Description

State of the art

[0001] The present invention relates to a method for transmitting route data when a vehicle travels through a geographical area in which a mobile radio connection of a mobile data transmission device to an external network exists, to an associated mobile data transmission device and to a corresponding computer program product.

[0002] There are currently numerous applications for smartphones and systems installed in vehicles that send or request data (in the background) via mobile communications. Examples include navigation applications that send Floating Car Data (FCD) or receive traffic information via mobile communications. Furthermore, various developments and research projects are working on so-called car-to-infrastructure functions. Some of these, such as a traffic jam warning, send data via mobile communications to a central unit in potentially dangerous situations, which in turn forwards warning information to a group of relevant vehicles via mobile communications or other communication technologies.

[0003] In many cases, sending data via mobile communications in a roaming network is significantly more expensive than using the home network. If the general sending and receiving of data were to be omitted in the roaming network due to the higher costs, no data would be sent or received even if this were highly relevant to the driver in a given situation. This would be the case if the driver, for example, had accepted the costs incurred to send a warning to following traffic, as in the case of a traffic jam.

[0004] The current state of the art generally provides the option to disable the general reception and transmission of data. Furthermore, mobile phones such as the Apple iPhone offer the option to enable general reception and transmission and to block the transmission of push notifications from individual applications.

[0005] US 2011 019 57 00 A1 shows the configuration of a mobile wireless communication device using a bearer service configuration profile selected from a set of stored carrier configuration profiles.

[0006] US 2005 / 0261829 A1 discloses a system for navigation assistance provided by an external vehicle service provider. A request for navigation information is sent from a vehicle system to a service provider, and the service provider transmits the navigation information back to the vehicle via a mobile phone connection. The corresponding information is displayed in the vehicle. The transmitted data depends, among other things, on whether the mobile phone is in its home network and the user preferences selected.

[0007] From DE 10 2009 031 275 A1 a navigation arrangement for a motor vehicle is known, wherein a selection of data packets intended for transmission into the motor vehicle or their sequence is made depending on the resolution of the display, the location of the motor vehicle, an assumed route of the vehicle or the bandwidth of a communication connection intended for the transmission. Disclosure of the invention

[0008] Against this background, the present invention presents a method, a mobile data transmission device that uses this method, and finally a corresponding computer program product according to the main claims. Advantageous embodiments emerge from the respective subclaims and the following description.

[0009] The present invention provides a method for transmitting route data when a vehicle travels through a geographical area in which a mobile radio connection of a mobile data transmission device to a foreign network exists, wherein the foreign network differs from a home network to which the mobile data transmission device is assigned, and wherein the method comprises the following steps: - Reading in position information which includes information that a mobile radio connection exists between the mobile data transmission device and the external network and / or that there is no direct mobile radio connection between the home network and the mobile data transmission device; - detecting setting information of the mobile data transmission device, wherein the setting information contains information about whether route data and / or what type of route data may be sent and / or received via an interface of the mobile data transmission device; and - Outputting or transmitting the route data via the interface of the mobile data transmission device in response to the position information and the setting information.

[0010] The present invention further provides a mobile data transmission device or apparatus designed to carry out or implement the steps of the method according to the invention in corresponding devices. This embodiment of the invention in the form of an apparatus or mobile data transmission device also allows the object underlying the invention to be achieved quickly and efficiently.

[0011] In this case, a device or a mobile data transmission device can be understood as an electrical device that processes sensor signals and outputs control and / or data signals depending on them. The device can have an interface that can be implemented in hardware and / or software. In a hardware implementation, the interfaces can, for example, be part of a so-called system ASIC, which contains a wide variety of functions of the device. However, it is also possible for the interfaces to be separate integrated circuits or to consist at least partially of discrete components. In a software implementation, the interfaces can be software modules that are present, for example, on a microcontroller alongside other software modules.

