Title:
WORK MACHINE AND METHOD FOR CONTROLLING WORK MACHINE
Document Type and Number:
WIPO Patent Application WO/2023/286443
Kind Code:
A1
Abstract:
This work machine comprises a vehicle body, travel wheels, a steering member, an actuator, and a controller. The steering member can be operated in a left steering range, a right steering range, and a neutral range. When the steering member is located in the neutral range, the actuator causes the steering angle of the travel wheels to be a prescribed neutral angle. In response to an operation of the steering member, the actuator changes the steering angle to the left or right from the neutral angle. When the steering member has been operated into the neutral range from the left steering range or the right steering range, the controller determines whether the steering angle has returned to the neutral angle. The controller determines, as a target direction, the direction of progression of the vehicle body when it has been determined that the steering angle has returned to the neutral angle. The controller controls the actuator so as to maintain the direction of progression of the vehicle in the target direction.
