DETAILED DESCRIPTION OF THE DRAWINGS

[0148] Elements of the same design or function are provided with the same reference symbols in all the figures.

[0149] FIG. 1 shows an exemplary embodiment for a system for controlling a fuel use process of at least one vehicle.

[0150] The system includes at least one first vehicle 10 and optionally at least one second vehicle 20. The first vehicle 10 and the second vehicle 20 have, for example, at least an internal combustion engine. In addition, the first or the second vehicle 10, 20 can have an electric drive. The first vehicle 10 has a first control device 12 and the second vehicle 20 has a second control device 22. The system optionally has mobile user apparatuses which can be used by a respective user of the first vehicle 10 or of the second vehicle 20 for adapting the fuel supply of the respective first vehicle 10 or of the respective second vehicle 20. The respective mobile user apparatus 14, 24 can include, for example, a Smartphone and/or tablet PC and/or a plug-in navigation apparatus.

[0151] The first control device 12 is designed, for example, to sense and/or determine values, which represent a first fuel supply process in the first vehicle 10, for at least one fuel use characteristic variable K.

[0152] In addition, the first control device 12 is designed, for example, to sense and/or determine values for at least one parameter P which represents at least one peripheral condition of the fuel use in the first vehicle 10 during the first fuel use process.

[0153] The first control device 12 is designed, for example, to store the values of the at least one fuel use characteristic variable K in assignment to the respectively associated values of the at least one parameter P and to supply them at a first data interface.

[0154] In addition, the first control device 12 is designed to adapt, in response to reception of a profile data record Rec supplied at a second data interface, as a function of the supplied profile data record Rec, at least one second fuel parameter F2 of a fuel which is used by the first vehicle 10 during a second fuel use process.

[0155] This can take place, in particular, in such a way that the control device determines, as a function of the profile data record Rec, control signals, which are transferred to a gas station device. The fuel is then output by the gas station device as a function of the transferred control signals.

[0156] In particular, the first control device 12 is designed also to adapt the at least one second fuel parameter F2 of the fuel as a function of at least one second parameter P2_1, P2_2 which represents a current or predicted peripheral condition of the second fuel use process.

[0157] The values of the at least one second parameter P2_1, P2_2 are determined, for example, as a function of at least one predefined route attribute of a route section which is traveled along or is to be traveled along and/or as a function of travel times of the first or second vehicle 10, 20. In particular, in this way an operating mode of the first vehicle 10 or of the second vehicle 20 can be adapted as a function of the at least one predefined route attribute of the route section which is traveled along or is to be traveled along and/or as a function of the travel times. For example, during the adaptation of the fuel use, it is possible to take into account whether the journey is during the day or at night. In addition, it is possible to take into account specific target values for noise load, CO2 emissions, fine-dust emissions, etc. on specific route sections. It is therefore also possible to take into account information about the environmental zones of specific route sections. For example, an environmental zone for the first vehicle 10 or of the second vehicle 20 can be determined and in response the portion of a specific fuel type which is suitable for the respective route sections can be determined. In particular, in this context the route sections with specific environmental zones 1, 2, 3, 4 can be determined from a navigation map and/or from the back end and/or by means of a road sign identifier, for example also with a camera. The optimized portions of the fuel types can subsequently be determined and/or the vehicle 10, 20 can correspondingly switch fuel types over as it travels along the route.

[0158] Alternatively or additionally, the values of the at least one second parameter P2_1, P2_2 can be determined as a function of, for example,

[0159] a driving statistic of the first vehicle 10, or of the second vehicle 20, and/or

[0160] a vehicle setting with respect to a drive mode of the first vehicle 10 or of the second vehicle 20, and/or

[0161] at least one previously calculated route for the first vehicle 10 or for the second vehicle 20, and/or

[0162] a predicted external temperature, and/or

[0163] current exhaust gas data of the first vehicle 10 or of the second vehicle 20, and/or

[0164] data of a knocking sensor of the internal combustion engine of the first vehicle 10 or of the second vehicle 20, and/or

[0165] calendar data of a user of the first vehicle 10 or of the second vehicle 20, and/or

[0166] driver settings of the first vehicle 10 or of the second vehicle 20, and

[0167] a use of the first vehicle 10 or of the second vehicle 20 for a specific purpose.

[0168] The driving statistic can include, for example, a route length statistic and/or speed statistic and/or an altitude profile statistic (mountainous/flat) and/or travel density statistic (urban/rural). The vehicle settings such as, for example, comfort, sporty, normal, can be determined on the basis of settings of a driving permission switch which is used at present and/or has been used in the past. The at least one previously calculated route can include a determined most probable route of the first vehicle 10 or of the second vehicle 20. The current exhaust gas data can be determined, for example, by means of a closed-loop controlled catalytic converter of the first or second vehicle 10, 20. The driver settings can also include direct user settings and current user requirements. The use for the specific purpose may be, for example, a deployment of a rescue service.

