A method is disclosed for operating an underwater vehicle. According to the method, the pressure difference between a container which can be filled with water and/or gas, especially air, in order to alter the weight of the vehicle and the water pressure outside the vehicle, is regulated to a predeterminable set value. A suitable device for carrying out this method, includes a circuit for regulating pressure difference between the pressure inside the container an the water pressure outside the vehicle to a predeterminable set value.

What is claimed is: 1. A method for operating an underwater vehicle, comprising: detecting a pressure in a container, fillable with water and a gas for varying the vehicle weight; and regulating a pressure difference between the pressure in the container and outboard water pressure, wherein the pressure difference is regulated to a predeterminable set value for regulating a volume through-put of water between the outboard water and the container to a constant value. 2. The method as claimed in claim 1, further comprising: measuring an actual value of the pressure difference between the pressure in the container and the outboard water pressure. 3. The method as claimed in claim 2, wherein the measuring step includes subtracting the measured actual value of the pressure difference from the predetermined set value in order to obtain a measure of the system deviation. 4. The method as claimed in claim 1, wherein, in the course of the regulation for the pressure difference, at least one of a function proportional to the system deviation, its integral and a differential is formed as a regulating signal. 5. The method as claimed in claim 4, wherein, in order to improve the dynamics in the event of set value changes, the regulating signal is combined additively with a signal, derived from the set value, to form a dynamized regulating signal. 6. The method as claimed in claim 5, wherein the dynamized regulating signal is influenced by one or more signals. 7. The method as claimed in claim 6, wherein the dynamized regulating signal is modified by a filling level measured value for the container that can be filled for the purpose of varying the vehicle weight, in order to obtain a regulating signal corrected for filling level. 8. The method as claimed in claim 7, wherein the regulating signal, at least one of dynamized and corrected for filling level, is modified by a pressure signal for the outboard pressure, in order to obtain a regulating signal corrected for diving depth. 9. The method as claimed in claim 8, wherein the regulating signal, at least one of dynamized, corrected for filling and corrected for diving level, is bounded in order to correspond to further set values. 10. The method as claimed in claim 9, wherein the pressure difference regulating signal, at least one of dynamized, corrected for filling level, corrected for diving depth, and bounded, is used as set value for a lower-level regulation for the rate of change of the pressure difference. 11. The method as claimed in claim 10, further comprising: calculating the rate of change of the pressure difference actual value calculated by differentiation from the measured actual value of the pressure difference between the pressure in the relevant container and the outboard water pressure. 12. The method as claimed in claim 11, wherein, in order to obtain a measure of the system deviation of the lower-level regulation for the rate of change of the pressure difference, the rate of change of the pressure difference actual value is subtracted from the regulating signal, used as set value signal and modified of the higher-level regulation for the pressure difference between the pressure in the container and the outboard water pressure. 13. The method as claimed in claim 12, wherein, in order to improve the dynamics in the event of set value changes, the system deviation of the lower-level regulation for the rate of change of the pressure difference is combined additively with a signal derived from the pressure difference set value to form a dynamized system deviation signal. 14. The method as claimed in claim 13, wherein, in the course of the lower-level regulation for the rate of change in the pressure difference, a function proportional to the possibly dynamized system deviation, at least one of its integral and differential is formed as regulating signal for the rate of change in the pressure difference. 15. The method as claimed in claim 1, wherein the regulating signal is used to derive drive signals for a ventilation valve, arranged upstream of the container connection for a gaseous pressure medium, and for a bleed valve arranged downstream of the container connection for the pressure medium. 16. The method as claimed in claim 15, wherein the drive signals for the valves effect a continuous adjustment of the same. 17. The method as claimed in claim 16, wherein the current valve positions are detected. 18. The method as claimed in claim 17, wherein the drive signals for the valves are interlocked with the current valve position of the respective other valve. 19. The method as claimed in claim 18, wherein the drive signals for the valves are obtained from the regulating signal. 20. The method as claimed in claim 19, wherein in the course of a valve position regulation, the detected valve position value is subtracted from the regulating signal used as set value and modified by interlocking in order to obtain a measure of the system deviation. 21. The method as claimed in claim 20, wherein, in the course of the valve position regulation, a function proportional to at least one of the system deviation of the valve position, its integral and differential is formed as drive signal for the relevant valve. 22. The method as claimed in claim 1, wherein the gas is air. 23. The method as claimed in claim 2, wherein, in the course of the regulation for the pressure difference, at least one of a function proportional to the system deviation, its integral and a differential is formed as regulating a signal. 24. The method as claimed in claim 1, wherein, in the course of the regulation for the pressure difference, at least one of a function proportional to the system deviation, its integral and a differential is formed as regulating a signal. 25. The method as claimed in claim 9, wherein the regulating signal, at least one of dynamized, corrected for filling and corrected for diving level, is bounded in order to correspond to further set values regarding a noise requirement. 26. The method as claimed in claim 2, further comprising: calculating the rate of change of the pressure difference actual value calculated by differentiation from the measured actual value of the pressure difference between the pressure in the relevant container and the outboard water pressure. 27. The method as claimed in claim 15, wherein the regulating signal is for the rate of change in the pressure difference.
