaction of the driver to the cognitive tests.
