A final point speed (vi) at a final point (Pi) of inertial travel that a vehicle (10) is caused to perform in a short section (li) is calculated using a weight (M), a start point speed (vi-1), a slope (θi), (θi-1), and a horizontal distance (Δx), on the basis of a change in energy (E) of the vehicle (10) or an acceleration (a) of the vehicle (10) in the short section (li). When the calculated final point speed (vi) is within a speed range (R1), the vehicle (10) is controlled to perform inertial travel in the short section (li). In this way, the speed of the vehicle when caused to perform inertial travel can be accurately calculated, the vehicle can be prevented from deviating from a set speed range early even when caused to perform inertial travel, and the distance travelled by inertial travel can be increased, whereby fuel economy can be effectively increased. |
