Description

The invention relates to a method for operating a motor vehicle, in particular a motor vehicle, according to the preamble of claim 1.Such a method for operating a motor vehicle, in particular a motor vehicle such as a passenger car, is already known from US 2016 / 0244029 A1, for example. In the method, the rolling capability thereof is set by means of an electronic computing device of the motor vehicle. The rollability is to be understood in particular as meaning that the motor vehicle is in a state in which the motor vehicle can be rolled, that is to say rolled, for example along a floor, for example by means of an external force or force acting on the motor vehicle from the outside, by setting the rollability or when the rollability is set. Such an external force is exerted on the motor vehicle, for example, by a conveying device, in particular a wash line, or by a person who, for example, pushes the motor vehicle. By adjusting the rollability, the motor vehicle can be conveyed through the wash line, for example by means of the conveying device, without the motor vehicle itself being driven.Furthermore, DE 10 2015 201 981 A1 discloses a method for safely towing a vehicle. In the case of such towing of a vehicle, the adjustment of the rollability of the vehicle is also advantageous, in particular when the vehicle is towed in such a way that at least one or more wheels of the vehicle are supported on a ground while the vehicle is towed, that is to say conveyed for example by means of a further motor vehicle and in the process is moved, in particular towed or pushed, for example along the ground. Here, the wheels of the vehicle can freely rotate without the wheels preventing the towing.Furthermore, DE 10 2013 001 880 A1 discloses a method for a vehicle in which vehicle state information is detected which comprises at least one transmission setting of a transmission of the vehicle. It is further provided that it is determined that the vehicle is towed if the vehicle state information always satisfies at least one condition of a predetermined amount of conditions during a predetermined period of time.DE 10 2015 212 558 A1 discloses a method for communicating a vehicle service installation, in particular a vehicle washing installation, with a first vehicle. In this case, it is provided that a vehicle communication device of the vehicle or a vehicle data communication device located in the vehicle transmits a first piece of vehicle information to a communication device of the vehicle service installation, wherein the transmission is preferably carried out wirelessly. The received first vehicle information is processed by a data processing device assigned to the vehicle service installation, the data processing device assigned to the vehicle service installation causes the vehicle service installation to perform an individual vehicle service measure that is individualized on the basis of the received first vehicle information.Furthermore, DE 10 2015 011 498 A1 discloses a method for carrying out a driving program, wherein the driving program can be provided and carried out by a control device of a motor vehicle. In the method, at least one parameter of at least one vehicle-side device is preset depending on the situation. In particular, a rollability can be created or maintained by the driving program.It is the object of the present invention to further develop a method of the type mentioned at the beginning in such a way that particularly simple and comfortable operation of the motor vehicle can be realized.This object is achieved according to the invention by a method having the features of claim 1. Advantageous embodiments with expedient developments of the invention are specified in the other claims.In the method according to the invention for operating a motor vehicle, in particular a motor vehicle such as a passenger car, for example, the rolling capability thereof is set by means of an electronic computing device of the motor vehicle.In order to be able to realize a particularly simple and in particular comfortable operation of the motor vehicle, it is provided in the method that the electronic computing device, which is designed for example as a control device or comprises a plurality of control devices, receives data, which characterize at least a part of a current environment of the motor vehicle, from at least one device external to the motor vehicle and thus different from the motor vehicle and sets the rollability of the motor vehicle as a function of the received data. In other words, it is provided according to the invention to take at least a part of the current environment of the motor vehicle into account when setting or activating the rollability of the motor vehicle, such that the rollability can be set particularly as required and particularly comfortably, in particular for the driver of the motor vehicle.The invention is based in particular on the finding that, for example, a driver of a conventional motor vehicle must manually deactivate functions such as, for example, a maneuvering brake function, an automatic starting aid and / or other functions, in particular brake functions, before the motor vehicle is conveyed through a car wash, for example, in order to avoid unexpected vehicle reactions being triggered when driving through the car wash. It is assumed here that the driver is skilled and / or can know, understand and operate functions which he must deactivate for a wash line pass in their entirety. Due to a possibly high number of assistance functions of a modern motor vehicle, the manual setting of the rollability may be uncomfortable for the driver. The object of the invention is now to simplify the setting of the rollability and thus, for example, the