[0169] For the determination of the values of the at least one second parameter P2_1, P2_2, for example, the mobile user apparatus 14, 24 can be configured to retrieve the corresponding data from the first vehicle 10 or the second vehicle 20, for example from a predefined software application (also referred to as an app), from specially administered data records or from the Internet via a wireless interface and to predefine the data correspondingly and combine it with special or specific scientific relationships. In this context, for example optimum values for the outputting of fuel can be displayed, read out and/or transferred directly or indirectly to the gas station for a fuel supply process. In the case of rental vehicles, it is also preferably possible to take into account calendar data or plans of one or more subsequent users and/or data of the following user or users in the ways described above.

[0170] A first mobile user apparatus 14 which is used by a respective user of the first vehicle 10 to adapt the fuel use of the first vehicle 10 is designed, for example, to receive the values of the at least one fuel use characteristic variable K which are supplied at the first interface and to determine a mathematical relationship between at least one supplied value, or a plurality of supplied values, of the at least one fuel use characteristic variable and the associated values of the parameters P and supply it as a data record and/or learning data. In addition, the first mobile user apparatus 14 is configured, for example, to supply the profile data record Rec at a predefined second interface.

[0171] The second control device 22 of the second vehicle 20 is configured, for example, to receive the profile data record Rec which is supplied at the second data interface, from the first mobile user apparatus 14, and to adapt, as a function of the supplied profile data record Rec, the at least one second fuel parameter F2 of the fuel which is used by the second vehicle 20 during a second fuel use process. This can take place, in particular, in such a way that the control device determines, as a function of the profile data record Rec, control signals which are transferred to the gas station device. The fuel is then output by the gas station device to the second vehicle 20 as a function of the transferred control signals.

[0172] Alternatively or additionally, the respective first mobile user apparatus 14 or the respective second mobile user apparatus 24 can be designed to adapt, as a function of the profile data record Rec and the values of the at least one second parameter P2_1, P2_2, the at least one second fuel parameter of the fuel which is used by the first vehicle 10 or the second vehicle 20 during a second fuel use process. This can take place, in particular, in such a way that the respective mobile user apparatus respectively determines, as a function of the profile data record Rec, control signals which are transferred to a gas station device. The fuel is then output by the gas station device to the first vehicle 10 or second vehicle 20 as a function of the transferred control signals.

[0173] The apportioning, as described above, of the functions of the first control device 12, second control device 22, the first mobile user apparatus 14 and the second mobile user apparatus 24 is exemplary and can also take place another way. Further variants are, for example, that the profile data record Rec is determined with means of the first vehicle 10, in particular also as a function of the data of the first mobile user apparatus 14, and the profile data record Rec or information dependent thereon is transferred to a fixed memory unit or computing unit, for example a Cloud, a back end or Internet portal or directly to the second mobile user apparatus 24 of the second user or directly or indirectly to a computing unit of the second vehicle 20.

[0174] FIG. 2 shows an exemplary flowchart of a program for adapting a fuel supply of at least one vehicle for the first mobile user apparatus 14.

[0175] The program is started in a step S1.

[0176] In a step S3, values of at least one predefined fuel use characteristic variable K, preferably of a plurality thereof, representing fuel use in a first vehicle 10, are read in. Respectively associated values of at least one parameter P, preferably a plurality thereof, are read in and/or stored in assignment to the values of the fuel use characteristic variables. The parameters P represent a peripheral condition or condition of a first fuel use process. The peripheral condition or condition relates, for example, to the first vehicle 10 and/or the internal combustion engine and/or the surroundings of the first vehicle 10.

[0177] Furthermore, the first control device 12 is designed, for example, to sense and/or determine values of at least one first fuel parameter F1 which represents a fuel which is used during the first fuel supply process in the first vehicle 10.

[0178] In addition to the values of the fuel use characteristics variables, the respectively associated values of at least one predefined first fuel parameter F1, preferably a plurality thereof, are then read in and/or stored. The fuel parameter F1 or fuel parameters F1 represent a fuel which is used during the first fuel use process in the first vehicle 10.

[0179] The respective fuel use characteristic variables K are supplied, for example, by the first control unit 12 of the first vehicle 10.

[0180] The at least one fuel use characteristic variable K is representative, for example, of at least one exhaust gas characteristic variable and/or one torque characteristic curve which is actually reached and/or of at least one detection variable of a knocking sensor of the internal combustion engine of the first vehicle 10 and/or of one or more ignition angles and/or ignition times.

