A controller acquires a target design surface, at least a portion of which is located above an actual topography. The controller acquires a position of a main body of a work machine. The controller acquires a position of a work implement. The controller causes the work machine to travel forward while controlling the work implement in accordance with the target design surface. The controller acquires a height difference between the target design surface and a predetermined portion of the main body. The controller determines whether there is any more earth held by the work implement based on the height difference.

System for controlling work machine, method, and work machine

A controller determines that a signal from an operating device represents either a normal operation to manually control a blade or a trigger operation to automatically control the blade. The controller moves the blade so that the angle of the blade is changed in accordance with the operation of the operating device when the signal from the operating device is determined as representing a normal operation. The controller moves the blade until the angle of the blade reaches a predetermined target angle when the signal from the operating device is determined as representing the trigger operation while the bulldozer is traveling.

System and method for controlling bulldozer

A controller controls the steering device so as to cause a vehicle body to turn toward the left when a left steering lever is operated without a right steering lever being operated. The controller controls the steering device so as to cause the vehicle body to turn toward the right when the right steering lever is operated without the left steering lever being operated. The controller reduces the rotation speed of the engine when both the left steering lever and the right steering lever are operated and both the operation amount of the left steering lever and the operation amount of the right steering lever are equal to or greater than a first threshold.

Work vehicle and control method for work vehicle

When left and right steering levers are both operated and the operation amount of the left lever is larger than that of the right lever, a controller calculates a correction left operation amount of the left lever according to the operation amount of the right lever, and controls a left steering clutch so as to cause a vehicle body to turn toward the left in accordance with the correction left operation amount. When left and right steering levers are both operated and the operation amount of the right lever is larger than that of the left lever, the controller calculates a correction right operation amount of the right lever according to the operation amount of the left lever, and controls a right steering clutch so as to cause the vehicle body to turn toward the right in accordance with the correction right operation amount.
