Method for operating a control device for a motor vehicle, control device for a motor vehicle and motor vehicle with such a control device

The invention relates to a method for operating a control device for a

Motor vehicle, a control device for a motor vehicle, which is designed to carry out such a method, and a motor vehicle with such

Control device.

A parking fee for a parking transaction in a paid parking lot can often be paid today using an electronic parking ticket, which can be purchased, for example, using an application designed for this purpose on a mobile device, such as a smartphone. Various parking service providers already exist for this purpose, each of which, for example, enables their customers to use their own application for the corresponding parking fee to be debited, for example, from a customer's bank account and forwarded to the corresponding parking space provider, which is, for example, a city administration.

If there are several parking service providers available whose application can be used, for example, to transfer a parking fee to a parking lot provider, it must be possible for a controller to see from outside, for example, via which parking service provider the fee was paid, so that a parking authorization of the respective motor vehicle can be checked by the controller . For this purpose, for example, a corresponding parking service provider symbol can be arranged as a sticker in the area of a windshield of the motor vehicle.

DE 10 2013 015 704 A1 describes a method for signaling an impending parking phase of a motor vehicle. Here, using a

Monitoring device detects a geographical position of the motor vehicle and / or a respective state of at least one vehicle component of the motor vehicle. If it is recognized that the motor vehicle is starting a parking phase in a parking space monitored by the monitoring device, a maximum parking period can be determined and an automatic payment process can be carried out for the beginning parking phase. DE 10 2016 124 604 A1 describes a method for assigning a vehicle to a parking space, sensors being used to detect that the vehicle is driving into the parking space. In addition, it is recorded when the vehicle leaves the parking lot, so that finally a parking fee for a parking time actually spent in the parking lot can be paid automatically with a final payment process.

DE 10 2014 013 271 A1 describes a device for displaying information on a window of a motor vehicle. Information relating to a parking process can be displayed on this display, for example a parking period or a QR code, which can contain, for example, information for identifying the motor vehicle and information relating to the parking process.

DE 20 2015 003 921 U1 describes a head-up display which, by redirecting the projection, can reflect a wide variety of information to the outside. This diverse information is, for example, a parking period, so that a kind of digital parking ticket can be shown on the redirected head-up display.

DE 10 2005 032 718 A1 describes a system for paying parking fees for a vehicle parked in a parking lot. A payment process for a parking fee can be carried out using a smartphone. In addition, a character code for a controller is displayed on the motor vehicle and can be decrypted using a mobile control device. The controller can use the decrypted character code to determine, for example, the duration of the parking and the date and time when the parking started.

DE 10 2015 207 648 A1 describes a method for displaying a parking authorization of a motor vehicle by means of a parking authorization display device. This parking authorization display device shows, among other things, an arrival time and a parking authorization, for example by means of a QR code. In this case, the geographic position of the motor vehicle is also determined by means of a parking position determining device arranged in the motor vehicle. This can be used to determine whether one and which of possibly even several parking authorizations is required in order to park the motor vehicle at the geographical position of the motor vehicle.

Furthermore, more and more motor vehicles nowadays have a battery which is designed to supply an electrical drive machine of the respective motor vehicle with electrical energy. For such a motor vehicle, it makes sense to carry out a parking process on a parking space of a parking lot with a charging process at one of the To connect parking space assigned loading device. However, often only a small number of charging devices are available, so that, for example, a certain charging device can be accessed from several parking spaces or only a part of the parking spaces of the parking lot has a respective access to a charging device.

It is the object of the invention to provide a solution with which information relating to a parking process of a motor vehicle and particularly simply and quickly information relating to a charging process of a motor vehicle can be viewed particularly easily and quickly with an external charging device.

This object is achieved by the subject matter of the independent claims. Advantageous refinements with expedient and non-trivial developments of the invention are specified in the dependent claims, the following description and the figures.

The inventive method for operating a control device for a

Motor vehicle comprises the following steps carried out by means of the control device:

First of all, the respective settings relating to a desired parking procedure of the motor vehicle on a parking space are detected by means of a selection device and made available to the control device. The selection device with which these settings are recorded is, for example, an im

Selection device arranged inside the motor vehicle of a display device or a mobile terminal of a user of the motor vehicle. By means of this selection device, for example, a desired parking time on the parking space or a desired end time of the parking process of the motor vehicle on the parking space can be entered by a user of the motor vehicle and recorded by the selection device. In addition to the settings relating to a desired parking process for the motor vehicle on the parking space, settings relating to a choice of a parking service provider for the parking process are processed by the control device. If more

Providing parking service providers with the service of enabling a parking fee to be paid for the desired parking procedure of the motor vehicle on the parking space, the choice of the parking service provider offers the user of the motor vehicle the possibility to select the parking service provider who, for example, requires the lowest fees for the payment process. As an alternative or in addition to this, the user can select the parking service provider with whom, for example, he has already created a user profile and stored his billing data, so that by choosing this parking service provider he can always promptly and reliably initiate a payment process for a parking fee for the parking process.