[0012] Also advantageous is a computer program product with program code that can be stored on a machine-readable medium such as a semiconductor memory, a hard disk memory or an optical memory and is used to carry out or control steps of the method according to one of the embodiments described above when the program product is executed on a computer, a device or the mobile data transmission device.

[0013] Route data can be understood as data that includes information about traffic events, road surface conditions, safety-critical vehicle conditions, weather events or similar information that is relevant for driving safety and efficiency for other vehicles in the vicinity of the vehicle. A mobile radio connection can be understood as an existing direct connection or a direct connection that is currently being established between two data transmission devices. In this case, either both data transmission devices can be mobile, or one of the data transmission devices can be operated stationary at a fixed location while the other data transmission device is mobile. A third-party network can be understood as a data transmission network that is operated, for example, by an operator with whom a user of the mobile data transmission device has not concluded a usage contract.A home network, on the other hand, can be understood as a data transmission network operated by an operator with whom a user of the mobile data transmission device has concluded a user agreement. Position information can be understood as information about the current position, which, for example, signals to the mobile data transmission device that there is no or should not be a mobile radio connection between the mobile data transmission device and a receiver and / or transmitter in the home network, but that only a mobile radio connection between the mobile data transmission device and a receiver and / or transmitter in the external network exists or can exist.Setting information can be understood, for example, as the parameter that enables a distinction to be made between first route data that may be sent via the interface of the mobile data transmission device and second route data that may not be sent via the interface of the mobile data transmission device. A type of route data can be understood, for example, as a class of route data that contains information about an aspect of the vehicle's journey. For example, such a class of route data can contain information about traffic conditions, for example, about the occurrence of a traffic jam at a specific geographical location at or near which the vehicle is currently located.Another class of route data may, for example, contain information about road surface conditions to provide other vehicles in the vicinity of the vehicle's current geographical position with an indication of a potentially existing hazard related to a specific road surface characteristic. For example, such a road surface characteristic could be increased slipperiness due to ice or wet conditions.

[0014] The present invention is based on the realization that it is now possible to differentiate between which type of route data or whether route data should be transmitted at all. This makes it possible to decide on the transmission of route data per se or to distinguish between route data to be transmitted and route data not to be transmitted based on one or more criteria. By using the position information, which provides information about the existence of the mobile radio connection to the external network and not to the home network, and the setting information for detecting and distinguishing between the route data to be transmitted and those not to be transmitted, it is possible on the one hand to achieve increased security and on the other hand to avoid an excessive increase in the expected mobile radio costs.The increased safety gain is achieved by transmitting route data to other vehicles, providing them with an indication of the traffic and safety situation at the vehicle's current geographical position. Receiving journey data transmitted by other vehicles also allows the information contained in the vehicle data to be taken into account, allowing the processing of safety-relevant information about a geographical position that the vehicle may soon reach. In this way, for example, the driver can signal in a timely manner that an approaching traffic jam is about to end.

[0015] According to one embodiment of the present invention, a further step of receiving trip data via the interface of the mobile data transmission device may be provided, taking into account the position information and the setting information, wherein the trip data comprises at least one piece of information relating to the driving safety of the vehicle on a trip and / or at least one piece of information about a traffic situation and / or at least one piece of information about a road surface condition and / or at least one piece of information about a weather situation. Such an embodiment of the present invention offers the advantage that not only can the transmission of route data in the external network be reduced to the lowest possible level, but also that the retrieval of trip data can be reduced to the lowest possible level.This allows data transmission costs to be reduced, while still allowing data to be transmitted or received in certain situations that are particularly relevant to the driver of the vehicle.

[0016] A further advantageous embodiment of the present invention is one in which a step of generating the position information is provided before the reading step, wherein in the generating step the position information is generated by evaluating satellite navigation signals and / or by evaluating signaling data from the external network and / or the home network and / or by evaluating a network change signal manually entered by a user of the mobile data transmission device. A network change can be understood, for example, as a change from the home network to the external network or vice versa. Such an embodiment of the present invention offers the advantage that the position information can be obtained in a technically simple and cost-effective manner or that simple and thus cost-effective signaling of a network change is possible.

