Abstract
A map management apparatus includes an image recognition unit that recognizes at least any one of a road shape, a road type, and a speed sign on the basis of a captured image of an in-vehicle camera, a recognition determination unit that determines whether or not there is a difference between the recognized recognition information and map information, a vehicle speed determination unit that determines whether or not there is a difference between a speed of an own vehicle and speed sign information included in the map information, and a notification unit that issues a notification for prompting update of the map information when the number of times when the recognition determination unit determines that there is the difference and the vehicle speed determination unit determines that there is the difference becomes equal to or more than a determination frequency threshold.
