Abstract
A work vehicle includes a vehicular body and a work implement including a blade. The vehicular body includes a controller that controls an operation of the work implement and an acceleration sensor. The controller controls a blade propulsive angle θ of the blade based on an output from the acceleration sensor.
Claims14
A work vehicle comprising:
- a vehicular body;
- and
- a work implement including a blade, wherein
- the vehicular body includes a controller that controls an operation of the work implement and an acceleration sensor, and
- the controller obtains an acceleration on a horizontal plane from the acceleration sensor, determines a direction of travel of the work vehicle, and changes a blade propulsive angle of the blade by an amount equal to an amount of change in angle in the direction of travel based on the obtained acceleration from the acceleration sensor.
A work vehicle comprising:
- a swing circle;
- a blade supported on the swing circle;
- a front frame;
- a draw bar attached to the front frame to fluctuate, the swing circle being attached to the draw bar;
- an acceleration sensor provided in the draw bar;
- and
- a controller that obtains an acceleration on a horizontal plane from the acceleration sensor, determines a direction of travel of the work vehicle, and changes a blade propulsive angle of the blade by an amount equal to an amount of change in angle in the direction of travel by causing the swing circle to rotate based the obtained acceleration from the acceleration sensor.
A method of controlling a work vehicle, the work vehicle including a vehicular body and a work implement including a blade, the vehicular body including a controller that controls an operation of the work implement and an acceleration sensor, the method comprising:
- receiving, by the controller, a signal provided from the acceleration sensor;
- obtaining, by the controller, an acceleration on a horizontal plane based on the signal from the acceleration sensor;
- and
- determining, by the controller, a direction of travel of the work vehicle and changing a blade propulsive angle of the blade by an amount equal to an amount of change in angle in the direction of travel based on the obtained acceleration from the acceleration sensor.
A method of controlling a work vehicle, the work vehicle including a swing circle, a blade supported on the swing circle, a front frame, a draw bar attached to the front frame to fluctuate, the swing circle being attached to the draw bar, an acceleration sensor provided in the draw bar, and a controller, the method comprising:
- receiving, by the controller, a signal provided from the acceleration sensor;
- obtaining, by the controller, an acceleration on a horizontal plane based on the signal from the acceleration sensor;
- and
- determining by the controller, a direction of travel of the work vehicle and changing a blade propulsive angle of the blade by an amount equal to an amount of change in angle in the direction of travel by causing the swing circle to rotate based on the obtained acceleration from the acceleration sensor.