[0017] A particularly advantageous embodiment of the present invention is one in which, in the detection step, at least one piece of setting information is detected that represents a predetermined maximum amount of data that may be transmitted via the interface of the mobile data transmission device. Such an embodiment of the present invention offers the advantage of ensuring that no more than the predetermined maximum amount of data may be transmitted via the interface of the mobile data transmission device to units of the external network. This ensures that no unexpectedly high costs are generated for transmitting data in the external network.

[0018] According to a further embodiment of the present invention, price information about a price per transmitted data unit in the external network can be provided in the reading or capturing step, wherein in the outputting step the route data is output if a total price for transmitting the route data using the mobile radio connection to the external network does not exceed a predetermined cost threshold. A data unit can be understood as a data packet with a predefined amount of information. Such an embodiment of the present invention offers the advantage that, with different prices per transmission of a data unit in different external networks, it can still be ensured that a cost framework specified, for example, by the user of the mobile data transmission device is not exceeded even when route data is transmitted in different external networks.

[0019] Another advantageous embodiment of the present invention is one in which, in the detection step, setting information is detected which contains information that route data containing information about a traffic situation and / or a road surface condition and / or a weather situation may be sent and / or received by the mobile data transmission device. Such a traffic situation occurring in the vicinity of the vehicle can, for example, be the occurrence and detection of a traffic jam, an accident, or a traffic-related waiting time in front of an obstacle. Information about a road surface condition can, for example, be information that it is currently particularly smooth or slippery at a certain geographical location, or that the road surface has been removed, for example, and / or the road surface is covered with gravel.A weather situation can be understood, for example, as the occurrence of a bank of fog or a rain shower at a specific geographical location. Such an embodiment of the present invention offers the advantage that the setting information can be used to precisely select which of several possible types or classes of information in the route data should and / or may be transmitted via the interface of the mobile data transmission device.

[0020] In order to ensure the most flexible transmission of data, for example while the vehicle is moving, according to one embodiment of the present invention at least the steps of detecting and outputting can be repeated several times, wherein in the first step of detecting a first item of setting information is detected and the first step of outputting is carried out using the first item of setting information and wherein in the second step of detecting a second item of setting information which is different from the first item of setting information is detected and the second step of outputting is carried out using the second item of setting information, in particular wherein the change of the first item of setting information to the second item of setting information is based on a manual input by a user of the mobile data transmission device.Such an embodiment of the present invention offers the advantage that, for example, if the driver's or user's priorities for the route data to be transmitted change at different times of use of the mobile data transmission device, adaptation is also possible by simply changing the setting information. In this way, for example, at a first time of use, route data relating to traffic conditions can be transmitted using appropriate setting information. However, if the weather changes, the driver of the vehicle or a user of the mobile data transmission device can change the setting information such that the route data relating to the weather conditions is now transmitted primarily or exclusively via the interface.

[0021] According to another embodiment of the present invention, a further step of evaluating the route data can be provided, wherein the evaluation step provides the position information and / or the setting information that is read in during the reading step and / or that is acquired during the acquisition step. Such an embodiment of the present invention offers the advantage that, for example, certain route data are provided in advance with an identifier that ensures that the relevant route data are transmitted securely via the interface. For example, it would be conceivable to output emergency signals as route data if an accident occurs involving the host vehicle and to provide them with setting information that ensures that these emergency signal route data are also output via the interface of the mobile data transmission device.This can result in a significant increase in safety, as, for example, following vehicles that receive this emergency signal route data as journey data can be alerted to an accident-damaged vehicle at an early stage.

[0022] The invention is explained in more detail below with reference to the accompanying drawings. They show: Fig. 1 is a schematic representation of a vehicle with a mobile data transmission device according to an embodiment of the present invention, wherein an interface of the mobile data transmission device is in radio communication with a unit of a third-party network; Fig. 2 shows a block diagram of a mobile data transmission device according to an embodiment of the present invention; and Fig. 3 a flowchart of a method according to an embodiment of the present invention.

