Description

Technical Field

[0001] This invention relates to a system and method for communicating with a motor vehicle. Background Technology

[0002] Digital networking between people is constantly evolving. Here, social media applications are commonly used to connect, enabling communication and the sending of messages and / or media content. A range of providers of social media applications exist, such as commercial or non-commercial providers. By creating social media profiles with relevant providers, people in a community can connect through these providers to use social media applications. For example, text, especially text messages and / or voice messages, can be exchanged using social media applications. Some providers of social media applications for communication between people include, for example, WhatsApp. TM Threema TM Facebook TM Twitter TM Signal TM or iChat TM .

[0003] Networking with objects is also increasing. For example, motor vehicles are already connected to servers, especially fleet servers, which are often run by the vehicle manufacturers. This allows users to query data from the vehicles and remotely control vehicle functions, typically using applications or remote controls provided by the vehicle manufacturers. For example, one could query the state of charge of a high-voltage battery or activate a parking heater.

[0004] For example, DE 10 2016 008 396 A1 includes a system for wirelessly controlling vehicle functions, wherein a communication module enables wireless communication between the vehicle's controller and a remote controller.

[0005] Software applications and logic for modifying settings of autonomous vehicles are known from US 10 334 050 B2.

[0006] CN 108391004A includes a vehicle control system and method based on a mobile phone application, wherein a preset instruction is sent to an SMS controller via the mobile phone application, and the SMS controller forwards the received instruction to the vehicle controller, which then controls the corresponding functional device to implement the instruction.

[0007] A disadvantage of known devices and methods is that, in order to communicate with a motor vehicle, the user needs a special application provided by the manufacturer, which must first be installed on their mobile terminal device. The user must also learn the application and how it works. For example, the user must familiarize themselves with the menu structure before they can effectively use the application. Summary of the Invention

[0008] The purpose of this invention is to facilitate communication with motor vehicles.

[0009] This objective is achieved through the independent claims. Advantageous improvements of the invention are disclosed in the dependent claims, the following description, and the accompanying drawings.

[0010] This invention is based on the fundamental concept of using existing social media applications familiar to users for communication, particularly for controlling and querying / retrieval of vehicle parameters. Preferably, users do not need to learn fixed commands and instructions; instead, the commands can be extracted from sent messages.

[0011] This invention provides a method for communicating with a motor vehicle. The method includes: step a) providing at least one social media interface for communicating with the motor vehicle on a pre-defined fleet server, wherein communication is provided via a social media application through the social media interface. The fleet server is preferably an external server for the vehicle, which may be operated by the vehicle manufacturer, for example. However, the social media application may also be provided by a non-vehicle manufacturer. The social media application is preferably freely selectable according to the user's wishes and preferences. Preferably, a social media application is used where message exchange, i.e., communication, can occur between different users. This means that at least text messages and / or voice messages can be sent. Alternatively, video messages can also be sent for communication. The social media interface provided on the fleet server refers to an interface, especially a software interface, that can receive messages and provide additional programs through the social media application. Preferably, the social media interface can be designed as a program element on the fleet server, wherein the program element can emulate a receiving device, such as another mobile terminal device with a social media application. Particularly preferably, social media profiles of the motor vehicle can be created in the previous step, i.e., profiles / archives of the motor vehicle can be created on behalf of the social media application provider.

[0012] In another step, the method includes: step b) receiving a message from a mobile terminal device via a social media application through a pre-defined social media interface of a fleet server. Thus, the mobile terminal device can, for example, use a social media application to compose a message and send it to the social media interface of the fleet server via the social media application, where a social media interface can be assigned to a vehicle. That is, preferably, the social media interface can have a clear assignment relationship with the vehicle, for example, through a vehicle identification number (VIN). Therefore, the vehicle is associated with the provider of the social media application. Alternatively, the social media interface cannot be directly associated with the vehicle, but only with the vehicle manufacturer. In this case, for example, the assignment to a matching vehicle can be performed based on the identification of the mobile terminal device from which the message originates. Here, for example, a mobile phone, especially a smartphone, tablet, or smartwatch can be used as the mobile terminal device.

