Description

[0001] The invention relates to a method for generating a current operating strategy proposal for a motor vehicle. The invention also relates to a motor vehicle configured to implement a corresponding method.

[0002] For example, methods for suggesting a travel route are known. For example, it is known that a vehicle's navigation system can determine, based on the location of a driver's workplace, the time of day, and the day of the week, that the driver wishes to drive to the home address stored in the navigation system at the end of a working day. The navigation system can then immediately suggest the destination, i.e., the location of home, to the driver without the driver having to take any action themselves. The location of home can either be taught to the navigation device or navigation system, or the navigation system can learn this location by regularly driving to this location after work.

[0003] US 2010 / 0 075 655 A1 discloses a method for controlling vehicle functions using a mobile phone, whereby driver preferences can be entered via an interface on the mobile phone. DE 10 2012 023 109 A1 describes a method in which driver-specific user data is transmitted from a mobile phone to a motor vehicle via a wireless communication connection.

[0004] WO 02 / 034571 A2 describes a driver evaluation system based on operating data, driver activity data, and environmental data. US 2017 / 0158206 A1 discloses a method for supporting safe driving behavior, taking into account a vehicle state, a driver state, and environmental conditions.

[0005] US 2013 / 0 204 455 A1 discloses a method for transmitting driver settings from one vehicle to another via an external device. US 8 626 357 B1 discloses an access system for vehicles, wherein driver identification is provided via an ID code in a portable element.

[0006] DE 10 2012 108 934 A1 discloses a method for determining the range of an electric vehicle depending on a user group-specific mobility profile and depending on environmental conditions.

[0007] It is an object of the present invention to provide a method in which a motor vehicle can be operated more individually.

[0008] This problem is solved by a method according to the independent claim.

[0009] In a method according to the invention, a current operating strategy proposal is generated for a motor vehicle. The operating strategy proposal suggests to a user of the motor vehicle how the motor vehicle can be operated with respect to at least one resource available to the motor vehicle. The following steps are performed: (a) recording an individual characteristic of the user of the motor vehicle; b) selecting user-specific operating information describing how the user usually operates a motor vehicle, in particular a fictitious motor vehicle, based on the individual characteristic; c) determining a current operating requirement of the user for the motor vehicle based on the operating information; d) determining the resource currently available to at least one motor vehicle; e) comparing the operating requirement with the at least one resource; and f) generating the current operating strategy proposal based on the comparison, wherein the operating strategy proposal suggests to a user of the motor vehicle how the motor vehicle can be operated with respect to at least one resource available to the motor vehicle.

[0010] In particular, the method may further comprise: outputting the generated operating strategy proposal, in particular to the user, if the operating strategy proposal is accepted or if a commitment is required at all.

[0011] In particular, outputting the operating strategy proposal to at least one control unit in the motor vehicle and / or to at least one charging station and / or to a service for controlling the charging station and / or to a home energy management device of a building and / or to an energy service provider, in particular in order to know when the motor vehicle can probably be used as a storage device again.

[0012] For example, it can then be taken into account that the building will consume energy from the vehicle's energy storage system at night and / or the state of charge (SoC) the vehicle is expected to arrive at the building with and / or the state of charge the vehicle intends to use again. If the building has an acute energy demand, a decision can then be made whether the vehicle will depart later than originally planned in order to provide the building with the required energy.

[0013] Planning the charge level of the vehicle's battery or traction accumulator can also be accompanied by lifespan management, as the battery is not always unnecessarily charged to 100% and therefore lasts longer.

[0014] In particular, the vehicle's state of charge can also be adjusted depending on the next usage period. For example, it is not necessary to fully charge the battery, since the current usage period does not require 100% of the energy of a fully charged battery, and the combined usage period does not require 100% of the energy of the next. However, it may also be the case that, based on knowledge of the next usage period, it is already known that there is enough time left to recharge the battery.

[0015] The invention is based on the realization that each user of a motor vehicle regularly operates the motor vehicle differently and therefore has different operating requirements for the motor vehicle. The current operating requirement is determined by knowledge of the operating information, i.e., knowledge of how the user usually or regularly operates a motor vehicle, i.e., the motor vehicle or another motor vehicle, in particular a fictitious motor vehicle composed of several different motor vehicles.

