Publication number: 20250188703Abstract: A work machine includes a vehicular body that can travel, a work implement that performs an excavation work with a bucket, and a controller. The controller includes first calculation means for obtaining mechanical data on an operation of the vehicular body and the work implement based on the mechanical data and calculating a target posture of the work implement during an excavation work and second calculation means for calculating an accelerator opening necessary for excavation of a target amount of excavated soil. The controller controls the operation of the work implement such that a posture of the work implement is set to the target posture and controls travel of the vehicular body based on the accelerator opening.Type: ApplicationFiled: January 27, 2023Publication date: June 12, 2025Applicant: KOMATSU LTD.Inventors: Motoki KOYAMA, Hiroyuki ARATAME

Patent number: 12270183Abstract: A first payload computation value which represents a weight of loads loaded on the work implement in a first attitude is obtained. The first attitude and a second attitude are equal to each other in ratio between a horizontal distance from a position of a center of gravity of a first link member to a base end of the first link member and a horizontal distance from a position of the center of gravity of the loads loaded on the work implement to the base end. A second payload computation value which represents a weight of loads loaded on the work implement in the second attitude is obtained. When the first payload computation value and the second payload computation value are determined as being different from each other, a weight of a second link member is changed and processing above is repeated.Type: GrantFiled: January 24, 2022Date of Patent: April 8, 2025Assignee: KOMATSU LTD.Inventors: Kensuke Fujii, Toshiaki Kumagai, Motoki Koyama

Publication number: 20240410135Abstract: A work machine includes a vehicular body, a work implement supported on the vehicular body, and an engine which is a drive source of the work implement. The control device of the work machine includes a rotation speed setting member manually operable for setting a target rotation speed of the engine and a controller that selectively carries out any one of ordinary control and intervention control. When ordinary control is carried out, an engine controller controls the engine at the target rotation speed based on an operation onto the rotation speed setting member. When intervention control is carried out, an intervention controller estimates contents of works by the work implement. The engine controller sets the target rotation speed corresponding to the estimated contents of works and controls the engine at the set target rotation speed regardless of an amount of operation onto the rotation speed setting member.Type: ApplicationFiled: August 24, 2022Publication date: December 12, 2024Applicant: KOMATSU LTD.Inventors: Toshiaki KUMAGAI, Ryouhei KURAMATSU, Rio KAWANA, Kensuke FUJII, Motoki KOYAMA

Publication number: 20240167247Abstract: A hydraulic excavator includes a vehicular body, a boom bottom pin supported by the vehicular body, a boom rotatably coupled to the vehicular body by the boom bottom pin, a boom top pin attached to a tip end of the boom, an arm rotatably coupled to the boom by the boom top pin, an arm top pin attached to a tip end of the arm, and a bucket rotatably coupled to the arm by the arm top pin. The computing device calculates a weight of a load conveyed by a work implement based on any two equilibrium equations of an equation of moment equilibrium around the boom bottom pin, an equation of moment equilibrium around the boom top pin, and an equation of moment equilibrium around the arm top pin.Type: ApplicationFiled: January 24, 2022Publication date: May 23, 2024Applicant: KOMATSU LTD.Inventors: Minoru SHIMIZU, Shota YAMAWAKI, Motoki KOYAMA
