  • Patent number: 11168458
    Abstract: A work vehicle includes a work implement and a controller. The work implement includes a vehicular body that travels in excavation, a boom pivotable with respect to the vehicular body, and a bucket pivotable with respect to the boom. The controller calculates a direction of a cutting edge of the bucket, determines a direction of movement of the cutting edge by an excavation operation such that an excavation angle between the calculated direction of the cutting edge of the bucket and the direction of movement of the cutting edge by the excavation operation keeps a predetermined angle, and causes the work vehicle to perform the excavation operation in the direction of movement.

  • Publication number: 20210040713
    Abstract: A system determines work executed by a work vehicle that includes a vehicle body and a work implement movably attached to the vehicle body. The system includes a camera attached to the vehicle body, and a processor. The camera is disposed to be oriented from the vehicle body toward a working position of the work implement, and generates image data indicative of images of the working position captured in a time sequence. The processor has a trained model in order to output a classification of the work corresponding to the image data. The image data serves as input data. The processor acquires the image data, and determines the classification of the work from the image data by image analysis using the trained model.

  • Publication number: 20210002871
    Abstract: A work implement's position is determined. Provided is a system including a work machine, the system comprising: a work machine body; a work implement attached to the work machine body; an imaging device that captures an image of the work implement; and a computer. The computer includes a trained position estimation model. The computer is programmed to obtain the image of the work implement captured by the imaging device and use the trained position estimation model to obtain a position of the work implement estimated from the captured image.

  • Publication number: 20200407952
    Abstract: There is provided a hydraulic excavator allowing a simple configuration to be employed to determine a posture of a work implement accurately. The work implement and an imaging device are attached to a revolving unit. The work implement operates on a prescribed operating plane. The imaging device captures an image of the work implement at an angle larger than 0° with respect to the operating plane. The controller determines a position of the work implement relative to the revolving unit based on a posture of the work implement in the image captured by the imaging device.

  • Publication number: 20190203443
    Abstract: A work vehicle includes a vehicular body, a work implement, and a controller. The work implement has a boom pivotable with respect to the vehicular body, a dipper stick pivotable with respect to the boom, and a bucket pivotable with respect to the dipper stick. The controller calculates a direction of a cutting edge of the bucket and determines a direction in which the cutting edge travels to the side of an open side of the bucket such that the calculated direction of the cutting edge of the bucket and the direction in which the cutting edge travels to the side on the open side of the bucket form an excavation angle of a predetermined angle, and the controller thus causes an operation of the work implement to be performed in the direction in which the cutting edge travels.

  • Publication number: 20190186100
    Abstract: A work vehicle includes a vehicular body, a work implement, a manipulation unit and a controller. The work implement has a boom pivotable with respect to the vehicular body, a dipper stick pivotable with respect to the boom, and a bucket pivotable with respect to the dipper stick. The manipulation unit is operated to output a manipulation command for the work implement. The controller controls the work implement in accordance with the manipulation command received from the manipulation unit. When in accordance with the manipulation command via the manipulation unit the bucket travels in a direction on the side of the back surface of the bucket with respect to the direction of the cutting edge of the bucket, the controller limits movement of the bucket in the direction in accordance with the manipulation command.

  • Publication number: 20180140804
    Abstract: A balloon catheter includes a balloon. The balloon allows restraint-free arrangement of an irregular region on the balloon for quickly inserting the balloon into a stenosis or stricture or an obstructed part while the balloon is in a contracted state, and allows for securely fixing the balloon within the stenosis or stricture or the obstructed part while the balloon is in an expanded state. The balloon can be easily produced, and can be folded without restraint (without requiring differentiation between the irregular region and the rest of the balloon). The balloon includes a base portion having an irregular region on its surface, and a coating agent coating the surface of the base portion. When the balloon is not expanded, the surface of the balloon is smooth and flat; and while the balloon is in an expanded state, the surface of the balloon is irregular.
