To solve a problem that smooth traveling after traveling through continuous specific zones has been impracticable, on a road with continuous specific zones where traveling at a specific target vehicle speed is desired.
Information pertaining to a first zone set ahead of a host vehicle and a second zone farther ahead than the first zone is acquired. Based on the information, if a distance between an end point of the first zone and a start point of the second zone is shorter than a distance within which the host vehicle can be slowed at predetermined deceleration to a second target vehicle speed for traveling the second zone at the start point of the second zone, a second acceleration gear ratio is acquired for accelerating the host vehicle in a second acceleration zone following the second zone. The gear ratio of the host vehicle is set to the second acceleration gear ratio in a first deceleration zone for slowing the host vehicle before reaching the first zone.