[0181] The exhaust gas characteristic variable can include data from a closed-loop controlled catalytic converter of the first vehicle 10 and/or the data of the closed-loop controlled catalytic converter in combination with further data of the first vehicle 10 or of the first mobile user apparatus 14. In particular, the at least one exhaust gas characteristic variable is suitable for describing properties of the exhaust gas of the first vehicle 10. The torque characteristic curve which is actually obtained can be dependent on feeding-in of fuel, in particular with respect to different operating modes of the drive system of the first vehicle 10. The torque characteristic curve is preferably stored in assignment to these parameters P.

[0182] These fuel use characteristic variables K can preferably be sensed with means within the first vehicle 10 and/or determined from the data acquired with means of the first vehicle 10, for example with a computing unit of the first vehicle 10 or with the first mobile user apparatus 14, for example via an interface, similar to an on-board diagnostics interface. The determined fuel use characteristic variables K can be, expressed in scientific terms, sequences or time functions as well as relationships, expressed scientifically, for example, as formulas or formula coefficients, between two or more characteristic variables or one or more characteristic variables and as a function of one or more parameters P which each represent a condition of the fuel use or peripheral condition of the fuel use. Statistical data and/or dependency data and/or correlation data can also be collected, read out and used as the data for the knock sensor, ignition angle or ignition times. For example, the so-called OBD (On-Board Diagnostics) interface is also suitable for this.

[0183] The values of the parameters P can be supplied, for example, by the first vehicle 10 by means of the navigation device and/or the first control device 12 and/or the on-board computer of the first vehicle 10. Alternatively or additionally, the values of the parameters P can be supplied, for example, by second vehicle-external devices, for example a back end of the vehicle manufacturer. Alternatively or additionally, the values of the parameters P can be supplied by the mobile user apparatus itself

[0184] The value or values of the at least one first fuel parameter F1 can each be determined according to a refueling process. The at least one first fuel parameter F1 can be representative of proportions of various fuel types and/or of a mixing ratio of predefined fuel components in the respectively currently used fuel of the vehicle.

[0185] The value of at least one first fuel parameter F1 can comprise a fuel type and/or octane number and/or a viscosity and/or a proportion of a fuel component and so on.

[0186] The current composition of the fuel in the fuel tank of the vehicle can be determined in such a way that the mixing ratio, for example, of a Super fuel and an E10 gasoline, in the fuel tank is determined. The mixing ratio is preferably determined without sensors which are required for chemically analyzing the fuel. The current mixing ratio is preferably determined as a function of refueling data and/or billing data, stored in a vehicle computer and/or Smartphone and/or in a payment system for one or more last refueling processes. It is therefore possible, for example, to determine, for example, tables mathematically on the basis of stored predefined relationships in the Smartphone.

[0187] In a step S5, a mathematical relationship is determined between at least one supplied value, or a plurality of supplied values, of the at least one fuel use characteristic variable and the corresponding values of the at least one parameter P. In addition, in the step S5, the profile data record Rec comprising a data record and/or learning data is supplied on the basis of the at least one determined mathematical relationship.

[0188] The mathematical relationship is determined as a function of at least some of the stored or supplied values of the at least one fuel use characteristic variable K and the associated values thereof.

[0189] In particular, coefficients are determined for the profile data record on the basis of a predefined mathematical relationship which represents, for example, predefined equations, polynomials or simulations.

[0190] The profile data record Rec can represent, for example, at least one change in the fuel use characteristic variable K as a function of an adaptation of the at least one second fuel parameter F2.

[0191] The profile data record Rec can represent, for example, one or more adaptation variants of the at least one second fuel parameter F2, which variant or variants gives/give rise to optimization of the fuel use characteristic variable K.

[0192] The profile data record Rec can also represent just one difference, in particular an optimizing change, for example for carrying out a specific optimization step. As a result, this data which is intended for exchange can be configured extremely compactly and/or in a fashion which is absolutely noncritical for data protection.

[0193] Therefore, the data which is available in the first mobile user apparatus 14 can also be used, or data which the first mobile user apparatus 14 can determine or request in a wireless fashion from a further vehicle-external device, for example back end, Cloud, customer portal, etc.

[0194] The data which is read in from the first vehicle 10 or determined in the first vehicle 10 and which is read out with the first mobile user apparatus 14, for example the Smartphone of the user, for example via the on-board diagnostic interface or WLAN etc. can be used together with further data to determine the profile data record Rec with application software and then distribute the profile data record Rec if appropriate. The profile data record Rec and, in particular, the learning data are determined together with the parameters P of the fuel use which characterize the peripheral conditions which can be also at least partially sensed with the first mobile user apparatus 14 and/or conditioned by the first mobile user apparatus 14.