Alternatively or in addition to the settings regarding the choice of one

Parking service providers for the parking process are processed by the control device settings relating to a charging process of a battery of the motor vehicle by means of a charging device assigned to the parking space. In this case, for example, the detected settings can be processed, which relate to charging a high-voltage battery of the motor vehicle, which is designed to supply an electrical drive machine of the motor vehicle with energy. Such settings regarding a charging process of a battery of the motor vehicle include, for example, a minimum charging time in which the battery of the motor vehicle is charged by means of the charging device. In the

Charging device can be, for example, a charging station, which is arranged next to the parking space on which the motor vehicle performs the desired parking process. This loading device can be designed, for example, with a

To be connected to a motor vehicle that is parked in one of several parking spaces adjacent to the loading device. A charging device can thus be shared by several parking spaces, but it only allows one charging process at a time, for example. Vehicles which are located in the other parking spaces assigned to the corresponding charging device cannot therefore carry out a charging process at the same time, but must alternate in this regard.

In a further method step, a payment process for a parking fee for the set parking process is initiated by the selected parking service provider. On the basis of the settings provided regarding the desired parking process of the motor vehicle on the parking space and also taking into account the recorded choice of the parking service provider for the parking process, the settings can thus be processed such that the parking service provider pays the corresponding parking fee for the desired parking time on the parking space becomes. The prerequisite for this is that the user-specific data required for initiating the payment process is stored in the control device and / or is stored in the selection device, which is, for example, a mobile terminal of the user, and is made available to the control device. These

User-specific data include, for example, account or credit card data. The user of the motor vehicle therefore only has to select the parking service provider from, for example, a list of parking service providers and to specify the desired parking process, for example with regard to a parking period, so that the control device the payment process based on these settings

accruing parking fee is automatically initiated.

Alternatively or in addition to this, the charging process set for the battery is initiated by means of the charging device. In this case, the corresponding settings provided relating to the charging process and processed by the control device are taken into account, so that, for example, the set minimum charging time of the battery is at least waited until, for example, a charging process of the battery with the

Charger is automatically ended.

In a third method step, a display device of the motor vehicle, which is visible from the outside, is activated for displaying at least one piece of information relating to the parking process based on the detected settings. The display device, which is visible from the outside, is, for example, one in an outer wall of the

Motor vehicle integrated display device or, for example, around a rotatable display that can be rotated such that it can be seen, for example, when a person looks through a windshield of the motor vehicle. Information is now displayed by means of the display device, such as an expiring parking meter, which indicates the remaining parking time. The information that is displayed here on the display device becomes the previously processed settings relating to the

desired parking process of the motor vehicle and the selected one

Taken from parking service providers. It is particularly advantageous to display the parking service provider, for example as a corresponding symbol of the selected parking service provider. Using this information, a controller who wants to check whether the motor vehicle has paid a parking fee for the parking process on the parking space can request corresponding information from the parking service provider, via whom the payment process was carried out, without first having to find this provider. On the one hand, this means that it is no longer necessary, for example, to use a sticker on the windshield to indicate which one

Parking service provider the parking process was paid for. On the other hand, the user can, for example, sometimes take into account one or another parking service provider, taking into account current fee specifications, without having to change the sticker on the windshield, for example. In this way, for example, the parking service provider who offers the most advantageous conditions for the user of the motor vehicle can be selected at any time. In this context, the price comparison between different parking service providers is already particularly advantageous for the user of the motor vehicle through the settings regarding the choice of the parking service provider for the parking process. In addition, a controller can check whether the fee has actually been paid, for example using a cloud-based application. A QR code on the display device is suitable for this, for example, so that the controller only has to scan this QR code in order to be able to look up and check all the information required for the parking process. For a third party who, for example, would also like to park on the parking space with a motor vehicle, this also makes it possible for him to see an overview of how long the parking space is likely to be occupied by the motor vehicle. With a displayed remaining parking time of ten minutes, the user can decide, for example, whether he would like to wait another ten minutes until the user of the

Motor vehicle is expected to return to his motor vehicle, then his vehicle in that same parking space after the user has his motor vehicle

has left to park. For the user of the motor vehicle, it is also no longer necessary to first go to a ticket machine, for example on foot, and to buy a parking ticket, since he can only purchase a parking ticket for a desired parking process on the parking space by means of the selection device and the method according to the invention is also automatically displayed from the outside in the motor vehicle and / or on the motor vehicle.