[0016] Before renting a motor vehicle or even before purchasing it, it can be checked whether the motor vehicle is actually suitable for the potential user and which services would be appropriate, e.g. charging services, in particular fast charging capability or direct current charging capability, or which configuration of the motor vehicle would be appropriate, such as switching to an electric vehicle.

[0017] The operating information is available to the user and encompasses many possible operating modes of a motor vehicle by the user at different times of day and / or days of the week and / or weather conditions, while the operating requirement for the motor vehicle is available for the current situation. This means that the operating requirement arises particularly when the operating information is combined with, for example, a time of day. Thus, the information from the operating information is selected for the operating requirement that matches the current situation, for example, the ambient temperature, the time of day, the day of the week, the weather conditions, and / or the user's state of health.

[0018] The user can therefore carry their operating information with them at all times, for example in their mobile communications device, in particular their smartphone or smartwatch, and then select a motor vehicle, for example a rental vehicle, and determine the operating requirements for the motor vehicle based on their operating information. It is then preferably determined whether the motor vehicle is suitable for the user at all, i.e. whether it is designed to meet the operating requirement in its current state, or with which configuration the motor vehicle is designed to meet the operating requirement. This is communicated to the user of the motor vehicle by the generated operating strategy proposal or output to them. In particular, the operating strategy proposal can also be output to at least one control unit of the motor vehicle and / or to a charging infrastructure.

[0019] The traction battery or the vehicle's energy storage unit can also be prepared for the next or subsequent use before operation. For example, the traction battery can be prepared for the upcoming traction requirement and / or comfort requirements, e.g., pre-tempered and / or pre-charged.

[0020] The operating information also includes, for example, the use of services and / or a driving style of the user and / or a speed forecast for an expected route and / or energy required when driving and / or energy required for the use of the motor vehicle as an energy buffer, e.g. for a building or another motor vehicle.

[0021] During the comparison in step e), the difference between the operating requirement and the available resource is determined. If the operating requirement exceeds the available resource, the operating strategy proposal is generated either in such a way that the motor vehicle is discouraged or the restrictions necessary for the operation of the motor vehicle are pointed out in order to meet the operating requirement, for example, a specific travel time. If the operating requirement appears possible given the available resource, the operating strategy proposal is generated in such a way that the use of the motor vehicle is possible, preferably without restrictions.

[0022] The operational requirement and the resource also include, for example, booked services for charging stations (reservation, access, payment), backend-based services, vehicle-transferable services, provision of the vehicle as an energy storage device for the home and for service providers (when can the motor vehicle be used as an energy storage device, e.g. when is it not moved), V2D use (V2D - vehicle-to-device).

[0023] The operating strategy proposal can be used for the user, in particular a driver of the motor vehicle, and / or as a specification for a control unit of the motor vehicle.

[0024] Preferably, the individual feature is provided by a mobile transponder carried by the user and is detected by a receiver of a door-opening device of the motor vehicle, in particular in step a). The transponder can therefore be referred to as an electronic key, which preferably has a non-volatile memory. For example, user-specific operating information can be stored in the non-volatile memory. In particular, the transponder and the receiver are wirelessly coupled, at least temporarily. The door-opening device is also known as a so-called DHS (door handle sensor). The door-opening device is advantageous for detecting the individual feature, since the motor vehicle is usually unlocked or unlocked before it is used, and the individual feature can be detected almost simultaneously in this process.

[0025] Furthermore, it is preferably provided that steps a) to f) are performed before the user enters the motor vehicle. Performing the steps before entering the motor vehicle is advantageous because the user then has the option of selecting a different motor vehicle or additional motor vehicle before getting into the motor vehicle and may have already made personal adjustments to the motor vehicle, for example, the rearview mirror, seat, or steering wheel. The driver would then have to make these adjustments again for the additional motor vehicle.It is also advantageous to carry out steps a) to f) before boarding, since then a rental agreement for the motor vehicle may not yet have been concluded and the user, if the user's operating requirements cannot be met with the available resources, can simply leave the vehicle unused without having to worry about the rental agreement and possibly also a rental payment being reversed.

