A control unit for controlling the supply of a vehicle having at least one internal combustion engine with multiple fuels has at least one input means for supplying optimization parameters, fuel parameters, and operational data, at least one storage unit for storing the optimization parameters, the fuel parameters, and the operational data, and at least one computing unit. The control unit is adapted for being connected to at least one first supply apparatus for supplying a first fuel to the internal combustion engine and to at least one second supply apparatus for supplying a second fuel to the internal combustion engine, and of controlling a first mass flow of supplied first fuel and a second mass flow of supplied second fuel. The computing unit optimizes the ratio of first mass flow and second mass flow for all operational phases of the vehicle to fulfill the specified optimization parameters.

1. A control unit for controlling the supply of a vehicle having at least one internal combustion engine with multiple fuels, comprising: at least one input means for supplying optimization parameters, fuel parameters, and operational data having data of operational phases of a mission to be performed by the vehicle;at least one storage unit for storing the optimization parameters, the fuel parameters, and the operational data; andat least one computing unit;wherein the at least one control unit is adapted:for being connected to at least one first supply apparatus for supplying a first fuel to the at least one internal combustion engine and to at least one second supply apparatus for supplying a second fuel to the at least one internal combustion engine;for controlling a first mass flow of the supplied first fuel and a second mass flow of the supplied second fuel; andfor using the at least one computing unit, establishing a ratio of first mass flow and second mass flow for one or more operational phases of the vehicle to fulfill the optimization parameters in consideration of the fuel parameters, storing the optimization parameters in the storage unit, and implementing the optimization parameters during the performance of the operational phases by controlling the first mass flow and the second mass flow. 2. The control unit of claim 1, wherein the optimization parameters are set to maximize a range of a mission to be covered by the vehicle. 3. The control unit of claim 1, wherein the optimization parameters are set to minimize fuel consumption. 4. The control unit of claim 1, wherein the optimization parameters are set to minimize climate-damaging effects of emissions. 5. The control unit of claim 1, which is adapted for displaying ascertained ratios of first mass flow to second mass flow for at least one operational phase of the vehicle via a display unit connected to the control unit. 6. An aircraft comprising: at least one power plant;at least one first fuel tank for carrying along a first fuel;at least one second fuel tank for carrying along a second fuel;a first supply apparatus;a second supply apparatus; anda control unit for controlling a supply of the at least one power plant with a first fuel and a second fuel according to claim 1. 7. A method for regulating the supply of at least one internal combustion engine of a vehicle with multiple fuels, comprising: providing optimization parameters, fuel parameters, and operational data having data of operational phases of a mission to be performed by the vehicle;ascertaining in each case a required first mass flow for a first fuel and a required second mass flow of a second fuel for an operational phase;ascertaining in each case the final mass of the vehicle after ending the operational phase using the first mass flow or the second mass flow;ascertaining in each case a specific fuel consumption upon use of the first fuel or the second fuel;scaling and comparing the specific fuel consumptions;selecting a suitable fuel having suitable predetermined fuel consumption; andsupplying the selected fuel to the internal combustion engine. 8. The method of claim 7, further comprising: (a) ascertaining a required first mass flow and a second mass flow at a first mixing ratio;(b) ascertaining a resulting final mass of the vehicle;(c) calculating the specific fuel consumption; and(d) changing the first mixing ratio and performing steps (a)-(d) again to optimize the specific fuel consumption according to the optimization parameters. 9. The method of claim 8, further comprising: iteratively performing the calculation step for a plurality of operational phases of the vehicle. 10. The method according to claim 7, further comprising: activating a display unit. 11. The method according to claim 7, wherein the method is performed again once or multiple times after beginning the mission. 12. The method according to claim 7, wherein the step of ascertaining the required first mass flow and the required second mass flow is performed in consideration of a maximization of a range of the mission to be covered by the vehicle. 13. The method according to claim 7, wherein the step of ascertaining the required first mass flow and the required second mass flow is performed in consideration of a minimization of the fuel consumption. 14. The method according to claim 7, wherein the step of ascertaining the required first mass flow and the required second mass flow is performed in consideration of a minimization of climate-damaging effects of emissions.
