Abstract
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.
