Abstract:
Provided is at least two of a direction determination unit which determines that the state is abnormal when a gaze direction of a driver of a vehicle is not within a first predetermined range based on a captured image of a head of the driver, a height determination unit which determines that the state is abnormal when a height of an eye of the driver is not within a second predetermined range based on the captured image, and a position determination unit which determines that the state is abnormal when a position of the head in a lateral direction is not within a third predetermined range based on the captured image; and an abnormal state determination unit which determines whether the state of the driver is abnormal based on the determination results of the determination units.

Claim (Index 9):
A driver abnormality detection method executed by a driver abnormality detection device installed in a vehicle, the driver abnormality detection method comprising:\n at least two of determination steps including a direction determination step of determining that the state is abnormal when a gaze direction of a driver of the vehicle is not within a first predetermined range based on a captured image of a head of the driver, a height determination step of determining that the state is abnormal when a height of an eye of the driver is not within a second predetermined range based on the captured image, and a position determination step of determining that the state is abnormal when a position of the head in a lateral direction is not within a third predetermined range based on the captured image; an abnormal state determination step of determining that the state of the driver is abnormal when at least one of determination steps determines that the state has been abnormal continuously for a time equal to or longer than a continuation allowable time set for that determination step; an information acquiring step of acquiring a surrounding situation of the vehicle; and a time correction step of correcting the continuation allowable time set for at least one of the determination steps according to the surrounding situation acquired by the information acquiring step.
