Title:
CONSTRUCTION MACHINE, AND WORK SITE-ADAPTIVE SYSTEM
Document Type and Number:
Japanese Patent JP2023013028
Kind Code:
A
Abstract:
To provide a technology that enables highly accurate construction in construction areas with various ground properties.SOLUTION: A construction machine comprises: a vehicle body having a work device and a driving device driving the work device; a plurality of sensors detecting a state of the work device and a state of the driving device; and a controller generating a control signal for driving the driving device. The controller includes: a planning portion deciding a control instruction of the driving device according to a construction instruction input from the outside of the controller and sensor information output from the plurality of sensors; a site-adaptive processing portion selecting a control parameter set value corresponding to a ground property closest to a ground property of a construction area to be constructed among a plurality of control parameter set values optimized for each of a plurality of ground properties; and a control portion forming the control signal based on the control instruction decided by the planning portion, the sensor information, and the control parameter set value selected by the site-adaptive processing portion.SELECTED DRAWING: Figure 2