[0026] Furthermore, it is preferably provided that the user-specific operating information selected in particular in step b) is provided by a mobile communications terminal of the user and / or a server external to the motor vehicle. Thus, it may also be the case that the communications terminal has a memory, in particular a non-volatile memory, on which the user's operating information is stored. The communications terminal, in particular a smartphone, can then be coupled to the motor vehicle wirelessly, in particular via Bluetooth or NFC (Near Field Communication), in order to transmit the operating information to the motor vehicle or to transmit the resources of the motor vehicle to the mobile terminal and then carry out the further steps either in the motor vehicle or in the mobile communications terminal. However, it may also be the case that user-specific operating information is provided by the server external to the motor vehicle.For example, the motor vehicle can be wirelessly linked to the external server and retrieve the operating information stored on the server or send the available resources to the server so that the server executes the next steps. In this case, only the current operating strategy proposal is transmitted from the server to the user and / or the motor vehicle. However, the current operating strategy proposal can also be transmitted to an infrastructure, in particular charging infrastructure, and / or a building or house. Transmission to a building is particularly important for the purchase scenario, i.e., when the user, as a potential buyer of the motor vehicle, is to be informed through the operating strategy proposal whether the motor vehicle is suitable for them.

[0027] Preferably, it is provided that comfort temperature information, equipment information, usage information of an entertainment device of the motor vehicle, usage information of a mobile radio data connection of the motor vehicle, weekly rhythm information, daily rhythm information, weather influence information and / or willingness-to-pay information of the user is selected as the user-specific operating information, in particular in step b).

[0028] The comfort temperature information describes which temperature the user regularly prefers in the vehicle interior. Using the comfort temperature information, it can then be determined, for example, how great the difference is compared to the current outside temperature in the area surrounding the vehicle and thus how much energy, for example cooling energy or heating energy, is required to maintain the interior temperature of the vehicle as desired or as usual while the user is operating the vehicle. The comfort temperature information can also be presented as a temperature range, for example between 19°C and 22°C. For example, it can also be planned whether and to what extent the next and the next but one usage cycle of the vehicle should also be provided with comfort temperature information.

[0029] The equipment information describes the features of the motor vehicle. For example, it describes which driver assistance systems the motor vehicle has, in particular which safety systems the motor vehicle has, which navigation device the motor vehicle has, which communication device the motor vehicle has, how many seats the motor vehicle has, what level of suspension the motor vehicle has, and which functions of the motor vehicle are supported by an electronic actuator, such as electronic window lifts.

[0030] The usage information of the entertainment device describes how the user uses the motor vehicle's entertainment device. For example, there are users who consume media, particularly music, often and / or loudly and therefore consume more energy than, for example, a user who rarely uses the entertainment device. However, it may also be the case that the user wants to receive a specific radio or television station that cannot be provided as a resource. Even then, the user's operating requirement exceeds the available resource. In this case, the operating strategy suggestion is then issued such that, for example, the user can use the motor vehicle, but must expect or make do with restrictions regarding the use of the entertainment device.

[0031] The usage information of the mobile data connection describes how often and to what extent the user typically uses the vehicle's mobile data connection. For example, does the user download media, in particular music or films, or does the user regularly check their emails while the vehicle is in operation, or does the user regularly send large data packets via the mobile data connection. The usage information of the mobile data connection can also be used to describe, for example, whether the user requires a fast connection, i.e. a connection with fast response times, or a connection with a high bandwidth, i.e. high throughput. The weekly rhythm information specifies, for example, that the user works from Monday to Friday and has free time on Saturday and Sunday.If the user intends to operate the vehicle on a weekday, the operating requirements are different than if the user wants to operate the vehicle at the weekend. For example, the user drives more energy-efficiently at the weekend because they have more time and don't have to rush from appointment to appointment. Alternatively, it is of course also possible that the user consumes more energy on weekdays because they have important appointments, or that the user is generally more stressed than at the weekend. The daily rhythm information describes how the user operates the vehicle at different times of day, particularly at different times of day. For example, it is possible that the user operates the vehicle more energy-efficiently in the morning because they are still a little tired, but it is also possible that the driver uses particularly a lot of energy in the morning because they want to get to work quickly.For example, the driver's individual driving style or speed profile is also taken into account. An energy profile can also be considered, such as leaving the vehicle at home on a day when household appliances consume less energy, leaving more energy available for charging the vehicle—for example, on the weekend rather than on laundry day.

