Abstract
A controller: determines whether a current position of an own vehicle is within a high-definition map-available region in which high-definition map information is available; when the current position is within the map-available region, performs acceleration/deceleration of the own vehicle, based on specified speed information acquired by recognizing a speed sign in a captured image or acquired from the high-definition map information and also notifying a driver of the specified speed information; and when the own vehicle is predicted to leave the high-definition map-available region, terminates the acceleration/deceleration control based on the specified speed information and also acquires specified speed information from road map information, the road map information having lower precision than the high-definition map information, based on the current position of the own vehicle and notifies the driver of the acquired specified speed information before a point at which the own vehicle leaves the map-available region.
