Abstract:
1. A working unit control system comprising: a working unit including a boom rotatably attached to a vehicle main body, an arm rotatably attached to the boom, and a bucket rotatably attached to the arm; an operating tool configured to receive a user operation to drive the working unit, the operating tool being configured to output an operation signal in accordance with the user operation, the operating tool including an arm operating lever configured to receive the user operation to drive the arm; a work type determining part configured to determine that a work type of the working unit corresponds to a shaping work when an arm operation signal outputted in response to an operation of the arm operating lever for operating the arm is included in the operation signal, the work type determining part configured to determine that the work type of the working unit corresponds to a cutting edge aligning work when the arm operation signal is not included in the operation signal; and a drive controlling part configured to operate the working unit in a shaping mode when the work type determining part determines that the work type corresponds to the shaping work and operate the working unit in a cutting edge aligning mode when the work type determining part determines that the work type corresponds to the cutting edge aligning work, the drive controlling part being configured to automatically move the bucket along a designed surface when the working unit is operated in the shaping mode, the drive controlling part being configured to automatically stop the bucket in a predetermined position set with reference to the designed surface when the working unit is operated in the cutting edge aligning mode, the designed surface indicating a target shape of an excavation object.