[0013] Subsequently, in step c), a vehicle function call can be determined from the received message by an interpreter, wherein the semantics of the message are interpreted by the interpreter to determine the vehicle function call. Here, a vehicle function call may be, for example, a query and / or adjustment of vehicle parameters, wherein vehicle parameters may be, for example, sensor measurements from vehicle sensors, such as current / voltage sensors, temperature sensors, and brightness sensors. Alternatively or additionally, vehicle parameters can also be set or adjusted via a vehicle function call. For example, the interior temperature of a vehicle can be adjusted using a vehicle function call. Therefore, a vehicle function call is an instruction or control command used to query and / or adjust vehicle parameters.

[0014] However, instead of requiring precise control commands, i.e., correct representations of vehicle function calls, in the received message, the interpreter can analyze the message's semantics to extract the vehicle function calls. To do this, the interpreter can, for example, analyze the sentence or word patterns of the message and compare them with similar patterns, for example, pre-set in a database. If consistency is found, the interpretation of the message can be determined. In particular, it can be determined which vehicle function call is present in the message or whether the vehicle function call actually exists in the message; if no vehicle function call is found, the method can be terminated.

[0015] After determining the vehicle function call, the method includes: in step d), executing the determined vehicle function call in the motor vehicle, wherein the fleet server accesses the motor vehicle via a vehicle interface to execute the function call; and as in step e), if the fleet server obtains vehicle parameters from the motor vehicle as a response to the vehicle function call, then a response message is sent from the fleet server to a mobile terminal device via a social media application, wherein the response message is generated based on the obtained vehicle parameters. In other words, after determining the vehicle function call, the fleet server drives the motor vehicle to execute the vehicle function to which the motor vehicle belongs. This means that vehicle parameters can be queried or adjusted. Preferably, for this purpose, the fleet server may have a vehicle interface that sends the vehicle function call to the motor vehicle, such as the motor vehicle's controller. After executing the vehicle function call, it can be checked whether vehicle parameters, as a response to the vehicle function call, have been sent from the motor vehicle to the fleet server. If no vehicle parameters are sent, then the method can end at this point. For example, if only one vehicle parameter should be adjusted, but no feedback is needed. However, if vehicle parameters are obtained, then the fleet server can create a response message after obtaining the vehicle parameters and send it to the mobile terminal device via a social media application. Preferably, the response message is a text or voice message generated by the fleet server and in which vehicle parameters are inserted or embedded. This means that vehicle parameters are not only sent as single numerical values ​​in the response message, but can also be integrated into a complete response sentence. Therefore, the initial message for social media profiles from a mobile device to a vehicle could be, for example, asking "How full is the battery?". Thus, an interpreter can determine that a query for the vehicle battery's "state of charge" should be performed via a vehicle function call. After querying this vehicle parameter, i.e., the battery's state of charge, a sentence such as "Vehicle battery charged to 87%" can be automatically created as the response message. The response message can be generated, for example, by a chatbot in the fleet server, in a manner that, for example, a database generates the response message based on the queried vehicle parameters.

[0016] The present invention offers the following advantages: users do not need to install additional applications on their mobile devices, and they can communicate with vehicles through their preferred medium. Therefore, users do not need to learn how to operate new applications and can communicate with their vehicles without leaving their preferred application. Thus, users can communicate with vehicles in the same way they communicate with others in social situations, because the medium is the same and can be freely written. Vehicles can also be listed in the user's contact list just like people, making contact with vehicles easy. Overall, this facilitates communication with vehicles.

[0017] The invention also includes embodiments that produce additional advantages.

[0018] One implementation specifies that messages are provided as text messages and / or voice messages and / or video messages. In other words, messages sent from a mobile terminal device to a fleet server via a social media application can be sent as text messages and / or voice messages. Therefore, an interpreter can, for example, analyze the text of a text message or the audio signal of a voice message to determine if a vehicle function call has occurred. Alternatively, video can also be sent as a message, wherein the video, especially the audio track of the video, can be analyzed by an interpreter. With this implementation, communication with the vehicle can be performed using classic social media applications, which is particularly simple and intuitive for the user.