[0032] The weather influence information describes, in particular, how the user of the motor vehicle reacts to different weather situations and how they operate the vehicle differently depending on the weather conditions. For example, the user of the motor vehicle may operate the vehicle more slowly in rainy weather, thus using more energy than in sunny weather and on a dry road surface. However, the driver may also drive more slowly in the dark or at night, thus operating the vehicle with less energy than during the day.

[0033] The willingness-to-pay information describes how much money the user is prepared to spend on operating the motor vehicle. For example, the motor vehicle may be available as a rental vehicle and the user may only be willing to pay a certain amount to rent the vehicle. If the user is then only willing to pay a certain amount, the motor vehicle can, for example, be functionally restricted and the user can be offered the functionally restricted version of the motor vehicle for use. This restricted configuration is then given to the user, in particular via the operating strategy suggestion. The user can then decide whether the restricted configuration of the motor vehicle is sufficient or whether they would like to pay more for a more extensive configuration of the motor vehicle.less restricted configuration of the motor vehicle or whether he would like to look for another or additional motor vehicle and not rent the motor vehicle offered.

[0034] Furthermore, it is preferably provided that a current travel destination of the user is specified and the user's current operating requirement for the motor vehicle is determined based on the operating information and the current travel destination. For example, the user can specify their travel destination, particularly before starting the journey, and the operating requirement is then determined together with the travel destination and the operating information. This is advantageous because the operating information is based in particular on the user's usual actions or regular procedure and thus, for example, an action has to be carried out frequently for it to be taken into account in the operating information. For example, if the user wants to travel to a completely new travel destination, this cannot be suggested or predicted by the operating information.The destination, like the operating information, is then used to determine the user's operating requirements for the vehicle. The destination can also be guessed, for example, by recognizing movement patterns and / or start patterns and / or destination patterns.

[0035] Furthermore, it is preferably provided that, based on the current travel destination, an energy expenditure for reaching the travel destination, a weather condition between the travel destination and a current location of the motor vehicle, a road condition of a road between the travel destination and the location, a travel time from the location to the travel destination and / or travel route information from the location to the travel destination is determined, and the user's current operating requirement for the motor vehicle is determined based on the energy expenditure, the weather condition, the road condition, the travel time and / or the travel route information, in particular in step c). The energy expenditure can, for example, be in the form of electricity consumption or fuel consumption. The energy expenditure then also depends, for example, on the travel route, the gradient during the journey to the travel destination and the road condition.The user's current operating requirements for the vehicle are determined more precisely based on the energy consumption, weather conditions, road conditions, journey time and / or route information.

[0036] Furthermore, it is preferably provided that an energy reserve state of a traction energy storage device of the motor vehicle, an equipment state of the motor vehicle, a power capacity of a traction unit of the motor vehicle, and / or a mobile radio data transmission capacity of the motor vehicle is determined as the resource, in particular in step d). The energy reserve state describes, for example, the charge state of a battery configured as the traction energy storage device or the level of a fuel tank of the motor vehicle.

[0037] The energy reserve status describes how much energy the vehicle can currently provide without recharging and / or refueling. The equipment status describes, for example, which driver assistance systems are installed in the vehicle or which functions of the vehicle are supported or fully executed by electrical actuators.

[0038] The equipment status can indicate, for example, whether the motor vehicle has an infotainment system or entertainment device, a navigation device, adaptive cruise control, or a parking assistance device. The equipment status can also indicate the data storage capacity and / or energy storage capacity of the motor vehicle and / or the services the motor vehicle can offer.

