acquiring a current position of an own vehicle;
acquiring a captured image representing an environment in front of the own vehicle from a camera;
determining whether or not a current position of the own vehicle is within a high-definition map-available region in which high-definition map information is available;
when determining that a current position of the own vehicle is within the high-definition map-available region, performing acceleration/deceleration control to control acceleration or deceleration of the own vehicle, based on specified speed information acquired by recognizing a speed sign in the captured image or specified speed information acquired from the high-definition map information based on a current position of the own vehicle 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 to an outside, terminating the acceleration/deceleration control based on the specified speed information at a point before a point at which the own vehicle leaves the high-definition map-available region to an outside and also switching the specified speed information to specified speed information acquired from road map information, the road map information having lower precision than the high-definition map information, based on a current position of the own vehicle and notifying the driver of the acquired specified speed information at a point before a point at which the own vehicle leaves the high-definition map-available region to an outside.
