Publication number: 20250042219Abstract: A work machine actuates a work implement with power from a battery device. The work machine includes a first region in which the battery device is disposed, a second region in which a battery thermal management system is disposed, and a vehicle body cover having a polyhedral shape and surrounding the first region and the second region. The battery thermal management system manages temperature of the battery device. In the vehicle body cover, an orientation of a surface in which a first air intake port arranged to guide air into the first region is formed, is different from an orientation of a surface in which a second exhaust port arranged to draw air out from the second region is formed.Type: ApplicationFiled: December 16, 2022Publication date: February 6, 2025Inventors: Yuki TAKASE, Ayumi OHKUMA, Yutaka TANAKA, Masaki DAIMON, Yuya HIROSE

Patent number: 12098527Abstract: A time period for which an ineffective operation is performed during an excavation work is reduced. A work machine includes a vehicular body, a running wheel rotatably attached to the vehicular body, a work implement operable with respect to the vehicular body, an operation apparatus for operating the running wheel and the work implement, and a controller that controls an operation by the work machine. The controller determines that slip-during-excavation which refers to slip of the running wheel with respect to the ground is occurring during the excavation work based on an operation command value output from the operation apparatus and outputs a signal relating to working of the work implement.Type: GrantFiled: March 14, 2019Date of Patent: September 24, 2024Assignee: KOMATSU LTD.Inventors: Masaki Daimon, Hiroyuki Aratame

Publication number: 20230106835Abstract: A target posture for a work implement at work is determined. There is provided a working system, comprising a body, a work implement attached to the body, and a computer. The computer has a trained target posture estimation model to determine a target posture for the work implement to assume at work. The computer obtains a target value for an amount of a work performed by the work implement, a period of time elapsing since the work implement started to work, and mechanical data for operation of the body and the work implement, uses the trained posture estimation model to estimate a target posture from the target value, the elapsed period of time and the mechanical data, and thus outputs the estimated target posture.Type: ApplicationFiled: March 4, 2021Publication date: April 6, 2023Applicant: KOMATSU LTD.Inventors: Minoru SHIMIZU, Hiroyuki ARATAME, Masaki DAIMON

Publication number: 20230080719Abstract: A manipulation system is provided that is used to guide an operator to manipulate a manipulation member. The manipulation system comprises a plurality of types of manipulation members manipulated by an operator of a work machine to operate the work machine, and a memory that stores model data for each type of manipulation member as a model in manipulating the manipulation members.Type: ApplicationFiled: March 4, 2021Publication date: March 16, 2023Applicant: KOMATSU LTD.Inventors: Minoru SHIMIZU, Nobuyoshi YAMANAKA, Masaki DAIMON, Hiroyuki ARATAME

Publication number: 20230068838Abstract: An operator is allowed to easily recognize a difference between a manipulation actually performed when performing a work and a manipulation serving a model for the work. A manipulation guide device for a work machine includes a manipulation device, a storage unit, and a display unit. The manipulation device is manipulated by an operator of the work machine to operate the work machine. The storage unit stores model data serving as a model when the manipulation device is manipulated. The display unit displays a change over time in a result of comparison between actual manipulation data about an actual manipulation of the manipulation device by the operator and model data in a time period during an operation of the work machine.Type: ApplicationFiled: March 4, 2021Publication date: March 2, 2023Applicant: KOMATSU LTD.Inventors: Minoru SHIMIZU, Nobuyoshi YAMANAKA, Masaki DAIMON, Hiroyuki ARATAME