passing through wash lines and the towing of the motor vehicle in comparison with conventional methods in motor vehicles, in that the motor vehicle or its electronic computing device at least partially independently identifies the intention of the driver to set the rollability or situations in which the setting of the rollability is provided or advantageous, and consequently, for example, at least assists the driver in operating actions for setting the rollability in order to adapt the motor vehicle to the identified situation in a simple and comfortable manner for the driver. However, the setting of the rollability relates, for example, to all assistance functions, in particular with regard to a longitudinal and / or transverse guidance and to braking devices designed for braking the motor vehicle, which braking devices are set or deactivated, for example, when the rollability is set, in such a way that the motor vehicle is rollable, for example, and can subsequently be rolled by means of an external force or force acting from the outside on the motor vehicle and can be rolled, for example, along a floor. In particular, it is possible to set the rollability of the motor vehicle at least partially or completely automatically by means of the electronic computing device, so that the effort of the driver for setting the rollability can be kept low or even avoided. Passing through the wash line is to be understood in particular as meaning that the motor vehicle does not itself pass through the wash line, but rather that the motor vehicle is conveyed through the wash line by means of a conveying device of the wash line without the motor vehicle itself driving.In particular, it is conceivable to set further functions, in particular comfort functions, in particular automatically by means of the electronic computing device when setting the rollability. In this case, it is provided, for example, that when the rollability is adjusted by means of the electronic computing device, in particular automatically, the exterior mirror is pivoted and in this case, for example, folded onto a body of the motor vehicle, which is in particular designed as a self-supporting body, and / or window of the motor vehicle is closed and / or at least one seat system arranged in the interior of the motor vehicle is adjusted, in particular brought into a comfort position.By taking into account the current environment of the motor vehicle when setting the rollability, it is possible, for example, to offer or perform the setting of the rollability only when this is also meaningful or advantageous. Since the electronic computing device receives the data and thus information about at least the part of the current environment of the motor vehicle from the device different from the motor vehicle, the motor vehicle is not or not only dependent on the driver or on operating actions of the driver for setting the rollability, but the motor vehicle can recognize situations in which the setting or activation of the rollability is advantageous by itself and consequently support the driver particularly advantageously when setting the rollability.As indicated above, the rollability is understood to mean that, by adjusting the rollability or when the rollability is adjusted, the motor vehicle, in particular while it is supported via its wheels on a floor or a subgrade, can be rolled by means of an external force or force acting from the outside on the motor vehicle and thus in particular can be rolled along the floor without components such as in particular a transmission and / or a brake preventing such rolling of the motor vehicle, for example. Such an external force can be exerted on the motor vehicle, for example, by a conveying device external to the motor vehicle, in particular a wash line, so that, for example, the motor vehicle can be conveyed, in particular automatically, through the wash line by means of the conveying device and can be cleaned or washed automatically on the outer circumference. Furthermore, the aforementioned external force can act on the motor vehicle within the scope of a towing process, which is towed within the scope of the towing process, for example, by means of a further motor vehicle, in particular while at least one or more wheels of the motor vehicle are supported on the said floor. Because the rolling capability is set in this case, the at least one wheel supported on the ground during the towing process can roll along the ground or roll on the ground, so that the at least one wheel or the wheels do not prevent the towing process. The adjustment of the rollability can also be advantageous, for example, during maintenance work, during a change of wheels and then when the motor vehicle is located on a lifting platform and is subjected to a check, for example.According to the invention, it is provided that the electronic computing device provides a user, such as the driver of the motor vehicle, with at least one input possibility via at least one operating device, in particular the motor vehicle, arranged in the interior of the motor vehicle, as a function of the received data. Furthermore, it is provided that the electronic computing device receives at least one input effected by the user and dependent on the input possibility and automatically sets the rollability depending on the received input. In other words, an automatic adjustment of the rollability effected by the electronic computing device is omitted until the input is received. Only after receiving the input is the rollability automatically set by means of the electronic computing device. This makes it possible to ensure that the user actually wants to set the rollability, and therefore undesired or unnecessary setting of the rollability can be