CPC E02F 3/437 (2013.01) [E02F 3/439 (2013.01); E02F 9/262 (2013.01); E02F 9/265 (2013.01); E02F 9/2029 (2013.01); E02F 9/2033 (2013.01)] | 5 Claims |
1. A work machine comprising:
a multi-joint work implement that forms a target surface with a bucket;
a plurality of hydraulic actuators that drive the work implement;
a controller that is configured to calculate a control command for at least one of the plurality of hydraulic actuators to hold an operation locus of the bucket above the target surface on a basis of a distance from the work implement to the target surface, and to control the at least one of the hydraulic actuators on a basis of the control command; and
a communication device that performs bidirectional communication with a management server,
wherein the controller
transmits work situation parameters of the work machine to the management server,
receives, from the management server, a control command correction value that is computed by the management server on a basis of the work situation parameter and that represents a correction value for correcting the control command, and
controls the at least one of the hydraulic actuators with a corrected control command that represents the control command corrected on a basis of the control command correction value, wherein the controller is configured to calculate an average claw tip error value that represents an average value of differences between the target surface and the operation locus of a claw tip of the bucket when the controller controls at least one of the hydraulic actuators on a basis of the corrected control command, and to transmit the calculated average claw tip error value to the management server, and
the control command correction value is adjusted on a basis of the average claw tip error value transmitted to the management server in a past.
