Abstract
The invention relates to a method of operating a mobile work machine with a ground pressure limitation and to a corresponding work machine. A maximum permitted ground pressure is compared with an actually present ground pressure.
Claims15
A method of operating a mobile work machine with a ground pressure limitation, comprising the steps:
- detecting a current unit load of the mobile work machine via sensors;
- determining a maximum permitted ground pressure;
- calculating an actual ground pressure based on the current unit load;
- comparing the calculated actual ground pressure with the maximum permitted ground pressure;
- and
- reporting the comparison result to an operator of the mobile work machine via a visualization and/or stopping a movement of the mobile work machine that increases the ground pressure on an exceeding a limit value of the actual ground pressure.