[0023] In the following description of preferred embodiments of the present invention, the same or similar reference numerals are used for the elements shown in the various figures and having a similar effect, whereby a repeated description of these elements is omitted.

[0024] Fig. 1 shows a schematic representation of a vehicle 100 with an information device 110 according to an exemplary embodiment of the present invention, wherein an interface 115 (equipped with an antenna) of a mobile data transmission device 110 is in radio connection 130 with a unit 135 of an external network 140. The external network 140 is operated by a different network operator than a mobile radio network, which is assigned to the mobile data transmission device 110 as the home network 145. Such an assignment of the mobile data transmission device 110 to the home network 145 can be understood, for example, as meaning that a user of the mobile data transmission device has a direct usage contract with the network operator of the home network 145, but not with the network operator of the external network 140.Typically, a roaming agreement exists between the network operator of the home network 145 and the network operator of the foreign network 140, so that the mobile data transmission device 110 can also establish a mobile radio connection 130 to units 135 of the mobile radio network of the foreign network 140 and transmit data via this mobile radio connection 130. However, this is usually associated with significantly higher data transmission costs than the costs for a similar data transmission between the mobile data transmission device 110 and units of the mobile radio network of the home network 145.In order to save costs as much as possible, a user of the mobile data transmission device 110, if they know their current position in an area that only allows a mobile radio connection to units of the operator of the external network 140, can completely forgo the transmission of data to units 135 of the mobile radio network of the external network 140 (also referred to simply as the external network 140 in this description for reasons of simplicity). However, for reasons of driving safety or increased driving comfort, it may be advantageous in certain situations to nevertheless transmit data relating to the driving status and / or information about the route traveled by the vehicle 100, or to read corresponding signals provided by other vehicles, which also relate to the driving status or information about the routes traveled by these vehicles, into the mobile data transmission device 110.In this case, the user of the mobile data transmission device 110 could see a predominant advantage in transmitting or receiving the data in question, even if this is associated with increased data transmission costs. For example, a user of the mobile data transmission device 110, which is installed in a vehicle 100 (or at least located in the vehicle) on a road 150 within the transmission / reception range of the external network 140, could output route data 160 to provide information about a geographical position of the end 155 of a traffic jam on the road 150. This route data 160 could then be output, for example, via the radio connection 130 to units 135 of the external network 140, which then also forwards the information of the route data 160 to another vehicle 165 via a mobile radio connection 130.In this additional vehicle 165, for example, the information from the route data 160 can then be evaluated and processed in a corresponding driver assistance system 170, so that, for example, an early warning of the driver of the additional vehicle 165 is possible before the end of the traffic jam at the geographical position 155. This can, for example, prevent a rear-end collision between the additional vehicle 165 and the vehicle 100 or at least significantly reduce the probability of such an accident. In this respect, the driver of the vehicle 100 may also have an interest in outputting corresponding route data 160 to units 135 of the external network 140, despite the increased costs, in order to derive their own benefit.

[0025] Additionally or alternatively, further information may of course also be included in the route data 160, representing, for example, road surface conditions (e.g., gravel or ice on the road) or a specific weather situation (e.g., fog or rain) at a specific location 155. In this case, too, the driver of the vehicle 100 containing the mobile data transmission device 110 may be interested in transmitting the route data 160, even if this entails higher costs than transmitting similar data in the home network 145.

[0026] Of course, a reverse scenario is also conceivable, in which the driver assistance system 170 of the further vehicle 165 transmits information corresponding to the route data 160, which can be read or captured by the mobile data transmission device 110, so that the driver of the vehicle 100 can expect an early indication of a special situation at certain points that may be on their route. For this purpose, the appropriate selection of the setting information can also ensure prioritization of the retrieval of corresponding information from a unit 135 of the external network 140, so that only predetermined data needs to be retrieved, but a constant data connection does not need to be maintained, and all (even irrelevant) data needs to be transmitted. In this way, the costs for using the external network 140 can be kept low even when retrieving data from the external network 140.