reliably avoided.The input possibility comprises a representation which is displayed on an electronic display of the operating device. The representation comprises, for example, at least two possible selections. The user can bring about the input, for example, via at least one operating element of the operating device, wherein the operating element can be designed, for example, as a rotary and / or push and / or slide position.By means of the operating element, the user can select one of the selection options, for example. By selecting a first of the options, the driver, for example, causes a first input which prevents automatic setting of the rollability. By selecting the second selection possibility, the driver, for example, brings about a second input, as a result of which the rollability is automatically set by means of the electronic computing device. The input possibility or the selection possibilities thus represent clear and simple operating suggestions for setting the rollability, in order to prepare the motor vehicle easily and comfortably for a process such as, for example, a passage of a wash line, a towing process or another process which requires the rollability of the motor vehicle. Such a preparation of the motor vehicle is also referred to as vehicle preparation and can be individually adapted to the respective situation or preconfigured, in particular by means of the electronic computing device.In order to be able to set the rollability particularly easily and comfortably, it is provided in a further embodiment of the invention that the electronic computing device receives the data via a wireless data connection between the electronic computing device and the device. For this purpose, the electronic computing device has, for example, a communication module which, with the device, at least indirectly establishes the said wireless data connection. Via the established wireless data connection, the data can then be sent from the device to the electronic computing device and received by the electronic computing device.In a further advantageous embodiment of the invention, the electronic computing device retrieves, as a function of the received data, at least one setting stored in a storage device, in particular the electronic computing device, and assigned to the part of the environment characterized by the data, and sets the rollability as a function of the retrieved setting. The roll capability is preconfigured, for example, by the stored setting. In this way, it is possible, for example, to assign different settings of the rollability to different locations at which the setting of the rollability is advantageous, so that the setting of the rollability can be adapted to the respective location as required. In this way, it is provided, for example, to fold the exterior mirrors at a first of the locations when setting the rollability, wherein, for example, folding of the exterior mirrors is omitted at a second of the locations when setting the rollability. Since the respective locations can be determined by the electronic computing device on the basis of the data, the different settings can be called up, in particular automatically, so that the different settings can be set particularly comfortably and easily and in particular automatically.The method enables, in particular, the realization of a central vehicle function of the motor vehicle, which generically prepares the motor vehicle for a respective imminent situation or for a respective imminent process. In this way, for example, the driving through a wash line, a towing process and further situations can be simplified for the driver of the motor vehicle by the motor vehicle recognizing the respective situation itself and proposing to the driver, for example, an operating action, in particular in the form of the input possibility, in order to adapt the motor vehicle to the situation, in particular automatically or at least partially automatically.In order to be able to determine a situation requiring the rolling capability of the motor vehicle particularly reliably and precisely, it is provided in a further embodiment of the invention that the electronic computing device receives the data from a further vehicle than the device, which is different from the motor vehicle. In other words, a further vehicle different from the motor vehicle is used as the device, as a result of which, for example, a car-to-car communication, i.e. a car-to-car communication, is provided. The device can furthermore be a device of an infrastructure, in particular of a traffic infrastructure. The data can thus be transmitted to the motor vehicle, for example, by car-to-x communication and received by the motor vehicle or by the electronic computing device.In a further refinement of the invention, the electronic computing device of the motor vehicle receives the data from a satellite-based navigation system as the device. In other words, in this embodiment, a satellite-based navigation system is used as the device, so that, for example, a current location of the motor vehicle and thus its environment can be determined particularly precisely. In this case, the data comprise, for example, GPS data or GPS coordinates (global positioning system), so that the location and thus the environment of the motor vehicle can be determined on a satellite basis. However, other satellite-based communication systems are readily alternatively or additionally conceivable.It is furthermore advantageous if, for example, a component of an infrastructure, in particular a traffic infrastructure, is used as the device, so that, for example, particularly precise information about the current environment of the motor vehicle can be obtained.In order to be able to set the rollability