Abstract
A machine is disclosed. The machine may include a control system that includes a controller configured to: determine a center of gravity of the machine based on a state of the machine; determine at least one of a slope limit or a pitch limit for the machine based on the center of gravity; receive a command to perform an operation that, if performed, would affect at least one of a slope or a pitch of the machine; determine whether the operation, if performed, would cause the machine to exceed the at least one of the slope limit or the pitch limit; and selectively perform the operation based on determining whether the operation, if performed, would cause the machine to exceed the at least one of the slope limit or the pitch limit.
Claims20
A method, comprising:
- determining, by a controller of a machine, a center of gravity of the machine based on at least one of:
- an amount of swing of a conveyor of the machine,
- a height of a rotor of the machine, or
- a fluid level of a fluid tank of the machine;
- determining, by the controller, at least one of a slope limit or a pitch limit for the machine based on the center of gravity;
- receiving, by the controller, a command to perform an operation that, if performed, would affect at least one of a slope or a pitch of the machine;
- determining, by the controller, whether the operation, if performed, would cause the machine to exceed the at least one of the slope limit or the pitch limit;
- and
- selectively performing, by the controller, the operation based on determining whether the operation, if performed, would cause the machine to exceed the at least one of the slope limit or the pitch limit.
