Abstract
A motor grader includes a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle. A control method performed in the motor grader includes obtaining current topography in front of the motor grader and adjusting the blade angle to an angle in accordance with the current topography by revolving the swing circle.

A method of controlling a motor grader, the motor grader including a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle, the method comprising:
- obtaining current topography in front of the motor grader;
- determining whether the obtained current topography includes a recess;
- and
- adjusting the blade angle of the blade to an angle in accordance with the current topography by revolving the swing circle, wherein in the adjusting the blade angle, when the current topography is determined as including the recess, the swing circle is caused to revolve such that the blade angle is larger than the blade angle set by an operator of the motor grader.
A method of controlling a motor grader, the motor grader including a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle, the method comprising:
- obtaining current topography in front of the motor grader;
- determining whether the obtained current topography includes a projection;
- and
- adjusting the blade angle of the blade to an angle in accordance with the current topography by revolving the swing circle, wherein in the adjusting the blade angle, when the current topography is determined as including the projection, the swing circle is caused to revolve such that the blade angle is smaller than the blade angle set by an operator of the motor grader.
A method of controlling a motor grader, the motor grader including a blade between a front wheel and a rear wheel, the blade being attached to a swing circle which adjusts a blade angle, the method comprising:
- obtaining current topography in front of the motor grader;
- obtaining, from an image pick-up apparatus arranged in front of the blade, an amount of soil on a front surface of the blade;
- and
- adjusting the blade angle of the blade to an angle in accordance with the current topography and the amount of soil by revolving the swing circle.
A motor grader comprising:
- a swing circle configured to adjust a blade angle;
- a front wheel;
- a rear wheel;
- a blade attached to the swing circle, the blade being provided between the front wheel and the rear wheel;
- a sensor arranged in front of the blade and configured to obtain current topography in front of the motor grader;
- and
- a controller configured to control revolution of the swing circle, the controller being configured to adjust the blade angle of the blade to an angle in accordance with the current topography by having the swing circle revolve, wherein the controller is configured to:
- determine whether the obtained current topography includes a recess, and
- when the current topography is determined as including the recess, have the swing circle revolve such that the blade angle is larger than the blade angle set by an operator of the motor grader.
A motor grader comprising:
- a swing circle configured to adjust a blade angle;
- a front wheel;
- a rear wheel;
- a blade attached to the swing circle, the blade being provided between the front wheel and the rear wheel;
- a sensor arranged in front of the blade and configured to obtain current topography in front of the motor grader;
- and
- a controller configured to control revolution of the swing circle, the controller being configured to adjust the blade angle of the blade to an angle in accordance with the current topography by having the swing circle revolve, wherein the controller is configured to:
- determine whether the obtained current topography includes a projection, and
- when the current topography is determined as including the projection, have the swing circle revolve such that the blade angle is smaller than the blade angle set by an operator of the motor grader.
A motor grader comprising:
- a swing circle configured to adjust a blade angle;
- a front wheel;
- a rear wheel;
- a blade attached to the swing circle, the blade being provided between the front wheel and the rear wheel;
- a sensor configured to obtain current topography in front of the motor grader;
- an image pick-up apparatus arranged in front of the blade and configured to obtain an amount of soil on a front surface of the blade;
- and
- a controller configured to control revolution of the swing circle,
- the controller being configured to adjust the blade angle of the blade to an angle in accordance with the current topography and the amount of soil by having the swing circle revolve.