particularly securely and as required, it is provided in a further embodiment of the invention that the electronic computing device sets the rollability as a function of a current gear, in particular a transmission of the motor vehicle, selected by means of an operating element of the motor vehicle, which is also referred to as an actuating element. The driving state is understood to mean, for example, a set driving mode. The operating element for setting the gear is, for example, a selector lever for setting a plurality of gear stages, in particular the transmission. If, for example, the driving stage of the transmission set by means of the operating element is a neutral position, which is usually designated as N, so that the transmission is in neutral, for example, the electronic computing device can conclude that the driver intends or wishes to set the rollability. However, if the operating element is in a position such that a driving stage, in particular of the transmission, which is designed to bring about forward travel of the motor vehicle and is usually denoted by D is set by means of the operating element, the electronic computing device can, for example, conclude that the driver does not wish to set the rolling ability or does not intend to set the rolling ability, despite the fact that the data characterize an environment or a location at which the setting of the rolling ability would be advantageous. As a result, the electronic computing device can refrain from adjusting the rollability, so that undesirable adjustment of the rollability can be securely avoided. In particular, it can be provided that the electronic computing device sets the rollability or provides the input possibility when a time period during which the neutral position is set by the operating element and the motor vehicle is at a standstill exceeds a predefinable threshold value, whereby it can be securely concluded that the driver wishes or intends to set the rollability. Providing the input possibility is a so-called putting out of a query as to whether the motor vehicle is to be prepared for an imminent situation by setting the rollability. The driver can confirm or cancel the preparation of the motor vehicle in the manner described above by selecting the respective selection possibility.In particular, it can be provided that the electronic computing device sets the rollability as a function of a predeterminable period of time during which the motor vehicle is at a standstill. For example, the electronic computing device adjusts the rollability as a function of whether a time period during which the motor vehicle is at its standstill exceeds a predefinable threshold value.It is furthermore conceivable for the electronic computing device to set the rollability as a function of a state of at least one braking device and in particular when the at least one braking device is opened or when a time period during which the braking device is opened and for example the motor vehicle is at its standstill exceeds a predefinable threshold value. The background of these embodiments is in particular the automatic recognition or determination of the situation in which the setting of the rollability is advantageous to be linked to settings manual by the driver, for example in order to reliably set the rollability and to avoid undesired or unnecessary setting processes within the scope of which the rollability is set.A further embodiment is characterized in that the electronic computing device sets the rollability in that the electronic computing device automatically interrupts a force flow or frictional connection between wheels of the motor vehicle and a drive device of the motor vehicle configured to drive the wheels, in particular after receiving the input effected by the driver. For this purpose, at least one clutch is opened, in particular automatically, by the electronic computing device, for example.In a particularly advantageous embodiment of the invention, it is provided that the electronic computing device sets the rollability, in particular after receiving the input effected by the driver, in that the electronic computing device automatically opens or keeps open all braking devices of the motor vehicle configured to brake the motor vehicle. If the respective brake device is initially closed, for example, so that the respective brake device secures the motor vehicle against undesired rolling, the respective brake device is opened by means of the electronic computing device. If the respective brake device is already open, for example, the electronic computing device holds the respective brake device open, so that the brake device does not secure the motor vehicle against desired rolling.Finally, it has been shown to be particularly advantageous if the electronic computing device keeps at least one driver assistance system of the motor vehicle deactivated and / or deactivated when the rollability is adjusted. In this way, it can be ensured that, for example, a rolling process of the motor vehicle that takes place is interrupted in an undesired manner by means of an activated driver assistance system of the motor vehicle, so that the rolling process can be carried out advantageously and in particular without interruption.The exemplary embodiment explained below is a preferred embodiment of the invention. In the exemplary embodiment, the described components of the embodiment each represent individual features of the invention that are to be considered independently of one another and that develop the invention in each case also independently of one another and are therefore also to be considered as part of the invention individually or in a combination other than the combination shown. Furthermore, the described embodiment