Description

The invention relates to a method for operating a graphical user interface of a means of transportation, a means of transportation and a cloud server.

Many automotive suppliers and manufacturers currently offer an ever broader range of digital services with various usage scenarios in vehicles and related business models. The classic vehicle range is to be supplemented by various digital services (e.g. Connected Drive Services) in order to generate new sales potential. For this purpose, appropriate displays and the associated “head unit” are installed in the vehicles. The displays and head units are regularly brought to the market every 3 to 5 years with improved hardware equipment. Each generation of the head units is installed in different vehicle derivatives for about 8 years. The digital services run on this head unit, the head unit containing a graphical user interface. The long dwell times (approx. 8 years) of the hardware in the automobile and the long lifespan (approx. 15 years) of automobiles thus prevent keeping pace with the increasingly demanding graphic requirements of digital services. As a result, the performance of the hardware is a limiting factor that prevents the updated digital services from being executed. Customer expectations for digital services are largely defined by the consumer electronics industry. Performance increases of 56% per annum over the past 10 years have been common in this industry. The latest digital services or apps take advantage of this increasing performance. However, the performance of outdated graphical user interfaces, which are installed in many vehicles, cannot keep pace. Due to the integration in the vehicle, it is also difficult to keep the software up to date.

US 2015/0052447 A1 discloses a system and a method for coupling a display to a automotive display, wherein the graphic contents of the automotive display are displayed on a remote diagnostic interface.

WO 2014/085093 A1 discloses processing audio files through a cloud server. The processed audio files are then sent to user terminals. This is also possible when the end user is in a vehicle.

In addition, a system is known under the name “GeForce NOW” in which graphics of a computer game are rendered on a cloud server and data records which represent these rendered graphics are sent to a desktop PC and / or a MacBook. A computer game that places high graphic demands on the hardware can also be played essentially without any time delays, even when using relatively poorly performing hardware.

It is therefore an object of the present invention to alleviate the disadvantages of the prior art and to enable the implementation of sophisticated functions on a relatively underperforming hardware of a means of transportation.

The object is achieved according to the invention by the respective subject matter of the independent claims. According to a first aspect, the present invention relates to a method for operating a head unit, in particular a graphical user interface of a means of transportation. In particular, a “head unit” is understood to mean a system of the means of transportation comprising an evaluation unit (in particular a CPU and / or a microcontroller) and its periphery, in particular comprising a graphic user interface connected therewith. As means of transportation in the sense of the invention come e.g. Automobiles, in particular cars and / or trucks and / or planes and / or ships and / or motorcycles. A head-up display (HUD) and / or a central information display (CID) and / or a combination instrument are particularly suitable as the graphical user interface of a means of transportation. Furthermore, the term “graphical user interface of a means of transportation” is understood to mean components that are permanently, electrically and information technology permanently installed in the means of transportation, in contrast to a smartphone and / or a laptop.

In a first step of the method according to the invention, a first graphical content, which is provided for the graphical user interface, is generated on a cloud server. Additionally or alternatively, an arithmetic operation can be carried out for the head unit of the means of transportation. Computing operations are understood to mean, in particular, in addition to the creation of graphic content, EDP algorithms which require a relatively high processor performance. For example, the arithmetic operation can include generating artificial intelligence. In particular, an algorithm for autonomous driving comes into question here. The cloud server is outside the means of transportation. In the present case, a “cloud server” is understood to mean an external computer which provides computing power for the means of transportation. In other words, creating graphic content for the graphic User interface and / or performing a computing operation for the head unit of the means of transportation externalized or outsourced. The first graphic content can include, for example, a video and / or a context menu and / or app graphics. The generation and / or implementation can take place, for example, via an evaluation unit of the cloud server. In particular, a CPU and / or a microprocessor can be used as the evaluation unit. In a further step, a first data record is sent to the means of transport, which represents the first graphic content for the graphic user interface and / or the (in other words: the computing operation completed with the evaluation unit of the cloud server) for the head unit ,

The transmission can take place, for example, via any wireless communication between the cloud server and the means of transportation. In a further step, the first graphical content is displayed on the graphical user interface of the means of transportation and / or the performed arithmetic operation, which originates, for example, from a backend, is called up on the head unit as a function of the first data record. In other words, a complex task that requires an increased level of computing power in relation to the performance of the hardware of the means of transportation is carried out on a cloud server. A resulting data record, which represents graphical content and / or the computing operation for the head unit or the graphical user interface of the means of transportation, only has to be called up on the graphical user interface of the means of transportation or by a head unit of the means of transportation, without complex IT Algorithms for the creation of graphic content, whereby these computer algorithms have already been carried out on the cloud server, are required.