[0039] The power capacity of the traction unit describes the maximum power that the traction unit can draw on when the motor vehicle is configured as intended. For example, the motor vehicle may be configured with a different power capacity depending on how much the user is willing to pay for the vehicle. For example, the user may only be willing to pay for a certain power capacity. In this case, the motor vehicle is preferably limited to the power capacity that the user is willing to pay. This limitation is preferably implemented through purely electronic intervention. For example, the user can then only use 50 kW instead of the possible 70 kW. For example, energy storage resources of the motor vehicle can also be enabled or disabled, for example in the case of a rental vehicle or.For leased vehicles, energy storage operation can be blocked or added for an additional charge.

[0040] The mobile data transmission capacity describes the speed and / or throughput at which data can be transmitted via the mobile network to or from the vehicle.

[0041] Furthermore, it is preferably provided that the current operating strategy proposal suggests at least one possible route, possible equipment of the motor vehicle, a possible capacity limitation of a traction unit of the motor vehicle and / or a necessary energy refill stop, in particular in step f). The possible route suggests to the user which route is possible according to the operating requirements. For example, there may be different routes to reach the destination. However, it may be that the user can only use some of the routes to the destination so that the resources are sufficient to meet the operating requirements. The possible route is then, for example, a route without a pleasant view or a route which, for example, is subject to a toll and is therefore more expensive than an alternative route that is not possible.

[0042] The possible equipment describes, for example, which equipment of the motor vehicle can be suggested to the driver so that they can operate the motor vehicle according to the operating requirements. For example, it may be that the user is not willing to pay enough money to be able to use more equipment than the suggested. However, it may also be the case that the resources, in particular energy, are not sufficient to use an air conditioning system in the motor vehicle as an equipment. The possible capacity restriction describes which capacity can be made available to the user so that the operating requirements are met. For example, if the user is only willing to spend a certain amount of money on renting the motor vehicle, the performance capacity of the traction unit may be restricted.

[0043] However, it may also be the case that the full power capacity of the motor vehicle is made available to the user so that they can, for example, drive up steep mountain passes without any problems. The necessary energy refill stop suggests to the user in particular that the destination cannot be reached with the currently available energy, but that an energy refill stop is necessary to charge the motor vehicle or to refuel the motor vehicle. Multiple energy refill stops may also be necessary. Preferably, the number of refill stops and / or the position and / or duration of the refill stops are suggested to the user. For example, it may be that charging a battery takes longer than refueling a motor vehicle's fuel tank.The motor vehicle can also be designed as a hybrid vehicle and have both an electric motor and an internal combustion engine as the traction unit.

[0044] Furthermore, it is preferably provided that the current operating strategy proposal proposes at least one additional motor vehicle that is different from the motor vehicle, in particular in step f), and that provides the at least one resource at least in accordance with the operating requirement. For example, it may be the case that the motor vehicle, in particular even if restricted, cannot meet the operating requirement with its currently available resources. The operating strategy proposal then suggests to the user, in particular, that they do not use the motor vehicle, but rather use the additional motor vehicle, since this can be operated in accordance with the operating requirement. The additional motor vehicle can then, for example, also be part of a rental car fleet.For example, when the current operating strategy proposal is issued, the user is in a large parking lot with rental vehicles and is advised against using the vehicle but is directed to the other vehicle, which is parked just a few vehicles away.

[0045] Preferably, the generated operating strategy proposal is output to a charging infrastructure facility external to the vehicle, which is designed to charge the motor vehicle. The charging infrastructure facility can be designed, for example, as a direct current charging station, particularly a private or public one, and / or an alternating current charging station. The operating strategy proposal can be output wirelessly, for example, particularly via a mobile data network.

[0046] Preferably, provision is made for determining the intermediate storage requirement for energy external to the vehicle in a traction energy storage device of the motor vehicle, and for determining the user's current operating requirement for the motor vehicle based on the operating information and the intermediate storage requirement. The energy external to the vehicle is provided, for example, by a private photovoltaic system or by an energy provider. Preferably, the energy is stored in the traction energy storage device of the motor vehicle when excess energy is being generated (for example, in the afternoon). The intermediate energy storage device or the traction energy storage device can then be discharged again when less energy is being generated than is currently being consumed (for example, in the evening).