As an alternative or in addition to this, a display device of the motor vehicle, which can be viewed from the outside, is activated for displaying at least one item of information relating to the charging process based on the detected settings. Information is now displayed by means of the display device, for example a charging process clock, which shows the remaining charging time during which the motor vehicle is coupled to the

Charger is necessary, can be seen. The information that is on the

Display device are shown, are taken from the previously processed settings regarding the charging process. A third party, who also wishes to charge a battery of his vehicle with the charging device currently occupied by the motor vehicle, can also estimate when the charging device could be available again for his vehicle for a further charging process. This makes it easier, for example

Scheduling both the user of the motor vehicle and third parties who are interested in a charging process with the charging device.

The information is only stored on the

Display device displayed, namely whenever a sensor device of the display device a person in a predetermined environment of the display device detected. The display is thus not, for example, constantly illuminated to save energy, but only when a person approaches the display device so closely that it can be assumed that the display device is interested in the information that can be displayed by the display device.

The invention also includes embodiments which result in additional advantages.

One aspect of the method according to the invention relates to operating the display device by means of the control device as an electronic parking disk and parking ticket, and a

Processing the payment process for the parking process via a selected one

Parking service provider. In an advantageous embodiment of the invention, it is therefore provided that at least one of the following information is displayed by means of the display device as at least one piece of information relating to the parking process:

A desired parking time recorded as a setting on the parking space; a remaining parking time of the motor vehicle on the parking space; a time at which parking on the parking space began; the parking service provider. For example, both the starting time of the parking process and the total desired parking time started at this time can be displayed. If the parking process on the parking space begins at 2:05 p.m., for example, this time and the desired parking time of three hours can be displayed. Alternatively or in addition, the remaining parking time can be displayed, so that, for example, at 2:10 p.m. a remaining parking time of 2 hours 55 minutes would be displayed. Additionally or alternatively, the parking service provider is, for example, using a

corresponding symbol is displayed. The information mentioned can also be displayed by means of a QR code or another coded symbol such that this information can be decrypted using a controller's mobile device and used to check the payment of the parking fee for the parking process. It is thus possible to use the control device to implement a digital parking disc and a digital parking meter, via which a corresponding registration for initiating a payment process for the parking fee for the set parking process is processed at a selected parking service provider. As a result, the parking time of the electronic parking meter is shown particularly well from the outside and, on the other hand, the effort for the user of the motor vehicle with regard to acquiring a parking permit on the parking space is kept particularly low, since the display device functions as a digital parking ticket. Another aspect of the method according to the invention relates to the charging process of the battery of the motor vehicle. In an advantageous embodiment of the invention, it is therefore provided that at least one of the following settings relating to the charging process is recorded by means of the selection device: a desired charging time of the battery; a desired range of the motor vehicle after the charging process, on the basis of which a state of charge of the battery is determined; an energy provider from whom the energy for charging the battery is obtained. The period for which the motor vehicle must at least be coupled to the charging device assigned to the parking space can thus either be based on a desired charging time and / or on the basis of a desired one

Range that is to be achieved by the charging process for the motor vehicle. In addition, a desired energy provider can be selected, for example, from a plurality of possible energy providers. This enables, for example, a price comparison between different

Energy providers is possible, so that the user of the motor vehicle can select the energy provider from which he can currently obtain the energy for charging the battery in a particularly cost-effective manner.

By means of the display device, at least one of the following information is now displayed as at least one item of information relating to the charging process: a remaining charging time of the battery of the external charging device; a time at which charging of the battery of the external charger started; the desired charging time; the energy provider from whom the energy for charging the battery is obtained. Based on this information, it is therefore possible to see from outside the motor vehicle how long the

Charger is expected to need for charging the battery of the motor vehicle. In addition, for example, a third party who, for example, also wants a charging process for the charging device for his motor vehicle, can contain an indication of when he is likely to be able to charge his motor vehicle, but also which energy provider is currently making particularly cheap energy available for charging the battery. The corresponding information can be displayed using a QR code, for example. Using this QR code, the interested third party can use a mobile device to call up information about current electricity prices from various energy providers, for example. This aspect of the invention is generally based on the knowledge that, in particular if only one charging device is provided for a plurality of parking spaces, a third party who also carries out a charging process with the

Charger desires to include information about when the charger is likely to be available to charge another vehicle. This is done by displaying the information regarding the charging process on the Display device reached. As a result, the load on the charging device can ultimately be made particularly efficient, since, for example, as soon as the battery is charged but the motor vehicle remains parked, for example the charging device can be released for another motor vehicle.

