An end point speed v i at an end point Pi of inertial travel that a vehicle 10 is controlled to perform in a short section l i is calculated using a weight M, a start point speed v i-1 , slopes ¸ i , ¸ i-1 , and a horizontal distance x, based on a change in energy E of the vehicle 10 or an acceleration a of the vehicle 10 in the short section li. In a case where the calculated end point speed v i is within a speed range R1, the vehicle 10 is controlled to perform inertial travel in the short section l i . In this way, the speed of the vehicle in a case where the vehicle is controlled to perform inertial travel can be accurately calculated and the vehicle can be prevented from deviating from a set speed range at an early stage even when controlled to perform inertial travel, thereby increasing the distance travelled by inertial travel and effectively increasing fuel economy.