[0047] Preferably, the resource is determined by the availability of a public charging facility for the motor vehicle. This makes it possible to determine whether the public charging facility can be reserved at the time of the expected arrival at the charging facility and thus whether it will be available upon arrival. For example, some charging facilities cannot be booked or reserved at all, and others may already be booked by the time of arrival.

[0048] Furthermore, the invention also relates to a motor vehicle which is designed to carry out a method according to the invention.

[0049] In particular, the motor vehicle is designed as an electric vehicle, preferably BEV (battery electric vehicle) or PHEV (plug-in hybrid electric vehicle), or also as a mild hybrid vehicle.

[0050] Advantageous embodiments of the method according to the invention are to be regarded as advantageous embodiments of the motor vehicle according to the invention.

[0051] Embodiments of the invention are explained in more detail below with reference to a schematic drawing.

[0052] The figure shows a schematic plan view of an embodiment of a motor vehicle according to the invention with a door opening device.

[0053] In the figure, identical or functionally identical elements are given the same reference symbols.

[0054] The figure shows a motor vehicle 1 in a schematic top view. A user 2 of the motor vehicle 1 is located next to the motor vehicle 1. According to the exemplary embodiment, the user 2 holds a mobile transponder 3 in their hand. The transponder 3 can also be located, for example, in a pocket of the user 2 or in a variety of other locations on or near the user 2.

[0055] The motor vehicle 1 has a door opening device 4. The door opening device 4 comprises a receiver 5, an evaluation unit 6, an antenna 7, and a proximity sensor 8. The proximity sensor 8 is arranged on a door handle 9 of the motor vehicle 1. According to an exemplary embodiment not shown in detail, the motor vehicle 1 can also be designed without the door handle 9. The proximity sensor 8 can then be arranged at a variety of positions on the motor vehicle 1, but preferably where the (non-existent) door handle 9 is usually positioned.

[0056] The proximity sensor 8 detects an approach, in particular of a hand of the user 2, to the door handle 9, and the evaluation unit 6 sends a wake-up signal via the antenna 7 to the transponder 3. The transponder 3 then exchanges information with the receiver 5. If the code of the transponder 3 matches a code in the evaluation unit 6, a door 10 of the motor vehicle 1 is unlocked. The door handle 9 is arranged on the door 10. According to the exemplary embodiment, the door 10 is designed as a driver's door. In particular, the door 10 is a front door, which is arranged on the steering wheel side of the motor vehicle 1. The door 10 can thus be arranged on a left side or a right side of the motor vehicle 1, depending on the design of the motor vehicle 1.

[0057] Transponder 3 provides an individual characteristic 11. Individual characteristic 11 can, for example, be stored as a unique sequence of numbers in transponder 3.

[0058] The figure also shows a mobile communications terminal 12 of user 2 and a server 13 external to the motor vehicle. The communications terminal 12 is preferably embodied as a smartphone. The server 13 is embodied, for example, as any data server that can provide data, in particular via an internet connection. User-specific operating information 14 is stored in the communications terminal 12 and / or the server 13. The user-specific operating information 14 describes how the user 2 normally operates the motor vehicle 1 or a variety of other vehicles, which can be summarized as a fictitious motor vehicle. The operating information 14 is therefore not limited to the motor vehicle 1, but can describe the usage behavior of the user 2 with regard to several different motor vehicles.The operating information 14 is therefore user-dependent and preferably different for different users and therefore individual.

[0059] The operating information 14 describes comfort temperature information, equipment information, usage information of an entertainment device 15 of the motor vehicle 1, usage information of a mobile data connection 16 of the motor vehicle 1, weekly rhythm information, daily rhythm information, weather influence information, and / or willingness-to-pay information of the user 2. The operating information 14 can also describe a booked service, an energy flow variable, a driving style or the resulting driving trajectory, a comfort requirement, in particular preheating and / or cooling, a most likely route, a pre-booking of an energy storage device of the motor vehicle 1, in particular as an intermediate storage device, by an energy provider, for example, and / or a freight load.

[0060] The entertainment device 15 is designed, for example, as an entertainment system, radio, television, or media player. The mobile radio data connection 16 is designed, for example, for data transmission from the motor vehicle 1 to a mobile radio transmission tower.