A further embodiment of the invention provides that the motor vehicle is coupled to the external one before the charging process is started

Charging device, with which the charging process of the battery is locked. These

Coupling is only unlocked when at least one of the following conditions is met: The desired charging time of the battery has passed; the state of charge of the desired battery, which was determined on the basis of the desired range of the motor vehicle, has been reached; the control unit receives an unlocking signal from a mobile terminal of a user of the motor vehicle. So that the charging process of the battery of the motor vehicle can be carried out in a particularly secure manner, for example by energy transmission via a cable connection between the charging device and the motor vehicle, this coupling is usually implemented as a coupling that cannot be released easily. For example, the

Control device on the basis of which this locking takes place, the cable that connects the charging device to the motor vehicle cannot be disconnected by a third party, since, for example, a corresponding plug connection must first be unlocked by the user of the motor vehicle before it can be opened .

This ensures that an unauthorized third party does not interrupt the charging process without the user of the motor vehicle requesting this. As soon as the desired charging time has passed or when the desired state of charge has been reached, however, this coupling between the motor vehicle and the charging device can be unlocked automatically. A third party who wants to charge his vehicle using the charging device and sees that the charging process of the motor vehicle will be completed in a few minutes can thus wait for these minutes and, after these have elapsed, disconnect the motor vehicle from the charging device, that is to say, for example remove the cable and use it to connect your own vehicle to the charger for charging. As an alternative or in addition to the above-mentioned conditions for unlocking the coupling, provision can also be made for this unlocking to only ever take place if the user of the motor vehicle agrees to the unlocking. For this purpose, the latter can send a corresponding locking signal from a mobile terminal, for example a smartphone, to the control unit, which then receives this signal and then unlocks the coupling between the motor vehicle and the charging device. This unlocking signal can be independent of reaching the desired state of charge and / or the passing of the desired charging time can be received by the control unit. This enables the charging device to be used for several vehicles and motor vehicles in the vicinity of the charging device, regardless of the duration of a parking process of the motor vehicle on the parking space. This aspect of the method according to the invention is therefore based on the knowledge that with a smaller number of accesses to loading devices compared to a number of parking spaces, a particularly high utilization of the respective accesses to the respective loading devices is always achieved when automatic unlocking and / or unlocking at the request of a third party, the coupling of the motor vehicle to the charging device is made possible.

In a further advantageous embodiment of the invention, it is provided that if the control device receives a charging request from a user of another motor vehicle, the received charging request is sent to the mobile terminal of the user of the

Motor vehicle transmitted and waiting to receive a response signal from the user of the motor vehicle. A third party who wishes to be, for example

Motor vehicle or its vehicle is charged by the charging device can thus, for example, by scanning a QR code displayed on the display device of the motor vehicle, cause it to use its mobile terminal

Charge request via the control device to the user's mobile terminal

Motor vehicle sends. The charging request contains, for example, the request whether the user of the motor vehicle agrees to promptly end the charging process of his battery and to release the charging device for the other user who has made the charging request. However, the coupling of the motor vehicle to the external charging device is only unlocked if the unlocking signal is received as a response signal. The user of the motor vehicle must therefore agree to the charging request so that the charging process of his motor vehicle is terminated, for example although the desired charging time has not yet elapsed, and the charging device is released for the other user, that is to say a third party. It is therefore at the discretion of the

User of the motor vehicle whether he is on such a charging request from another

Respond to the user and wants to follow or not. The user of the currently charging motor vehicle thus remains in control of the coupling of his motor vehicle to the external charging device. The requests from third parties for unlocking the coupling between the motor vehicle and the charging device can thus be processed by the control device as part of the method. Alternatively or in addition, inquiries from the other user regarding the parking process can be transmitted to the user of the motor vehicle, by means of which the other user can ask, for example, after the motor vehicle parking process has ended earlier on the parking space than is displayed on the display device of the motor vehicle.

