Notification device

A notification device that executes a notification to a driver of an own vehicle, the notification device comprising:

• a speed limit recognition unit that recognizes a speed limit of a traveling region in which the own vehicle travels based on at least one of a captured image of a camera of the own vehicle and a map database;
• a traveling speed recognition unit that recognizes a traveling speed of the own vehicle based on a detection result of an internal sensor of the own vehicle;
• a cumulative value calculation unit that calculates a cumulative value of speed limit excess traveling in a state in which the traveling speed of the own vehicle exceeds the speed limit;
• and
• a notification control unit that executes a speed limit excess notification to the driver of the own vehicle at a timing at which the traveling speed of the own vehicle reaches a predetermined threshold, when the traveling speed of the own vehicle exceeds the speed limit, wherein the notification control unit increases the predetermined threshold as the cumulative value of speed limit excess traveling increases.
