Embodiment Construction

[0042] Modes (embodiments) for carrying out the present invention will be described in detail with reference to the drawings.

[0043]

[0044] figure 1 It is a perspective view of the working machine of the embodiment. figure 2 It is a block diagram showing the configuration of the hydraulic system 300 and the control system 200 of the hydraulic excavator 100 . A hydraulic excavator 100 as a working machine has a vehicle body 1 and a work implement 2 as a main body. The vehicle body 1 has an upper revolving body 3 as a revolving body and a traveling device 5 as a traveling body. The revolving super structure 3 accommodates devices such as an engine and a hydraulic pump as a power generating device inside the machine room 3EG. The machine room 3EG is disposed on one end side of the upper revolving structure 3 .

[0045] In the embodiment, the hydraulic excavator 100 uses an internal combustion engine such as a diesel engine as an engine as a power generation device, but...

Abstract

A work-machine control system that controls a work machine provided with a work device that has a boom, an arm, and a bucket. Said work-machine control system includes the following: a position detection apparatus that detects the position of the work machine, yielding position information; a generation unit that determines the position of the work device on the basis of the position information from the position detection apparatus and generates, from pre-prepared design-plane information, excavation-topology-goal information that indicates a shape goal for the excavation target of the work device; and a work-device control unit that, on the basis of the position of the work device and the excavation-topology-goal information, which are acquired from the generation unit, executes excavation control that prevents the work device from digging beyond the aforementioned shape goal. During the execution of said excavation control, if unable to acquire the excavation-topology-goal information, the work-device control unit continues the excavation control using excavation-topology-goal information from before the point in time at which the work-device control unit became unable to acquire the excavation-topology-goal information.

Description

technical field [0001] The present invention relates to a control system of a work machine including a work machine, a control system of the work machine, a hydraulic excavator, and a control method of the work machine. Background technique [0002] Conventionally, in a construction machine including a front device including a bucket, excavation control for moving the bucket along a boundary surface representing a target shape of an excavation object has been proposed (for example, refer to Patent Document 1). [0003] prior art literature [0004] patent documents [0005] Patent Document 1: International Publication No. WO95 / 30059 [0006] In excavation control, a boundary surface representing a target shape of an excavation target is generated based on, for example, position information of the work machine based on position data received from a positioning satellite or the like. Therefore, since the excavation control cannot be continued when the position information o...
