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.

Self-propelled construction machine and method for controlling a self-propelled construction machine
11029704 · 2021-06-08 · ·

A construction machine system comprises a self-propelled construction machine and a total station. The construction machine possesses a machine frame, a drive means and a working means for altering the terrain. A position-determination means determines the position of a reference point on the machine in a first coordinate system independent of the machine. The position-determination means receives satellite signals from a global navigation satellite system (GNSS), wherein in normal operation the machine is controlled using the GNSS such that a reference point on the machine moves along a set target travel path. In a total station control mode, the machine is controlled without the GNSS and only using the total station based on a position of the standpoint and orientation of the total station ascertained in the GNSS control mode, and the position-determination of the construction machine occurs in a second coordinate system based on the total station.