can also be supplemented by further features of the invention that have already been described.In the figures, elements having the same function are each provided with the same reference numerals.To this end, the single FIG. shows a flow chart for illustrating a method according to the invention for operating a motor vehicle.The single FIG. shows a flow chart for illustrating a method for operating a motor vehicle, which is designed, for example, as a motor vehicle, in particular as a passenger car. As will be explained below, within the scope of the method, the rolling capability thereof is set by means of an electronic computing device of the motor vehicle.The motor vehicle is designed, for example, as a multi-track motor vehicle and has at least two axles arranged one behind the other or one after the other in the longitudinal direction of the vehicle, with respective ground contact elements in the form of wheels. The wheels are rotatable relative to a body of the motor vehicle, which body is designed as a self-supporting body, for example, wherein the motor vehicle is supported, for example, via the wheels on a subgrade also referred to as the floor. If, for example, the motor vehicle is driven along the underlying surface, the wheels roll off on the underlying surface. For this purpose, the motor vehicle comprises a drive device, by means of which the wheels and thus the motor vehicle can be driven or are driven. The motor vehicle is designed, for example, as a hybrid or electric vehicle, so that the drive device has, for example, at least one electric machine for driving the wheels or the motor vehicle. Alternatively or additionally, the drive device can comprise at least one internal combustion engine, in particular designed as a reciprocating piston engine, for driving the wheels or the motor vehicle. The electric machine and the internal combustion engine are collectively also referred to as drive motors, by means of which the wheels or the motor vehicle can be driven.In particular, at least one clutch can be provided, which is arranged, for example, with respect to a force or torque flow between the wheels and the respective drive motor. The clutch can be opened and closed, for example. If the clutch is closed, for example, a power flow or frictional connection between the wheels and the respective drive motor is closed via the clutch, so that the wheels can be driven by the drive motor via the clutch. If the clutch is open, for example, the aforementioned power flow is interrupted, so that the wheels cannot be driven by the drive motor. The motor vehicle further comprises, for example, at least one or more braking devices for braking the motor vehicle. This braking of the motor vehicle is to be understood in particular as meaning that the motor vehicle which is initially moving and thus, for example, rolling, can be braked by means of the respective braking device and therefore slowed down and, in particular, brought to a standstill. Furthermore, braking of the motor vehicle can be understood to mean that the motor vehicle can be secured with the respective braking device against undesired rolling, in particular rolling away.The motor vehicle also comprises an electronic computing device, which can be designed as a control device or comprise a plurality of control devices. Furthermore, the driver of the motor vehicle is shown particularly schematically in the figure and denoted by 10.It is also conceivable for the motor vehicle, in particular the drive device, to have at least one transmission which has, for example, a plurality of driving stages which can be activated or engaged. If the transmission is designed as an automatic transmission, for example, one of the driving stages is usually designated as D, wherein this one driving stage D is designed to bring about a forward travel of the motor vehicle. At least one operating element, in particular designed as a selector lever, is provided here, for example, by means of which the driver 10 can select the respective gear stages. If the drive stage D is selected by means of the selector lever, then, for example, during a drive of the motor vehicle, different gear or transmission stages of the transmission are automatically engaged or activated and disengaged or deactivated by means of the electronic computing device, in particular by means of the transmission. In particular, an operating mode or a state can be used in the respective driving stage.Another of the gears is denoted by N, for example, and is a neutral position of the transmission. In the neutral position, for example, in particular in the transmission, the aforementioned force flow between the wheels and the drive motor is opened and thus interrupted. The power flow can thus be interrupted by opening the clutch. Alternatively or additionally, the force flow can be interrupted, for example, by setting the neutral position.The method begins at a block 12. At a first step S 1 of the method, the electronic computing device detects or determines that the driver 10 has shifted the selector lever into the drive position N or that the transmission is in the neutral position. In a second step S 2 of the method, which follows in particular the first step S 1, the electronic computing device receives data, which are also referred to as environmental data and characterize at least a part of a current environment of the motor vehicle, from at least one device external to the motor vehicle. This device external to the motor vehicle is, for example, a further vehicle different from the motor vehicle, a device of an infrastructure, in particular a traffic infrastructure, and / or a satellite-based navigation system. The environmental data characterize, for example, a current location