Display device

A display device comprising:

• a road width recognition unit configured to recognize a width of a road on which a vehicle is traveling based on a detection result of a vehicle-mounted external sensor used for at least one of autonomous driving control or driving assistance control of the vehicle including a camera, the camera being configured to capture a surrounding situation image showing a situation around the vehicle;
• an occupant state recognition unit configured to recognize a state of an occupant of the vehicle based on a captured image of an in-vehicle camera configured to capture an image of the occupant of the vehicle;
• a display control unit configured to cause a vehicle-mounted display unit to display the surrounding situation image;
• and
• a surrounding object recognition unit configured to recognize an object around the vehicle based on a detection result of the external sensor,
• wherein
• the display control unit is configured to
• cause the display unit to display the surrounding situation image in response to a vehicle speed of the vehicle being equal to or less than a predetermined vehicle speed threshold and a predetermined narrow path condition being satisfied, based on at least the width of the road and the vehicle speed, and
• in response to the state recognized by the occupant state recognition unit indicating that the occupant is gazing at the display unit, keep the display unit from displaying the surrounding situation image even when the vehicle speed is equal to or less than the predetermined vehicle speed threshold and the predetermined narrow path condition is satisfied, and
• the predetermined narrow path condition is satisfied in response to
• the road being wider than a predetermined narrow path, a width of the predetermined narrow path being larger than a predetermined further narrow path threshold and equal to or less than a predetermined narrow path threshold,
• the width of the road on a front side of the vehicle decreasing in a case that a width reduction sign is present on the front side of the vehicle or in a case that map information indicating that the width of the road on the front side of the vehicle decreases, and
• at least one of an oncoming vehicle or an obstacle being present within a predetermined distance threshold on the front side of the vehicle.
