Abstract
Provided is a travel road recognition device that can accurately recognize a travel road end of a travel road on which an own vehicle travels. A travel road recognition device of the present invention is a travel road recognition device that recognizes the travel road end of the travel road on which an own vehicletravels, and includes: a laser radarthat emits a laser bean from the own vehicletoward the travel road; a road surface determination unitthat obtains a cross slope of the travel road based on coordinate values of a point cloud obtained by the laser radar; and a road end determination unitthat obtains a change point at which a slope angle changes in the cross slope of the travel road obtained by the road surface determination unit, and obtains coordinate values of at least one travel road end of both sides in a cross direction of the travel road based on the coordinate values of the change point.
