Abstract
A method for simulating the movement behavior of a fluid in a closed moving container is provided. The simulation is based on the determination of the potential movement path of the center of gravity of the volume of the fluid as an elliptical trajectory situated in a disturbance plane having certain semi-axes.

A method for controlling a vehicle comprising a closed container with a fluid, the container having a capacity (VT) and the fluid having a volume (VL), the method comprising the steps:
- determining, using a simulation in a computing unit, a movement behavior of the fluid as a reaction to a planned movement change of the vehicle by determining, independent of a shape of the container, a potential movement path of a center of gravity of the volume (VL) of the fluid as an elliptical trajectory;
- determining expected trajectory data and forces of mass that will act on the container caused by the movement behavior of the fluid due to the planned movement change;
- transmitting the expected forces of mass to a control computer of the vehicle;
- and
- compensating, in real-time, for reactive effects on control of the vehicle induced by the expected forces of mass.
A method for dropping a load from vehicle, the load having a closed container with a fluid, the container having a capacity (VT) and the fluid having a volume (VL), the method comprising the steps:
- determining, using a simulation in a computing unit, a movement behavior of the fluid as a reaction to a drop of the load from the vehicle by determining, independent of a shape of the container, a potential movement path of a center of gravity of the volume (VL) of the fluid as an elliptical trajectory;
- determining expected trajectory data and forces of mass that will act on the container caused by movement of the fluid when dropping the load;
- transmitting the expected trajectory data and forces of mass to an on-board computer of the vehicle;
- determining, using the on-board computer and accounting for an actual trajectory data of the movement path of the vehicle, whether dropping the load is permissible and authorized;
- and
- dropping the load when it is determined that dropping is permissible and authorized.
A method for dropping a load from an vehicle, the load having a closed container with a fluid, the container having a capacity (VT) and the fluid having a volume (VL), the method comprising the steps:
- determining, using a simulation in a computing unit, a movement behavior of the fluid as a reaction to a drop of the load from the vehicle by determining, independent of a shape of the container, a potential movement path of a center of gravity of the volume (VL) of the fluid as an elliptical trajectory;
- determining expected trajectory data and forces of mass that will act on the container caused by movement of the fluid when dropping the load;
- transmitting the expected trajectory data and forces of mass an on-board computer of the vehicle;
- and
- generating, using the on-board computer, a suggested a movement procedure of the vehicle to allow a safe drop of the load;
- and
- executing the suggested movement procedure while dropping the load.
