  • Systems and methods for controlling machine ground pressure and tipping
    Patent number: 11242669
    Abstract: Methods and systems for operating an industrial machine. One system includes a controller that includes an electronic processor. The electronic processor is configured to calculate an eccentricity of a center of gravity of the industrial machine with respect to a center of a bearing propelling the industrial machine and calculate a ground pressure associated with the bearing based on the eccentricity of the center of gravity. The electronic processor is also configured to set a maximum torque applied by an actuator included in the industrial machine to a value less than an available maximum torque based on the eccentricity of the center of gravity and the ground pressure.
    Type: Grant
