Patent number: 11674287Abstract: A controller obtains topographical data indicative of the topography of a work site. The controller obtains material data indicative of the position of a material. The controller computes an evaluation function based on the material data for each of a plurality of candidates of the travel path to be decided from the topographical data. The evaluation function includes a material function pertaining to an amount of the material. The controller decides a candidate having a smallest evaluation function of the plurality of candidates as the travel path.Type: GrantFiled: December 10, 2018Date of Patent: June 13, 2023Assignee: KOMATSU LTD.Inventors: Masami Hirayama, Jose Guivant, Jayantha Katupitiya, Mark Whitty

Publication number: 20220389679Abstract: A controller determines a plurality of candidate paths. The plurality of candidate paths cross a first digging wall from a first slot toward a second slot and extend in respective directions. The controller calculates an evaluation function of a path search algorithm for each of the plurality of candidate paths. The controller determines a candidate path having an optimal evaluation function of the plurality of the candidate paths as a first digging path. The controller controls a work machine according to the first digging path.Type: ApplicationFiled: December 7, 2020Publication date: December 8, 2022Inventor: Masami HIRAYAMA
