Determination system of a low level of consciousness

摘要

It is an object of the invention to provide a low-awareness determination system that can detect sudden steering after a non-steering state with high accuracy. The invention provides a low awareness level determination system 1 that detects sudden steering after a non-steering state and determines a reduced consciousness state of a driver driving a vehicle. The low awareness level determination system 1 includes a curved road determining means 31 for determining whether a road on which the vehicle is traveling is a curved road and for determining whether the vehicle is on the outside of the curved road or on the inside of the curved road When the road is the curved road, road travels a threshold setting means 32 for setting different thresholds for determining a sudden steering when the curved road determining means 31 determines that the road is not a curved road when the curved road determining means determines 31 that the vehicle is running on the outside of the curved road and when the curved road determining means 31 determines that the vehicle is traveling on the inside of the curved road and a sudden steering detector 33 for Detecting the sudden steering based on the threshold values set by the threshold setting device 32 after the non-steering state is detected.