[0195] A resulting profile data record Rec_res can optionally be determined in the step S5 in that a resulting profile data record Rec_res is determined as a function of a plurality of profile data records which have been determined and supplied by respective first vehicles 10.

[0196] The profile data record Rec can be fused and/or aggregated with earlier profile data records of this type, for example by means of a software application and/or transferred by means of a customer portal, Cloud or back end. Subsequently, the profile data records of the first vehicles 10 can be used by other users or vehicles.

[0197] In this case, the first vehicles 10 are preferably each of the same type or related type. The respective profile data records may have been determined here taking into account identical or different peripheral conditions. This has the advantage that the profile data records can be much more precise and comprehensive. The learning data which has been determined in the first vehicle 10 under different peripheral conditions over a large number of fuel use phases can also be aggregated with one another, for example combined with a specific objective.

[0198] In a step S7, for example the at least one second fuel parameter is adapted as a function of the profile data record Rec and/or the resulting profile data record Rec_res. Alternatively or additionally, optimum operating parameters can also be determined for the drive system of the respective vehicle and/or optimum apportioning of energy types for the internal combustion engine and/or the electric drive can be determined.

[0199] In particular, in the step S7, at least one optimum fuel parameter F_opt can be determined. For example, it is possible to provide that a user predefines a selection and/or weighting of optimization criteria for the fuel use by means of a predefined operator control device of the first vehicle 10 and/or of the first mobile user apparatus 14.

[0200] Two or more options and relationships between the options can be displayed for simple predefining of the optimization criteria. At least two mutually influencing options can preferably be represented by means of a selection slider and/or spider diagram and/or a two-dimensional or three-dimensional selection space for selecting the optimization criteria. In this context, the optimization criteria can be positive, representing a value for a use which has been achieved or can be achieved, for example achieving maximum values, and/or negative, representing values for avoidance or reduction which has taken place or is possible (for example reduction of consumption, price, reduction of CO2 emissions and reduction of costs, and so on).

[0201] Alternatively or additionally, a set of possible changes of setting for the adaptation of the at least one second fuel parameter F2 can be determined as a function of the profile data record Rec, and the at least one second fuel parameter can then be determined as a function of a further predefined selection of the changes of setting.

[0202] At least one optimum fuel parameter F_opt and/or control signals which represent the at least one second fuel parameter can be determined as a function of the selected changes of setting and/or optimization criteria, and passed on to the gas station device, with the result that the gas station device can supply the correct quantities and fuel types.

[0203] For the optimization, it is also possible to take into account current or predicted peripheral conditions by virtue of the fact that the optimization also takes place as a function of the at least one second parameter P2_1.

[0204] FIG. 3 shows an exemplary block diagram of the program for adapting a fuel supply of the first vehicle 10 or of the second vehicle 20.

[0205] The profile data record Rec is determined, for example, as a function of first fuel parameters F1, parameters P, which represent peripheral conditions of the fuel use, and the fuel use characteristic variables K.

[0206] The first vehicle 10 can use, for example, different fuel types, for example E10, Super95 and/or premium fuels, wherein the fuel types each comprise a plurality of different fuel components. The first vehicle 10 can optionally use, for example, various special additives for example additive agents. In order to characterize the respective fuel which is currently used in the first vehicle 10, values of at least one first fuel parameter F1 are determined and/or supplied. The at least one first fuel parameter F1 can include, for example, an octane number. The first fuel parameters F1 can, for example, be calculated mathematically from portions of types.

[0207] The values of the parameters P of the fuel use can be determined, for example, from navigation data and/or from weather data and/or calendar data. The values of the parameters P can be determined and supplied, for example, by the mobile user apparatus of the vehicle user and/or by a back end server.

[0208] The fuel use characteristic variables K can be determined from the vehicle service data and/or workshop data and/or from the vehicle electrical system.

[0209] The profile data record Rec includes, for example, relationships between fuel types, characteristic curves and/or parameter groups of useful effects and damaging effects with respect to the current vehicle. Alternatively or additionally, the profile data record Rec includes the learning data.

[0210] The at least one second fuel parameter F2 of the fuel which is used by the first vehicle 10 or by the second vehicle 20 during a second fuel use process is adapted as a function of the profile data record Rec. In particular, the second fuel parameter is adapted in such a way that an optimized and/or preferred fuel type or fuel mixture is obtained.

[0211] The determination of the optimized or preferred fuel can optionally take place as a function of predefinition of optimization priorities by the respective vehicle user.

[0212] In each case, for example at a gas station, a desired quantity of one or more fuel types which are supplied by the gas station can be pre-ordered and/or called as a function of the determined adaptation of the at least one second fuel parameter.
