1. A control system for a machine, comprising:
- at least one sensor configured to generate a signal indicative of an inclination of the machine; and
a controller in communication with the at least one sensor and configured to;
stop operation of the machine in response to the inclination signal indicating an excessive incline;
determine a travel path taken by the machine prior to receiving the inclination signal indicating the excessive incline; and
autonomously control the machine to backtrack through the travel path.

11. A method of reducing machine rollover risk, comprising:
-
detecting a machine inclination; determining a rollover risk value based on the machine inclination; stopping machine operation in response to the rollover risk value; determining a travel path of the machine prior to stopping the machine in response to the rollover risk; and autonomously reversing operation of the machine according to the tracked movement, until the rollover risk has reduced below a predetermined value. - View Dependent Claims (12, 13, 14, 15)

16. A machine, comprising:
-
a power source; a traction device driven by the power source to propel the machine; a sensor configured to detect machine inclination; and a controller in communication with the sensor and the traction device, the controller configured to; warn an operator of the machine when the detected inclination falls within a predetermined range; stop operation of the traction device in response to the detected inclination exceeding the predetermined range; determine a travel path taken by the machine prior to encountering an incline exceeding the predetermined threshold; and autonomously control the machine to backtrack through the travel path. - View Dependent Claims (17)

18. A method of monitoring machine rollover conditions, comprising:
-
detecting a machine inclination; determining a rollover risk value based on the machine inclination; determining changes in loading of the machine during travel of the machine, including continuously determining changes in a lateral or longitudinal location of a center of gravity of the machine; and continuously dynamically updating the rollover risk value based on the continuously determined changes in the lateral or longitudinal location of the center of gravity of the machine.

19. A method of monitoring machine rollover conditions, comprising:
-
detecting a machine inclination; determining a rollover risk value based on the machine inclination during travel of the machine; tracking a location of the machine; and generating a map based on the tracked location of the machine that includes indications of at least three levels of the rollover risk value for different tracked locations the machine has traversed. - View Dependent Claims (21, 22, 23, 24)

20. A method of reducing rollover risk of a machine having a braking system, a steering system, and at least one movable machine tool, the method comprising:
-
detecting a machine inclination; determining a rollover risk value based on the machine inclination during travel of the machine; and moving the machine tool in response to the detected machine inclination to reduce the rollover risk value. - View Dependent Claims (25, 26)