[0019] Another implementation specifies that the response message also includes an adjustment query for adjusting the vehicle parameters, based on the obtained vehicle parameters. The fleet server anticipates a response via a social media application. If the adjustment intent is deciphered from the response through an interpreter, the fleet server sends a vehicle function call to the vehicle to adjust the vehicle parameters. In other words, not only can vehicle parameters be sent as a response message to the mobile terminal device, but an adjustment query regarding whether the vehicle parameters should be changed can also be sent. For example, if the vehicle parameters are outside a preset standard range, the adjustment query can be related to the obtained vehicle parameters. Therefore, vehicle parameters could include, for example, the temperature present in the vehicle. If the temperature is below or above a preset threshold, the adjustment query could be, for example, whether the heating and / or air conditioning equipment should be activated. Subsequently, a response is awaited, specifically within a preset time, i.e., whether adjustment should be performed. For example, after sending the adjustment query to the mobile terminal device, a five-minute wait can be made to determine whether confirmation is received. If confirmation is received, the fleet server can generate a vehicle function call and send it to the vehicle, thereby adjusting the vehicle parameters accordingly. This implementation method offers the advantage that, because vehicle functions are controlled via a conversation through a social media application, it allows for intuitive and simple querying and control of the vehicle, particularly its functions.

[0020] Preferably, the response messages from the fleet server are generated by a chatbot. The chatbot is preferably part of a functional program on the fleet server, which can translate vehicle function calls into control commands for the motor vehicle and / or obtain vehicle parameters from the motor vehicle. A chatbot is a text-based dialogue system that can evaluate and autonomously create text input and text output, mimicking human behavior in a human-like manner. This results in the motor vehicle being viewed less as a technical object and more as a person, leading to a closer connection between the user and the vehicle. Furthermore, it can facilitate communication with the motor vehicle.

[0021] Particularly preferably, the interpreter includes a self-learning algorithm that identifies the semantics of messages from the mobile terminal device to determine vehicle function calls. In other words, the interpreter can be based on artificial intelligence, which can learn from the user's messages while chatting and thus adapt to the user's language and writing style. Therefore, vehicle function requests can be better identified from messages. Preferably, the self-learning algorithm can also be executed on the fleet server's function program and identify user behavior patterns, thereby automatically creating adjustment queries for the user's mobile terminal device. Thus, for example, it can be known through the self-learning algorithm that the user always uses the vehicle at a specific time in the morning. For example, an adjustment query, such as whether the parking heater should be activated, can be generated and sent to the user's mobile terminal device at a time before the vehicle is used.

[0022] Another implementation specifies that a fleet server determines which vehicle functions are provided by the motor vehicle. If a non-existent vehicle function is identified as a vehicle function call, the faulty fleet server sends an error message to the mobile terminal device. In other words, for example, after creating a social media profile for a motor vehicle, it can be determined which vehicle functions are present in the motor vehicle. For example, a motor vehicle may have an internal combustion engine, and vehicle function calls regarding battery capacity can be responded to accordingly using error messages. To enable the fleet server to determine which vehicle functions are present in the motor vehicle, the vehicle equipment can be queried from a database of storable equipment, for example, based on the vehicle identification number. Alternatively, the fleet server can also drive the motor vehicle's central controller, which can inform the vehicle of which vehicle functions are present. This implementation provides the advantage that data transmission to the motor vehicle can be limited because the fleet server does not request non-existent vehicle functions.

[0023] Another implementation specifies that the method further includes the following steps before step b): creating a social media profile for the vehicle and associating the social media profile with a social media interface of a fleet server, wherein, when associating the social media profile with the social media interface, an authorization request is sent to the vehicle, and the association is performed only if the vehicle approves the authorization request. In other words, to verify that the creator of the social media profile is the owner of the vehicle, an authorization request can be sent to the vehicle, for example, to the vehicle's infotainment system. Only after the authorization request is confirmed can the social media profile be associated with the social media interface that allows access to the vehicle. This provides the advantage of improved security.

[0024] Another implementation specifies that the fleet server provides social media interfaces from multiple different vendors for the vehicles. Therefore, the fleet server and vehicles are not limited to a single vendor's social media application; rather, the fleet server can have interfaces for multiple different vendors. Thus, multiple individuals sharing vehicles but using different social media applications can also utilize the functionality provided by this method.

