Abstract: A route generation device for an autonomous mobile body 1 is configured to generate a route for the autonomous mobile body 1 based on a cost map of a way serving as the route for the autonomous mobile body 1, the cost map including a plurality of grid cells M1 to M9 into which the cost map is divided. In the cost map, a center of a road RD is assigned with a lower value of cost than an edge zone of the road RD. The route generation device includes a controller that is configured to update the cost map based on a result of detection by an outside recognition device, and generate a route based on the updated cost map.

Abstract: An autonomous mobile body control device includes a control unit that is capable of executing a first movement control that controls movement of an autonomous mobile body on the basis of a main map, and a second movement control that controls the movement of the autonomous mobile body on the basis of a local map. In the case that a map used when causing the autonomous mobile body to move is switched from the main map to the local map, or alternatively, in the case that the map used when causing the autonomous mobile body to move is switched from the local map to the main map, the control unit temporarily executes a third movement control that controls the movement of the autonomous mobile body on the basis of a landmark appearing in an acquired image.