This means that there is always the possibility of displaying current digital services and / or apps on every means of transportation, which has a graphical user interface in the sense of the present invention, regardless of the age of the means of transportation, since the calculation of complex EDP algorithms (such as rendering graphics) ) takes place on the cloud server. In addition, digital services can be provided without the need for additional apps to be installed on the means of transportation, for example. In particular, only a streaming client is required here.

It is also advantageous that supposedly outdated hardware can keep pace with the development of complex graphic content and / or complex arithmetic operations by means of the inventive method described above without having to carry out a hardware upgrade in the means of transportation. This has the advantage, both for vehicles that are in circulation and for vehicles that will be put on the market in the future, that a minimum amount of hardware requirements is sufficient to display relatively complex graphic content, which leads to cost savings. The minimum level of hardware requirements is in particular support of the streaming client. In addition, the timeliness of the electronic service is ensured by the method according to the invention.

The dependent claims contain advantageous developments of the method according to the invention.

In an advantageous development, in a further step, user interaction with a predefined control element of the graphical user interface is determined within the means of transportation. In the present case, a gesture that is carried out either in contact with the graphical user interface or freely in the room is considered as user interaction. Such gestures include, in particular, tap gestures and / or swipe gestures and / or pinch gestures and / or spread gestures and / or multifinger gestures. Gestures that are carried out while touching the graphical user interface are, in particular, gestures that are carried out as interaction with a touch display and / or with hardware buttons of the means of transportation that are associated with the graphical user interface. The aforementioned hardware buttons and / or hardware controllers are particularly suitable as predefined control elements. Furthermore, a predefined control element can comprise, for example, a graphic object which is shown on a touch display.

In a further step of an advantageous development of the method according to the invention, a data record representing the user interaction is sent to a cloud server. The transmission can take place via any wireless communication between cloud server and means of transportation. A data record representing the user interaction can be, for example, a request to a cloud server to carry out a process, such as rendering a graphic. In a further step, a second graphical content for the graphical user interface is updated on the cloud server. For example, if the request concerns rendering a graphic, the refresh may involve rendering a graphic to be displayed next. This can be the case, for example, if a touch display is activated by actuating a soft key, that is to say a special graphic object next image is to be called, which image is then rendered on the cloud server.

In a further advantageous embodiment of the method according to the invention, a second data record representing a second graphical content for the graphical user interface is sent from the cloud server to the means of transportation. In this way, the computing power required for updating the second graphic content is provided on the cloud server. The next step is to display the updated second graphical content on the graphical user interface as a function of this second data record. The data record can, for example, be a fully rendered graphics package that can be sent to the means of transportation via wireless communication. In this way, the second graphical content of the graphical user interface of the means of transportation can be easily updated without high computing power of an evaluation unit, e.g. a CPU and / or a microcontroller, the means of transportation.

According to a further advantageous embodiment of the method according to the invention, the predefined control element of the graphical user interface is assigned to a vehicle function and / or social media content and / or multimedia content and / or a video stream. A vehicle function can include, for example, an air conditioning system control and / or an adjustment of the seating position and / or a heater. The predefined control element can comprise, for example, a hardware button or a graphic object, for example a soft key on a touch display. In particular, in the case of a video stream, it is possible to interact with an object, which is shown as graphic content or soft key on a display, in order to start or stop the video stream. For example, the object can include a soft key with the inscription "start video stream".

Thus, via the predefined control element, a request regarding the processing of certain EDP algorithms, such as the rendering and / or buffering of a video stream, can be sent to a cloud server. In response, this cloud server generates the graphic content required for the video stream.