[0025] Preferably, when a message is received in step b), it is also checked whether the sender of the message has communication authorization, wherein subsequent steps of the method are executed only if the sender is authorized. In other words, the mobile terminal device used to communicate with the vehicle can be connected or disconnected. Therefore, multiple individuals using the same social media application and connected to the vehicle's social media profile can, for example, send messages to the vehicle's social media profile, wherein only those messages that are authorized are further processed. Alternatively, in the case of a message from an unauthorized user, an authorization request can be generated through the fleet server, which can be sent to authorized users, especially the vehicle owner. Authorized users can then grant or deny permissions to communicate with the vehicle. This provides the advantage of improved security on the one hand, and the functionality of the method for multiple individuals using the vehicle and the same social media application on the other.

[0026] Another aspect of the invention relates to a system having at least one mobile terminal device, at least one motor vehicle, and a fleet server, wherein the fleet server is designed to perform the method according to one of the foregoing embodiments. The motor vehicle is preferably designed as a motor vehicle, particularly a passenger car or truck, or as a bus or motorcycle. This aspect of the invention yields the same advantages and possibilities of variation as in the method.

[0027] The invention also includes a control device for the system. The control device may have a data processing apparatus or a processor device for performing embodiments of the method according to the invention. The processor device may therefore include at least one microprocessor and / or at least one microcontroller and / or at least one FPGA (Field Programmable Gate Array) and / or at least one DSP (Digital Signal Processor). Furthermore, the processor device may have program code designed to perform embodiments of the method according to the invention when implemented by the processor device. The program code may be stored in the data memory of the processor device.

[0028] The present invention also includes improvements to the system according to the invention, which have features already described in conjunction with improvements to the method according to the invention. For this reason, corresponding improvements to the system according to the invention will not be described here.

[0029] The present invention also includes combinations of features of the described embodiments. Therefore, the present invention also includes implementations having combinations of features of multiple embodiments described, unless these embodiments are described in a contradictory manner. Attached Figure Description

[0030] Embodiments of the present invention are described below. Therefore:

[0031] Figure 1 An illustrative system for communicating with a motor vehicle, according to an exemplary embodiment, is shown;

[0032] Figure 2 A schematic flowchart of a method for communicating with a motor vehicle according to an exemplary embodiment is shown. Detailed Implementation

[0033] The embodiments explained below are preferred embodiments of the present invention. In the embodiments, the components described in the embodiments represent individual, considered independent features of the invention, which also independently improve the invention. Therefore, this disclosure is also intended to include combinations different from the combinations of features shown in the embodiments. Furthermore, the described embodiments may be supplemented by additional features among the already described features of the invention.

[0034] In the accompanying drawings, the same reference numerals denote elements that have the same function.

[0035] exist Figure 1 The diagram illustrates an illustrative system 1 for communicating with a motor vehicle 2 according to an exemplary embodiment. In addition to the motor vehicle 2, system 1 may have at least one mobile terminal device 3, 4, 5, 6 and a fleet server 7. Alternatively, multiple servers, particularly a computer cloud, may be used, where different functional steps can be distributed across various servers, for example.

[0036] Mobile terminal devices 3, 4, 5, and 6 can be designed as smartphones and / or tablets, respectively, where different social media applications can run on mobile terminal devices 3, 4, 5, and 6. Therefore, mobile terminal device 3 can, for example, have a different social media application than mobile terminal device 4. Social media interfaces 8, 9, 10, and 11 for the respective social media applications are preferably provided on the fleet server 7.

[0037] To communicate with vehicle 2, for example, to query sensor values ​​or control vehicle functions, it can be stipulated that a social media profile has been created for the vehicle on behalf of a social media application provider. A message can then be sent, for example, from mobile terminal device 3 to the social media profile of vehicle 2, wherein the message is received by the social media interface 8 of fleet server 7, which is adapted to the social media application of mobile terminal device 3. The received message can then be analyzed by interpreter 12, wherein the semantics of the message are interpreted to determine vehicle function calls. Here, a vehicle function call can be a command for querying sensor values ​​or for controlling another vehicle function, wherein, however, the command does not necessarily need to be explicitly stated in the message. The message can be provided, for example, as a text message and / or a voice message, wherein, preferably based on a self-learning algorithm, interpreter 12 can analyze the grammar and / or syntax of the message, i.e., whether a command for querying sensor values ​​can be extracted from the message. That is, interpreter 12 determines the intent behind the message.

