WORK MACHINE AND METHOD FOR CONTROLLING WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/080113
Kind Code:
A1
Abstract:
This work machine comprises a detection unit that detects an articulation angle, a steering hydraulic cylinder, an operating device that receives input of an operator operation command for driving the steering hydraulic cylinder, a control valve that controls the drive amount of the steering hydraulic cylinder, and a controller that outputs a command current to operate the control valve in response to the operation command from the operating device. The controller executes a calibration mode for operating the control valve by correcting the command current for the operation command from the operating device, and cuts off the command current to the control valve if the articulation angle has reached or exceeded a prescribed angle in the calibration mode.
