Abstract
Problem to be solved: Provided is a travel route generation method that is for an autonomous vehicle and enables a travel route to be accurately generated, even in a case where positioning using GPS or the like is unavailable and the boundary of a travel path is unclear. Solution: Scene information that includes a travel path is obtained by sensing surroundings of the autonomous vehicle, a boundary of the travel path is detected based on the obtained scene information, a likelihood based on machine learning is used to evaluate the detected boundary, and a provisional travel route on the travel path for the autonomous vehicle is generated based on the boundary and in accordance with the likelihood for the boundary.
