Problems solved by technology

[0007] Such conventional techniques for determining a driver's state may be based on changes in the shape of feature points in his or her face due to drowsiness, and may fail to detect that there is no change in the shape of each eye (e.g., eyes closed). phenomenon) or impaired drivers with no change in the shape of the mouth (e.g., yawning)

Abstract

The present invention provides a system for determining the state of a driver, comprising: a face tracking device configured to detect the coordinates and direction vectors of the face from the driver's face image at sampling time intervals; an event detection device configured to To detect a valid behavior of the vehicle as an event; and determining means configured to determine the impaired state of the driver based on the driver's reflex response time when the event is detected by the event detecting means.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application is based on and claims priority to Korean Patent Application No. 10-2017-0058783 filed in the Korean Intellectual Property Office on May 11, 2017, the entire contents of which are incorporated herein by reference. technical field [0003] The present disclosure relates to systems and methods for determining a driver's state, and more particularly, to techniques for determining a driver's state (eg, impaired state) based on the driver's reflex response time as a function of vehicle behavior. Background technique [0004] In general, a driver in a normal state may involuntarily display various reflex responses, such as the righting reflex to align his or her head with the orientation of his or her body, and to respond when he or she loses Tilt response that doesn't fall while balancing. [0005] However, if the driver is in an impaired state or fatigued due to drinking, drug use, etc., because although h...