[0027] Fig. 2 shows a block diagram of a mobile data transmission device 110 according to an exemplary embodiment of the present invention. The mobile data transmission device 110 comprises, in particular, a device 210 for reading in and / or delivering a position signal 215, wherein this position signal provides an indication that the mobile data transmission device 110 is located within the transmission / reception range of the external network 140. For this purpose, an evaluation of satellite navigation signals, for example in the form of a GPS receiver, can be carried out in the device 210, which determines a current geographical location of the vehicle 100 or the mobile data transmission device 110 and compares it with a list to determine whether the mobile data transmission device 110 is within the transmission / reception range of the home network 145 or of an external network 140.Alternatively or additionally, an evaluation of signaling signals emitted by the units 135 of the external network 140 can of course also be carried out, and from this it can be recognized that the mobile data transmission device 110 is located within the transmission / reception range of the external network 140 and not within the transmission / reception range of the home network 145. It is also conceivable that a user of the mobile data transmission device 110 can manually press a button to signal to the device 210 that the mobile data transmission device is within the transmission / reception range of the external network 140.

[0028] Furthermore, the mobile data transmission device 110 comprises a device 220 for recognizing and / or providing setting information, via which it is possible to set whether route data 160 and / or which type of route data may be transmitted and / or received via the interface 115 of the mobile data transmission device 110. This device 220 for recognizing and / or providing the setting information can, for example, be a memory in which one or more parameters are stored that signal which type or class of information may be transmitted as route data 160 via the interface 115. Furthermore, it is conceivable that a user of the mobile data transmission device 110 can also change the setting information while the vehicle 100 is traveling in order to be able to react to a changed traffic situation.In this case, at a first point in time, a first item of setting information 225 could be used to enable the output of route data 160, whereas at a second subsequent point in time, the setting information is changed and / or stored by the device 220 for recognizing and / or providing a second item of setting information, and this second item of setting information 225 is then used to decide on the release or blocking of the route data 160 for transmission via the interface 150.

[0029] Furthermore, the mobile data transmission device 110 also comprises a device 230 for reading in or providing the vehicle data 235, which includes a large amount of information about the driving situation, such as the traffic situation, the road surface condition and / or weather behavior and / or the current geographical position of the vehicle 100, and which, however, do not necessarily need to be transmitted.

[0030] The mobile data transmission device 110 also comprises the Fig. 2, a device 240 for determining the route data 160 is provided. In this device 240 for determining the route data, this vehicle data 235 is analyzed taking into account the criteria from the position information and the setting information, and the route data 160 is generated that is actually to be transmitted or may be transmitted via the interface 115. For example, if the driver wishes to transmit only information about the traffic situation via the interface 115, the information about the road surface condition and / or the weather conditions can be extracted, which is then not contained in a data packet of the route data 160. Thus, in this case, only the information from the vehicle data 235 that contains the traffic situation (such as the occurrence of the end of a traffic jam at a specific position) will be contained in the route data 160.This ensures that the route data 160 only contains the data released for transmission via the interface 115 in accordance with the setting information 220.

[0031] In summary, it should be noted that the functionality described in the approach presented here is part of a mobile terminal 110 (e.g., mobile phone, personal navigation device, a system permanently installed in the vehicle) with a mobile radio interface 115, or can be subsequently installed on it. For example, the functionality mentioned can therefore be understood as an app, computer program, program routine, programmable hardware component, or similar element that is capable of executing or controlling specific steps. For the sake of simplicity, the term functionality is understood below to mean a method that runs in the unit 240 for providing and / or outputting the route data 160, since the algorithm implemented or programmed for the effectiveness of the functionality can be executed in this unit.How this is implemented in concrete terms can be left to the relevant specialist who is familiar with the modern tools for implementing such functions or functionalities in hardware or as a computer program.

