Abstract
The driving assistance device includes: a fluctuation amount recognition unit; a driver abnormality recognition unit that recognizes an abnormality of a driver of another vehicle based on a captured image of an external camera provided in a vehicle; an abnormal state determination unit that determines whether the other vehicle is in a fluctuation abnormality state based on a comparison result between a fluctuation amount of the other vehicle and the fluctuation threshold; and a notification control unit that performs notification regarding the fluctuation abnormality state. The abnormal state determination unit determines whether a fluctuation abnormal state is present, with the fluctuation threshold value in a case where an abnormality of the driver of the other vehicle is recognized as a smaller absolute value than the fluctuation threshold value in a case where an abnormality of the driver of the other vehicle is not recognized.