According to a further advantageous embodiment, the method according to the invention comprises the triggering of a means of transportation function assigned to the predefined control element of the graphical user interface. For this purpose, for example, a temperature control for the interior of the means of transportation can be initiated via a predefined control element. In response to this, an inquiry regarding a data record representing an inquiry regarding the temperature change can be sent to an external cloud server. This cloud server can, for example, process the EDP algorithm that is necessary to initiate the temperature control of the means of transportation. The cloud server can then send a data record representing the triggering of the function back to the means of transportation. In response to this, the function, for example the setting of a target temperature, is carried out automatically in the means of transportation.

The method can further advantageously include the steps of receiving position data of a user's contact with the graphical user interface and sending a data record representing the position data to the cloud server. Here, the graphical user interface can only be a touch-sensitive two-dimensional sensor matrix, e.g. on a touch display. The position data can be generated, for example, in response to a typing gesture on the graphical user interface. In particular, the x, y coordinates of the position to which the user made the typing gesture are recorded. As a result, a data record that represents this position data is sent to the cloud server. Here, for example, the position data on the cloud server can be associated with a predefined control element, which is located at this position data. Furthermore, the EDP algorithm associated with the actuation of this predefined control element can be triggered and executed on the cloud server. In a next step, a data record representing the IT algorithms associated with the position data can thus be sent back to the means of transportation. In other words, depending on a user input, only the position at which the user input was received must be known to the means of transportation. The request, which for example triggered a process, e.g. rendering graphics associated and the computing power required to perform this process are provided on an external cloud server. The requirement for the computing power of an evaluation unit of the means of transportation is further reduced.

In a further embodiment of the method according to the invention, a remote desktop connection can be established between the means of transportation and the cloud server. In particular, all application programs associated with the graphical user interface of the means of transportation are opened rendered, processed and operated by an external cloud server. The graphical user interface of the means of transportation now primarily has the function of displaying graphical content and / or receiving user input, the other processes essentially taking place on the remote server, that is to say the cloud server. In this way, in particular a high degree of relief of the computing power requirements with regard to the evaluation units, in particular the CPU and / or the microcontroller, of the means of transportation can be achieved by essentially relocating the processes to a cloud server. This has the advantage that these intended applications are retrofitted and used independently of the hardware even during the development of the means of transportation.

In a further advantageous embodiment of the method according to the invention, the first and / or second graphic contents comprise a video and / or a context menu and / or app graphics. In other words, the first and / or second graphic contents can comprise a static image and / or a dynamic image sequence. For example, a context menu can contain predefined operating elements which are associated with functions of the means of transportation, as described above. Even in the case of a video, inquiries about complex rendering processes, which may not be able to be implemented with the hardware of the means of transportation, can be sent to the cloud server, which performs these complex renderings, and data records, e.g. represent a video to which means of transportation returns. In particular, app graphics, which also require complex graphic renderings, can be rendered externally before data records representing these renderings are sent back to the means of transportation for simple display.

The method according to the invention can furthermore advantageously comprise the steps of analyzing an available bandwidth and reducing or increasing a request for the first and / or second graphic contents as a function of the available bandwidth. Available bandwidth can primarily depend on connectivity to an external cloud server. For example, the connectivity may deteriorate due to a distance from the cloud server and / or driving through a tunnel and / or a dead zone and / or other wireless connection problems. This can be determined, for example, using a satellite-based location procedure. In addition, the Quality of Service (QoS) card is also conceivable, which contains information, what quality (e.g. of the mobile network) can be expected at the respective location. In the event of a deterioration in the available bandwidth, in particular a message representing a performance requirement in the generation of the first and / or second graphic content, which is communicated to the cloud server, can be reduced. For example, fewer “frames per second” and / or a lower resolution and / or a lower number of colors and / or an exclusive gray tone display of first and / or second graphic content compared to a predefined graphic reference, which represents normal performance with an average available bandwidth , Can be requested. In this way, the method according to the invention can ensure the generation of graphic content on the cloud server and the continuous communication between the means of transportation and the cloud server. Should the available bandwidth increase again, these performance requirements can be increased again. In this way, depending on a connectivity between the vehicle and the cloud server, an extended possibility of maintaining the externalization and the reception of the graphic content can be maintained within a wide range of an available bandwidth. For example, the user of the means of transportation can also switch between a basic visualization or a basic calculation, which places reduced demands on the hardware, and an increased requirement, manually, locally and continuously, within the means of transportation.