In a further particularly advantageous embodiment of the invention, at least one of the following is provided by means of the display device

Information is displayed: an availability of the motor vehicle as a rental vehicle; a rental vehicle provider who provides the motor vehicle as a rental vehicle. The display device can thus also be used to indicate to a person passing by the motor vehicle that this motor vehicle is available as a rental vehicle, for example as part of a so-called car sharing offer. For example, it can be made particularly easy for this person passing by using a corresponding QR code displayed on the display device, which is arranged, for example, next to a corresponding symbol of a rental vehicle provider, simply by scanning this QR code with a mobile device to the user

Rental vehicle providers to be referred so that the person passing by can borrow the motor vehicle available as a rental vehicle particularly quickly and with very little effort. As an alternative or in addition, corresponding information relating to a ride sharing offer by the user of the motor vehicle can be made known to third parties by means of the display device and the information displayed thereon.

According to the invention, a control device for a motor vehicle is also provided. This control device has a processor device which is designed to: The respective setting detected on a selection device and made available to the control device regarding a parking process of the motor vehicle in a parking space and additionally regarding a choice of a parking service provider for the parking process and / or a charging process of a battery of the motor vehicle by means of one the parking space

to process assigned loading device; to initiate a payment process for a payment fee for the set parking process at the selected parking service provider and / or the set charging process; one visible from the outside

Control display device of the motor vehicle for displaying at least one piece of information relating to the parking process and / or the charging process based on the detected settings. The preferred embodiments presented in connection with the method according to the invention and their advantages apply accordingly, as far as applicable, to the control device according to the invention for a motor vehicle. Especially the control device is designed to lock and unlock a coupling of the motor vehicle to the external charging device. The processor device can have at least one microprocessor and / or at least one microcontroller. Furthermore, the processor device can have a program code which is set up to carry out the embodiment of the method according to the invention when executed by the processor device. The program code can be in one

Data memory of the processor device can be stored.

An advantageous embodiment of the control device according to the invention provides that the control device has the controllable display device for displaying the at least information relating to the parking process or the charging process

Motor vehicle includes. The control device can thus be integrated in the display device, which is designed, for example, as a display device that can be seen through the windshield. This makes it particularly economical and space-saving

Realization of the control device enables, in particular, no additional

Display devices that are spatially separated from the control device are required.

A further advantageous embodiment of the control device according to the invention provides that the display device of the control device also includes the selection device, the display device being designed to transmit the settings detected by means of the selection device to the control device. The display device can therefore have, for example, a touch-sensitive control panel, for example a so-called touch surface, on which the settings of the user of the motor vehicle can be recorded and transmitted from there to the control device. There is therefore no need for a selection device that is spatially separate from the display device. If the display device with an integrated selection device is additionally integrated in the control device, the control device can be arranged in a particularly space-saving manner in the motor vehicle.

According to the invention, a motor vehicle with a control device as described above is also provided. The one controlled by the control device

The display device is designed as a display device integrated in an outer wall of the motor vehicle. This display device can be, for example, one integrated in one of the side walls of the motor vehicle and with one

act touch-sensitive control panel designed display device. The settings detected by means of the selection device can be made directly on the outer wall of the Motor vehicle be made. As an alternative to this, the settings can be made from a selection device inside the motor vehicle to the display device by means of the

Control device are transmitted and / or corresponding settings are made in a smartphone, that is, in a mobile device of the user, which are then controlled by the control device by appropriate control of the

Display device can be displayed on the display device in the outer wall of the motor vehicle. The preferred embodiments presented in connection with the control device according to the invention and the method according to the invention and their advantages apply accordingly, as far as applicable, to the invention

With a swiping gesture, for example, a message can be sent to the user 40 of the motor vehicle 10, that is to say, for example, to its mobile terminal 41. This message can contain, for example, the question of whether a parking end or, for example, a loading end has already been sent by the user earlier than before 40 is possible in a planned manner since, for example, the third party 42, who writes the corresponding message, also wishes to park in the parking space 12 and / or to charge the charging device 14. After the user 40 has been approved, the coupling between the motor vehicle 10 and the charging device 14 can be released, that is to say unlocked, so that the third party 42 can, for example, couple his motor vehicle 10 ′ to the charging device 14. If the motor vehicle 10 is currently being charged, the message can be displayed on the display device 24: “Charging is in progress!”. A display of the remaining parking time and / or charging time is also suitable, for example in the form of an expiring parking meter. The QR code 34 can in this case, for example, only be offered when exiting the motor vehicle 10 after having previously, for example, via a corresponding communication link 27 was requested between the control device 20 and an external server device, this external server device having provided information about all possible and / or available parking service providers 30.