[0032] If (e.g. when driving abroad) a mobile data connection 130 can only be established via a roaming network (as a foreign network 140), the functionality enables (possibly up to a certain maximum data volume) the selective reception and / or transmission of those data that are relevant for the driver or are assigned to an application relevant for the driver. An application can be understood, for example, as a unit in the mobile data transmission device 110 or a routine that supplies vehicle data for a driving scenario. In the example presented in the problem from the prior art presented at the beginning, data for driving safety-relevant applications such as the traffic jam end application (iea unit for detecting the end of a traffic jam and for transmitting the location of the end of a traffic jam) would be sent and / or received, whereas data for applications not relevant to driving safety, such as the humidity or temperature at the current location of the vehicle 100, would not be sent.

[0033] The functionality is based, for example, on the functional tasks described below: 5. The functionality 240 detects the change to a roaming network 140. This can occur, d. through direct, automatic detection of the network change by the mobile device, and / or e. by means of forward-looking predictive detection using a satellite-based positioning system or radio location, as well as a stored list, and / or f. by manual entry. 6. The functionality 240 also detects whether and which user settings 225 exist that generally permit the receiving and / or sending of data 160 in roaming networks 140, or permit them in certain situations, or generally prohibit them. In the case of restricted sending and / or receiving of data 160 via mobile radio 130, for example, further user-specific settings 225 are taken into account. The decision as to the extent to which data 160 can be received and / or sent in roaming networks 140 is made by the user, for example, when activating the functionality 240 and / or can be changed subsequently. As a result, the restricted sending / receiving of data 160 is situation-specific (e.g., adapted to potentially dangerous situations) and / or is permitted up to a certain data volume. 7. Furthermore, functionality 240 detects the category of information to be sent and / or received and / or its data size. The category of information is detected by: d. the information can be uniquely assigned to an application for which a category is known. For example, functionality 240 detects that a traffic jam application (implemented, for example, as a separate computer program or app on mobile data transmission device 110) wishes to send data 235. For the traffic jam application, the category "driving safety-relevant warning function" applies, for example. The user has assigned this category to the traffic jam application, or it has already been stored in the settings by software; and / or e. the information contains the category itself (e.g. self-identification by means of a text block that can be recognized by the functionality 240 or by means of an event code that can be clearly identified by the functionality 240), and / or f. the user assigns them manually. 8. After detecting the change to the roaming network 140, the functionality 240 checks the relevance of the data 160 to be sent and / or received. In doing so, it checks the settings 225 against the detected category of messages 235. If the result of the check is positive, data 235 or a part thereof is sent or received as route data 160; if the result of the check is negative, it is not sent or reception is prohibited.

[0034] Fig.3 shows a flowchart of a method 300 for transmitting route data when a vehicle travels through a geographical area in which a mobile radio connection from a mobile data transmission device to an external network exists, according to an exemplary embodiment of the present invention. The external network differs from a home network to which the mobile data transmission device is assigned. The method 300 comprises a step of reading in 310 a position information item, which includes information that a mobile radio connection exists between the mobile data transmission device and the external network and that no mobile radio connection exists between the home network and the mobile data transmission device.Furthermore, the method 300 comprises a step of acquiring 320 a piece of setting information of the mobile data transmission unit, wherein the setting information contains information about whether route data and / or what type of route data may be transmitted and / or received via an interface of the mobile data transmission device. Finally, the method comprises a step of outputting 330 the route data via the interface of the mobile data transmission device in response to the position information and the setting information.

Different exemplary embodiments can be combined with each other in their entirety or with regard to individual features. Furthermore, one exemplary embodiment can be supplemented by features of another exemplary embodiment.

[0036] Furthermore, method steps according to the invention can be repeated and carried out in a different order than that described.

[0037] If an embodiment comprises an “and / or” link between a first feature and a second feature, this is to be read as meaning that the embodiment according to one embodiment has both the first feature and the second feature and according to another embodiment has either only the first feature or only the second feature.
