Abstract
A driver abnormality detection device is provided that detects an abnormality sign of a driver at a sufficiently earlier stage before driving actually becomes difficult. The detection device includes a control circuit configured to detect an abnormality sign of a driver based on visual line information from a visual line detector, driving operation information from a driving operation detector, and traveling environment information from a traveling environment information detector. The control circuit is configured to calculate a visual line abnormality degree, a driving operation abnormality degree, and a traveling risk of a vehicle. The control circuit is configured to combine the visual line abnormality degree, the driving operation abnormality degree, and the traveling risk to generate a comprehensive abnormality degree, and detect the abnormality sign of the driver when the comprehensive abnormality degree is a predetermined threshold value or greater.