According to a further advantageous embodiment of the method according to the invention, the computing operation can include creating an audio file and / or generating artificial intelligence, for example an algorithm for autonomous driving. In this case, complex arithmetic operations which are too high, in particular for the hardware requirements of the head unit of the means of transportation, are advantageously externalized.

The aspects according to the invention mentioned below correspond to the features, effects and advantages described above, as it were. Therefore, to avoid repetition, the list or explanation is omitted.

According to a second aspect, the present invention relates to a means of transportation comprising a graphical user interface, which is set up to receive user interaction with an operating element of the graphical user interface and / or to display first and / or second graphical contents. Furthermore, the means of transportation has a transmission unit which is set up to represent a user operation and / or a computing operation for the head unit representing a request Send data record to a cloud server. The transmission unit can comprise any transmission unit suitable for wireless communication, as is known to the person skilled in the art. Furthermore, the means of transportation comprises a receiving unit, which is set up to receive a record representing updated first and / or second graphical content for the graphical user interface and / or the computing operation of the head unit carried out by the cloud server. Here, too, any receiver unit that is suitable for wireless communication with a cloud server can be used.

According to a third aspect, the present invention relates to a cloud server comprising a receiving unit which is set up to receive from a means of transport a data record representing user interaction and / or a computing operation representing the head unit. Any receiving unit for wireless communication of graphical data can be used here. Furthermore, the cloud server comprises an evaluation unit which is set up to generate and / or carry out first and / or second graphical contents of a first graphical user interface with regard to the data record representing the user interaction and / or the computing operation for the head unit. Furthermore, the cloud server has a transmission unit which is set up to send a graphic content of the graphic user interface generated by the evaluation unit of the cloud server and / or the first data record representing the computing operation performed for the head unit to a means of transportation.

A plurality of cloud servers can thus be arranged as decentralized units. For example, such a decentralized unit can be designed to carry out the method according to the first aspect within a certain radius in cooperation with the means of transportation according to the second aspect of the invention. A network can be created by means of several of these decentralized units, as a result of which the means of transport can interact with the cloud servers within a large spatial area. With such a decentralized positioning of the cloud server, latency times can be kept so low that, especially in 4G / 5G networks, a latency period that results from the interaction between the means of transport and the cloud server is barely perceptible to the user. For example, ongoing calculations can also migrate between different decentralized cloud servers. This means that a decentralized cloud server can, for example, pass on an ongoing calculation to another decentralized cloud server if the means of transport gets into the area of this additional cloud server. A territorial range of a decentralized cloud server can in particular include a city area and / or a federal state and / or a state and / or a continent. In particular, a continental reach, especially for Europe, can be achieved using the GeForce Now technology discussed above. In addition to decentralized cloud servers, central cloud servers, which include, for example, an AWS and / or Azure setup, are also possible.

In a first step 100 the first graphic content is generated 11 which is for the graphical user interface 3 of the means of transportation 10 . 20 is provided on a cloud server 2 , The creation may include rendering a video, for example. In a second step 200 the first data record is sent 4 to the means of transportation 10 . 20 , This first record 4 can for example via a receiving unit 14 of the means of transportation 10 . 20 be received. The first record 4 represents the first graphic content 11 , By having the first record 4 already on the cloud server 2 was generated, an additional arithmetic operation can be used to generate the first graphic content 11 a means of transportation 10 . 20 to be dispensed with. This is the third step 300 the presentation of the first graphic content 11 which can be, for example, a video, on the graphical user interface 3 of the means of transportation 10 . 20 depending on this first record 4 , If the user 1 an input on the graphical user interface 3 which, for example, can be a central information display, is carried out in a fourth step 400 a user interaction is determined. Interaction by the user 1 This is done with a predefined control element 5 the graphical user interface 3 within the means of transportation 10 . 20 , Such an interaction can be a typing gesture, for example on a predefined control element 5 , which can be a button on a display, for example.
