Abstract
A method for operating a self-driving working machine including determining an operating variable of a working device of the self-driving working machine and determining a longitudinal dynamics driving variable of the self-driving working machine. The method also includes checking whether a hazardous state for stability of the self-driving working machine can occur based on the determined operating variable and the determined longitudinal dynamics driving variable The method also includes intervening in longitudinal dynamics of the self-driving working machine depending on a check result based on the checking step.

A method for operating a self-driving working machine comprising:
- determining an operating variable of a working device of the self-driving working machine by determining that a task hydraulic request requested by an automatic system for automatically performing a task with the working device exceeds a predefined threshold communicated by the automatic system, wherein the operating variable includes a current operating state of the working device, and wherein determining the operating variable of the working device includes a query as to whether the automatic system is activated;
- determining a longitudinal dynamics driving variable of the self-driving working machine;
- checking whether a hazardous state for stability of the self-driving working machine can occur based on the determined operating variable and the determined longitudinal dynamics driving variable;
- and
- intervening in longitudinal dynamics of the self-driving working machine depending on a check result based on the checking step.
A controller for operating a self-driving working machine, the controller comprising:
- an evaluator for determining an operating variable of a working device of the self-driving working machine by determining that a task hydraulic requested by an automatic system for automatically performing a task with the working device exceeds a predefined threshold communicated by the automatic system and for determining a longitudinal dynamics driving variable of the self-driving working machine, wherein the operating variable includes current operating state of the working device, and wherein determining the operating variable of the working device includes a query as to whether the automatic system is activated;
- a checker for checking whether a hazardous state for stability of the self-driving working machine can arise based on the determined operating variable and the determined longitudinal dynamics driving variable,
- wherein the checker is set up to provide a check result based on the check;
- and
- an interface for outputting a control signal with which an intervention into longitudinal dynamics of the self-driving working machine can be carried out depending on a check result that can be provided by the checker.