[0038] If the vehicle function call is identified from the received message by the interpreter 12, the function program 13 of the fleet server 7 can then convert the vehicle function call into a control signal, which includes the logic portion for interacting with the vehicle 2. In other words, the function program 13 can convert the identified vehicle function call into a control signal, thereby controlling the functions of the vehicle 2, especially the sensors of the vehicle 2. Subsequently, the control signal can be sent to the corresponding vehicle 2 via the vehicle interface 14. Preferably, the vehicle parameters in the vehicle can then be determined or adjusted, for example, by triggering the sensors of the vehicle 2 with the control signal and measuring the sensor values. The vehicle parameters thus measured can then be transmitted to the fleet server 7, whereby the fleet server 7 receives the vehicle parameters via the vehicle interface 14.

[0039] In the fleet server 7, the functional program 13 can generate a response message, for example, using the received vehicle parameters. This response message can be sent back to the mobile terminal device 3 via a social media application. To generate the response message, a chatbot is preferably used, which adds the vehicle parameters to the text, thus creating the impression that the response message comes from a real person. Preferably, it can also be specified that the response message includes, depending on the queried vehicle parameters, an adjustment query for adjusting the vehicle parameters. This means that the vehicle parameters can not only be queried but also adjusted. For this purpose, the fleet server 7 can, for example, wait for a reply within a preset time after sending the response message; this reply can be interpreted as an intention to adjust the vehicle parameters.

[0040] For example, a user can write to vehicle 2 via a social media application on their mobile device 3: “How warm is it today?”. This message is received by social media interfaces 8, 9, 10, and 11 of fleet server 7, and interpreter 12 interprets the message content. For example, the content can be identified as a vehicle function call with the content “Query outside temperature”. This message can be forwarded to function program 13 of fleet server 7. Function program 13 can then access vehicle 2 via vehicle interface 14 and query the vehicle parameter for the outside temperature. Based on the received value, such as 31 degrees Celsius, function program 13 determines that the air conditioning function of vehicle 2 can be provided to the user. An additional adjustment query can be used, for example, using the text message “The outside temperature is 31 degrees Celsius. Should I turn on the air conditioning?” to create a response message. This response message can then be sent back to mobile device 3 via the social media application, and a reply can be awaited. For example, if the user replies “Of course!”, the message can then be read and interpreted again using the previously described value, where interpreter 12 identifies permission for the adjustment query from the message. Function program 13 can then activate the air conditioning function of vehicle 2 via vehicle interface 14. Therefore, users can communicate or chat with their vehicles in common ways without having to learn fixed commands.

[0041] exist Figure 2 The diagram illustrates a schematic method flowchart for communicating with a motor vehicle 2 according to an exemplary embodiment. The method shown here can preferably be performed by a fleet server 7. In step S1, at least one social media interface 8 can be provided for communication with the motor vehicle. Furthermore, it is preferable that social media materials be provided to the motor vehicle 2, for example, through a supplier of a social media application. Communication is provided via the social media interface 8 via a social media application, preferably from a third-party supplier, and via text and / or voice messages.

[0042] In step S2, the message from mobile terminal device 3 is received via the social media interface 8 of fleet server 7 through the social media application. Subsequently, in step S3, a vehicle function call can be determined from the received message by interpreter 12, whereby the semantics of the message are interpreted by interpreter 12 to determine the vehicle function call. If such a vehicle function call is determined from the received message, then in step S4, the vehicle function call can be executed in vehicle 2. For example, vehicle 2 can query or adjust at least one vehicle parameter belonging to the determined vehicle function call. Finally, in step S5, if fleet server 7 obtains the vehicle parameters of vehicle 2 as a response to the vehicle function call, then a response message can be sent from fleet server 7 to mobile terminal device 3 by means of the social media application, wherein the response message is generated based on the obtained vehicle parameters and, for example, inserted into a text message by a chatbot. Preferably, steps S2 to S5 can be repeated, i.e., each time a message is received by fleet server 7.

[0043] In summary, these examples demonstrate how social media profiles can be provided for motor vehicles using this invention.