of the motor vehicle on the earth, so that the electronic computing device, in particular a navigation device of the electronic computing device, can ascertain the current position of the motor vehicle on the earth. As a result, the electronic computing device can ascertain at least a part of the current environment of the motor vehicle, for example, in particular on the basis of the environment data. In other words, the environmental data represent information about the current environment of the motor vehicle.In a third step S 3 of the method, which step follows in particular the second step S 2, it is checked, in particular by the electronic computing device, whether settings are already present in a human-machine interface. This is explained in more detail below. If setting is already present and is thus known, then, for example, the third step S 3 is followed by a fourth step S 4. If there are not yet any settings present, in particular stored, at least one input effected by the driver 10 via the human-machine interface of the motor vehicle is received, for example, in a fifth step S 5 of the method, wherein, for example, the driver 10 selects at least one setting as part of the input. In particular, the fifth step S 5 is carried out alternatively to the fourth step S 4.In a sixth step S 6 of the method, the rolling capability of the motor vehicle is set, in particular automatically or at least partially automatically, by means of the electronic computing device, in particular as a function of the already present and thus known and stored settings, for example, or as a function of the input effected by the driver 10. In the sixth step S 6, the rollability is set as a function of the received environmental data, so that the motor vehicle is prepared as needed and particularly comfortably for an imminent situation or for an imminent process which is carried out at the current location of the motor vehicle.This situation or this process is, for example, a process 14 in the form of a washing process, within the scope of which the motor vehicle is conveyed through the wash line by means of a conveying device of a wash line which is external to the motor vehicle and thus different from the motor vehicle and is washed on the outer periphery side by means of the wash line and is thus cleaned. Since the rolling capability of the motor vehicle was set in a sixth step S 6 of the method, the conveying device can convey the motor vehicle through the wash line while, for example, the wheels of the motor vehicle roll along the aforementioned underlying surface.The already existing or known settings mentioned with respect to the fourth step S 4 are, in particular, settings which are stored, for example, in a storage device of the electronic computing device and are assigned to the locations determined on the basis of the environmental data. The stored settings are, for example, settings previously set by the driver 10, in particular via the human-machine interface, which, after they have been manually set by the driver 10, have been stored in the storage device. This was done, for example, when the motor vehicle was already previously located at the location. In the fourth step S 4, for example, the settings stored in the storage device are retrieved and implemented or set by the electronic computing device, in particular automatically.If, for example, no settings are yet assigned to the current location, so that no settings assigned to the location are yet stored in the storage device, for example because the motor vehicle is located for the first time at the location characterized by the environmental data, then the driver 10 can, for example, input and perform desired settings, in particular via the human-machine interface, in the fifth step S 5. It is conceivable that the settings made by the driver 10 in the fifth step S 5 are stored in the storage device and assigned to the current location. If the method is carried out for example a second time when the motor vehicle is again in the location, then, for example, instead of the fifth step S 5, the fourth step S 4 is then carried out, in which the previously stored settings are retrieved from the storage device.The human-machine interface is also referred to as an HMI, for example, and comprises in particular an operating device which has, for example, at least one electronic display which is arranged in the interior of the motor vehicle and is also referred to as a screen. The operating device can furthermore have at least one further operating element which is different from the previously mentioned selector lever and is additionally provided, which is designed, for example, as a rotary and / or push and / or slide actuator. By way of the further operating element, the driver 10 can, for example, effect inputs into the operating device and thus into the human-machine interface and thereby make the settings. Graphics and / or symbols and / or letters and / or numbers illustrating the settings can be displayed on the display in particular.By setting or activating the rollability, the motor vehicle is not secured. This means that by adjusting the rollability, the motor vehicle is not secured against rolling, since such rolling is desired in the aforementioned situation or within the scope of the aforementioned process.The method can have a seventh step S 7, in which, for example, the rolling capability is deactivated, in particular automatically, by means of the electronic computing device. In an eighth step S 8 of the method, it is detected, for example, by means of the electronic computing device that the driver 10 sets the driving gear D or a driving gear of the transmission, which is usually designated by R and is designed to bring about a reverse