The present invention is provided with: position detection means (10, 20) that detect a travel lane and the position of an own vehicle; a determination means (63) that determines whether there is a need to change lanes from the travel lane detected by the position detection means (10, 20) toward a junction or an intersection that is on a travel route; and a guidance means (64) that gives guidance on changing lanes. When the determination means (63) has determined that there is a need to change lanes from the travel lane multiple times in succession, the guidance means (64) begins giving guidance at a point at which the distance from the position of the own vehicle to the junction is shorter than a distance that is found by multiplying a prescribed distance by the number of lane changes. |
