Patent attributes
An autonomous drive instruction device shortens the time required for vehicles to arrive at a designated location from a parking location in a parking lot without a navigation map. The autonomous drive instruction device includes a travel-direction determiner and an autonomous drive instructor. The travel-direction determiner determines one path as the travel direction of the vehicle on the basis of the designated location and information on paths in a branch area. The one path corresponds to an extension direction that forms a smaller one of angles formed by extension directions of the paths from the branch area and a designated-location direction from the branch area to the designated location. The autonomous drive instructor outputs instruction information including information on the travel direction to the autonomous drive control device such that the autonomous dive control device controls the vehicle to move in the travel direction by autonomous driving.
