    摘要: A vehicular travel guidance apparatus and method are provided. The apparatus includes a map image display unit that displays a map image on a display device and a maximum energy amount acquisition unit that acquires a maximum charging energy amount of an in-vehicle battery. The apparatus further includes a charging facility information acquisition unit that acquires information regarding a charging facility capable of charging the in-vehicle battery. Also included is a travelable area acquisition unit that acquires a travelable area, within which the vehicle is able to travel from the charging facility by consuming an energy amount corresponding to a predetermined percentage of the maximum charging energy amount. The apparatus also includes a display mode change unit that varies a display mode of the map image based on the acquired travelable area.

    摘要: A road information acquisition device includes: a surface elevation acquisition unit that obtains a surface elevation; a road information acquisition unit that calculates first road information relating to a travel route to be traveled by a host vehicle on the basis of the surface elevation; and a structure determination unit that determines whether or not a structure exists on the travel route, wherein, when the structure determination unit determines that the structure exists on the travel route, the road information acquisition unit obtains second road information, which is different from the first road information, relating to a point at which the structure exists on the travel route.
