Patent number: 10443214Abstract: A control system for a work vehicle includes at least one sensor, an operating device, and a controller. The operating device includes at least one operating member. The controller is programmed to control a work implement of the work vehicle based on signals from the at least one sensor and the operating device. The controller is further programmed to use the signals to obtain a distance between the work implement and a design terrain which represents a target shape of a work object, and to determine whether a surface compaction determination condition indicating that work performed by the work implement is surface compaction work is satisfied. The controller executes a surface compaction control in which a velocity of the work implement toward the design terrain is limited in response to the distance between the work implement and the design terrain when the surface compaction determination condition is satisfied.Type: GrantFiled: September 14, 2017Date of Patent: October 15, 2019Assignee: KOMATSU LTD.Inventors: Yuki Shimano, Jin Kitajima, Yoshiki Kami, Masashi Ichihara

Patent number: 10364546Abstract: A distance obtaining unit obtains the distance between a work implement and a design terrain. A work aspect determining unit determines a work aspect by the work implement. A limit velocity deciding unit limits the velocity of the work implement when the distance between the work implement and the design terrain becomes smaller. When the work aspect is surface compaction work and the distance between the work implement and the design terrain is within a first range of at least a portion that is equal to or less than a predetermined first distance, the limit velocity deciding unit increases the limit velocity of the work implement in comparison to when the work aspect is an aspect of a work other than surface compaction, or cancels the limiting of the velocity of the work implement.Type: GrantFiled: March 17, 2016Date of Patent: July 30, 2019Assignee: KOMATSU LTD.Inventors: Yuki Shimano, Tomohiro Nakagawa, Masashi Ichihara, Jin Kitajima
