  • Publication number: 20240247466
    Abstract: A work machine includes a vehicle body, a steering control wheel, an actuator, and a controller. The vehicle body includes a rear frame and a front frame coupled to the rear frame so as to turn with respect to the rear frame. The steering control wheel is supported by the front frame. The actuator changes a steering angle of the steering control wheel. The controller controls the actuator. The controller determines a target direction in which the vehicle body travels, acquires an articulate angle of the front frame with respect to the rear frame, and sets the steering angle so that the vehicle body moves in the target direction by controlling the actuator in accordance with the articulate angle.

  • Publication number: 20240241765
    Abstract: In prediction processing, the controller predicts a temporal change in a calculation capability available in grid computing processing of each of a plurality of arithmetic devices. In the request processing, in a case where the calculation capability of the arithmetic device predicted to be available in the grid computing processing on the basis of a result of the prediction processing is insufficient, the controller presents, to a user who owns another arithmetic device except for the arithmetic device predicted to be available in the grid computing processing among the plurality of arithmetic devices, request information for prompting provision of the calculation capability of the another arithmetic device to the grid computing processing.

  • Publication number: 20240229419
    Abstract: A work machine including a vehicle body, a traveling wheel, first and second steering members, an actuator, first and second operation sensors that output operation signals indicative of operation of the first and second steering members, and a controller. The controller acquires the first and second operation signals. The controller determines whether or not the first steering member is being operated, and whether the first steering member was operated last. The controller performs an automatic control of the actuator to set the steering angle to a target angle upon determining that the first steering member is not being operated and the first steering member was operated last. The controller does not perform the automatic control upon determining that the second steering member was operated last even if the first steering member is not being operated.

  • Publication number: 20240218633
    Abstract: A work machine includes a vehicle body, traveling wheel, steering member, actuator, operation sensor, steering angle sensor, direction sensor, and a controller. The steering member is operable between left, right, and neutral steering ranges. The actuator sets a steering angle of the traveling wheel to a neutral angle when the steering member is in the neutral range, and changes the steering angle to left or right in response to operation of the steering member. The controller acquires operation, angle, and direction signals from the sensors. The controller determines whether the steering angle has returned to the neutral angle when the steering member has been operated from the left or right steering ranges to the neutral range. The controller determines the traveling direction when the steering angle has returned to the neutral angle, as a target direction. The controller controls the actuator to hold the traveling direction in the target direction.