travel of the motor vehicle. In a ninth step S 9 of the method, it is detected, for example, that a current speed of the motor vehicle exceeds a predefinable threshold value. In a tenth step S 10 of the method, for example, an input effected by the driver 10 via the operating device and characterizing an activation of the rollability is detected. In an eleventh step S 11 of the method, for example, in particular by the electronic computing device, an input effected by the driver 10 and characterizing, for example, an activation of at least one braking device of the motor vehicle is detected. The driver 10 can bring about the input characterizing the activation of the at least one brake device, for example, by means of the selector lever, by means of the operating device or by means of an operating element different therefrom, in particular arranged in the interior. The at least one brake device is, for example, a parking brake, in particular an electric parking brake, of the motor vehicle. Alternatively or additionally, the at least one brake device can be a parking lock of the transmission, which is usually activated in such a way that the driver 10 moves the selector lever and thereby engages one of the gear stages, which is usually designated P.If it is now detected in the context of the seventh step S 7 that the driver 10 has engaged the driving gear D or the driving gear R and the speed exceeds the predefinable threshold value, or that the driver 10 has effected an input characterizing the deactivation of the rollability into the operating device or has effected an input characterizing the activation of the at least one brake device, the rollability is deactivated, in particular by the aforementioned force flow between the wheels and the drive motor being closed and / or the at least one brake device being activated.The aforementioned settings manually carried out by the driver 10 are stored, for example, in a twelfth step S 12 of the method. Likewise, for example, the environment data is stored and assigned to the stored settings. The stored settings or settings manually carried out by the driver 10 are denoted by 16 in the FIG. and relate, for example, to the setting of the rollability per se and, if appropriate, to further functions. A first of the further functions is, for example, that when the rollability is adjusted, at least one windshield wiper of the motor vehicle is deactivated. A second of the functions comprises, for example, folding outside mirrors of the motor vehicle and thus folding them onto the superstructure. A third of the functions comprises, for example, that at least one driver assistance system or a plurality of driver assistance systems such as, for example, parking or distance sensors, etc., are deactivated, so that the driver assistance systems do not interrupt the process 14 and permit a comfortable and pleasant performance of the process. In the sixth step S 6, the settings 16 retrieved or manually carried out by the driver 10 are implemented, i.e. set, so that-as described above-the windshield wiper is deactivated and / or the mirrors are folded and / or the driver assistance systems are deactivated.In particular, it is provided that, in the fourth step S 4 and / or in the fifth step S 5 and / or in the sixth step S 6, the electronic computing device provides the driver 10 with an input possibility 18 with selection possibilities 20 and 22 via the operating device as a function of the environmental data. The driver 10 can select one of the selection options 20 and 22 by means of the further operating element of the operating device, wherein the electronic computing device receives the selected selection option 20 or 22 as input by the driver 10. Depending on the input received, i.e. depending on the selection possibility 20 or 22 selected by the driver 10, the rollability is then automatically set by the electronic computing device, for example, so that the rollability is automatically set after receiving the input.If, for example, the driver 10 selects the selection possibility 22 by means of the further operating element, then, for example, the stored settings are retrieved in the fourth step S 4 or the driver 10 can manually perform the settings in the fifth step S 5, in particular via a selection menu, whereupon the rollability is set in the sixth step S 6 as a function of the environmental data and as a function of the settings. If, however, the driver 10 selects the selection option 20, then, for example in a thirteenth step S 13, no settings for selection are offered to the driver 10, since the driver 10 does not intend or want to set the rollability. Subsequently, for example, in a fourteenth step S 14, the motor vehicle is secured, in particular against rolling, by, for example, activating the at least one brake device.Overall, it can be seen that the setting of the rollability takes into account both the environmental data and manual inputs of the driver 10 in order to be able to set the rollability securely and as required. By taking into account the environmental data, a respective situation in which the rollability is advantageous can be automatically recognized by the electronic computing device, so that the driver 10 can be advantageously supported when setting the rollability. As a result, the motor vehicle can be operated and operated particularly easily and comfortably.List of reference characters10 Driver 12 Block 14 Process 16 Setting 18 Input possibility 20 Selection possibility 22 Selection possibility S 1 First step S 2 Second step S 3 Third step S 4 Fourth step S 5 Fifth step S 6 Sixth step S 7 Seventh step S 8 Eighth step S 9 Ninth step S 10 Tenth step S 11 Eleventh step S 12 Twelfth step S 13 Thirteenth step S 14 Fourteenth step
