WORK MACHINE, AND METHOD AND SYSTEM FOR CONTROLLING WORK MACHINE

A work machine includes a vehicle body, a traveling wheel, a steering actuator, an articulation actuator, an articulation angle sensor, and a controller. The vehicle body includes a rear frame and a front frame. The front frame is connected so as to be able to articulate left and right with respect to the rear frame. The traveling wheel is supported by the vehicle body. The steering actuator steers the traveling wheel to the left or right. The articulation actuator changes an articulation angle between the rear frame and the front frame. The articulation angle sensor detects the articulation angle. The controller performs an automatic steering control that automatically steers the traveling wheel by controlling the steering actuator. The controller acquires the articulation angle. The controller limits travel of the vehicle body or limits the automatic steering control according to the articulation angle.
