Abstract
A work vehicle includes a vehicle body, running gear to cause the vehicle body to travel, a height adjuster to change a height of a center of gravity of the vehicle body, and a controller configured or programmed to, in accordance with at least one of a turning radius and an angular velocity of the vehicle body during a turn, control the height adjuster to maintain or lower the height of the center of gravity.
Claims9
A work vehicle comprising:
- a vehicle body;
- running gear to cause the vehicle body to travel;
- a linkage via which an implement is linked to the vehicle body;
- a height adjuster to change a height of a center of gravity of the vehicle body;
- and
- a controller configured or programmed to, in accordance with at least one of a turning radius and an angular velocity of the vehicle body during a turn, control the height adjuster to maintain or lower the height of the center of gravity;
- wherein
- the controller is configured or programmed to:
- control the height adjuster to lower the center of gravity when a state of a small turn where the turning radius is smaller than a reference radius is entered during a turn, and if the height of the center of gravity is higher than a reference height;
- change at least one of an amount of lowering the center of gravity and the reference height, in accordance with at least one of the turning radius, the angular velocity, and a weight of the work vehicle;
- and
- change at least one of the amount of lowering the center of gravity, the reference height, and the reference radius, in accordance with a type of the implement or a presence or an absence of the implement.
A controller to control a work vehicle including a vehicle body, running gear to cause the vehicle body to travel, a linkage via which an implement is linked to the vehicle body, and a height adjuster to change a height of a center of gravity of the vehicle body, the controller comprising:
- one or more processors;
- and
- one or more memories storing a computer program to be executed by the one or more processors;
- wherein
- the one or more processors is configured or programmed to:
- acquire, during a turn, information concerning at least one of a turning radius and an angular velocity of the vehicle body;
- control the height adjuster to maintain or lower the height of the center of gravity in accordance with the information;
- control the height adjuster to lower the center of gravity when a state of a small turn where the turning radius is smaller than a reference radius is entered during a turn, and if the height of the center of gravity is higher than a reference height;
- and
- change at least one of an amount of lowering the center of gravity and the reference height, in accordance with at least one of the turning radius, the angular velocity, and a weight of the work vehicle;
- and
- change at least one of the amount of lowering the center of gravity, the reference height, and the reference radius, in accordance with a type of the implement or a presence or an absence of the implement.