[0061] Based on the operating information 14, a current operating request 17 from the user 2 for the motor vehicle 1 is determined. The operating request 17 is determined, in particular, based on the operating information 14 and a current time of day and / or a current day. In particular, the part of the operating information 14 that matches the current time of day or the current time and day and / or, for example, the current season and / or the current weather conditions is selected for the operating request 17.

[0062] The operating requirement 17 then describes which exact requirements the user 2 currently has for the motor vehicle 1 in order to be able to put the motor vehicle 1 into operation as desired or expected.

[0063] According to the exemplary embodiment, it is also provided that the user 2 enters a current travel destination 18. The current travel destination 18 can, for example, be entered into a navigation device 19 of the motor vehicle 1. The navigation device 19 has, for example, map data and is preferably coupled to a global navigation satellite system.

[0064] By entering the travel destination 18, the current operating requirement 17 can be determined based on the current travel destination 18 in addition to the operating information 14.

[0065] The current travel destination 18 can also be used to determine an energy expenditure to reach the travel destination 18 and a weather condition between the travel destination 18 and a current location 20 of the motor vehicle 20. Furthermore, the current travel destination 18 can be used to determine the operating requirement 17 based on a road condition 21 of a road 22 between the travel destination 18 and the location 20. However, the current travel destination 18 can also be used to determine a travel time between the travel destination 18 and the location 20 and / or route information which describes which route, i.e. which roads are traveled from the location 20 to the travel destination 18.

[0066] Furthermore, an energy reserve state 23 of a traction energy storage device 24 of the motor vehicle 1 is determined as a resource of the motor vehicle 1. An equipment state 25 of the motor vehicle 1 is preferably also determined as the resource of the motor vehicle 1. The equipment state 25 describes, for example, which driver assistance devices the motor vehicle 1 has and / or which units of the motor vehicle 1 can be actuated by an electric actuator. The equipment state 25 describes, for example, whether the motor vehicle 1 has an air conditioning system or even automatic climate control and how it is heated, for example, how an air flow is directed, i.e. whether the air flow is directed towards the footwell or whether only radiant heat from an infrared radiator is used.Furthermore, a power capacity 26 of a traction unit 27 of the motor vehicle 1 is determined as the resource. The power capacity 26 indicates, for example, the maximum power, for example in kW, that the traction unit 27 can provide. However, a mobile data transmission capacity 28 is also determined as the resource. The mobile data transmission capacity 28 describes the speed at which a certain amount of data can be transmitted.

[0067] A comparison is performed between the operating requirement 17 and at least one of the resources 23, 25, 26, 28. Based on the comparison, a current operating strategy proposal 29 is generated. According to the exemplary embodiment, the operating strategy proposal 29 proposes a possible route, a possible configuration of the motor vehicle 1, a possible capacity limitation of the traction unit 27, and / or a necessary energy refill stop. The energy refill stop is, for example, a stop at a gas station for refueling and / or recharging electrical energy.

[0068] However, the operating strategy proposal 29 can also suggest to user 2 that motor vehicle 1 does not meet their operating requirement 17 and that another motor vehicle 30 is better suited to their operating requirement 17. The other motor vehicle 30 then preferably provides at least one resource sufficiently so that the operating requirement 17 of user 2 can be met at the current time.

[0069] The operating strategy proposal 29 can, for example, be output to the user 2 via the communication terminal 12. The operating strategy proposal 29 can, for example, also be generated in the communication terminal 12 or in the vehicle-external server or in the motor vehicle 1.

[0070] Motor vehicle 1 can, for example, be designed as an at least partially autonomously operable motor vehicle or a fully autonomously operable motor vehicle. The equipment state 25 of motor vehicle 1 can, for example, also include a traffic light prediction device or a traffic light prediction service.

[0071] Due to the presence of the operating information 14, when the user 2 starts using the motor vehicle 1, for example, a radio program or a podcast can be continued at the point at which the user 2 last stopped listening.

[0072] The resource can also include an air conditioning compressor of the motor vehicle 1. The operating strategy proposal 29 can then, for example, also output an optimized operating strategy for driving the air conditioning compressor.
