Description

The invention relates to a motor vehicle with at least one mobile terminal. The mobile terminal is adapted to receive messages from at least one off-vehicle device, such as a mobile device. an Internet server, and / or another motor vehicle to receive and / or send to such. The mobile terminal may be, for example, an infotainment system or a navigation device. The invention also includes a method for controlling a data volume which the motor vehicle exchanges with the at least one vehicle-external device and / or the other motor vehicle when the at least one mobile terminal is active.

Motor vehicles today are networked with other motor vehicles and with other devices of their environment via communication networks by means of radio links. As soon as a motor vehicle has established such a communication connection, a data exchange takes place so that the mobile terminals of the motor vehicle can fulfill their respective function, that is, for example, can present current traffic information in the motor vehicle. Meanwhile, the number of mobile devices and the number of functionalities that can be useful provided only by data exchange with the environment, very large. As a rule, a driver has no control over the exchanged data volumes. This can result in undesirably high costs for data transmission. Another important aspect is the type of data disseminated. People in cars may not want something about them being passed through a mobile device to off-board devices. One way to prevent undesired data exchange is to interrupt the data connection, for example to the Internet. But then all data services are interrupted.

In terms of traffic control is out of the DE 10 2010 002 883 A1 a special communication device for a subscriber of a communication network known. By means of the communication device, mobile terminals of the motor vehicle can exchange messages with at least one vehicle-external device. For this purpose, the communication device receives messages to be transmitted from the mobile terminals of the motor vehicle. The received messages are checked for compliance. If a message does not correspond to a certain rule, a shutdown signal is sent to the sender of the message, ie the sending terminal.

From the WO 2006/133774 A1 It is known to prevent data exchange between two components within the motor vehicle in a motor vehicle when one of the components has just established a communication connection via a public, non-protected WLAN access point (WLAN) to a public music archive.

In the WO 2009/073806 A2 is described a motor vehicle with an infotainment system and a docking station for a smartphone. When docking the smartphone, the infotainment system determines the characteristics of the smartphone and decides based on the determined information which data can be exchanged with the smartphone. In order for the smartphone to respond better to the requirements of the infotainment system, the smartphone can be provided with different display modes for displaying the information, which differ in the complexity of the graphic objects to be displayed.

In the DE 10 2004 040 627 A1 is described an antivirus for receiving devices of a motor vehicle. A filter device examines all data sent by an off-board transmitting station and received in the motor vehicle, whether the data or parts of the data to be excluded from further processing in the motor vehicle.

In the DE 10 2009 042 617 B3 is described a mobile communication device with the ability to use the Internet, which does the same depending on a situation. The use is particularly location-dependent. If the motor vehicle stays abroad, only a small amount of data is downloaded from the Internet in order to save transmission costs, while domestic use is made of a flat rate that allows large amounts of image data to be downloaded.

The invention has for its object to provide in a motor vehicle, a control over the exchanged of mobile devices of the motor vehicle with external devices and / or other vehicles messages, without this resulting in an unnecessarily high restriction of communications.

The object is achieved by a motor vehicle according to claim 1 and a method according to claim 9. Advantageous developments of the invention are given by the dependent claims.

The vehicle according to the invention offers the possibility of selectively controlling the data exchange and thus preventing the transmission and / or reception of unwanted messages, while needed and desired messages can be freely sent and / or received. In the motor vehicle according to the invention this is centrally controlled independently of the number of terminals to be controlled, so that the communication behavior of the entire vehicle can be changed by a single changeover.

The vehicle according to the invention with a plurality of mobile terminals is designed in such a way that at least one of the mobile terminals, which receives messages from at least one vehicle external device and / or another motor vehicle or sends to such, each having a configuration memory, stored in which configuration data are. Due to the concrete values of the configuration data in the configuration memory, a frequency of the message exchange and / or a data volume of the exchanged messages and / or a message type of the messages, ie a message or data type, are defined in each of the plurality of mobile terminals. Such configuration memories are known, for example, from e-mail programs for personal computers. Here, for example, it can be defined as a configuration date how often an e-mail program checks whether new messages are present on the e-mail server (so-called polling time interval). Equally, however, in a motor vehicle, for example in a navigation device that receives online traffic information, be determined by a configuration date, whether and how often and with what accuracy the navigation device emits a current position of the motor vehicle to a vehicle external server for traffic information.

In this case, a plurality of terminals are preferably designed in the manner described. By now each of the terminals of the motor vehicle having a corresponding configuration memory, so the communication behavior of the motor vehicle as a whole, so the total between the motor vehicle and the at least one vehicle external device exchanged amount of data to be controlled. However, it would be very cumbersome if this changes in the motor vehicle to change the configuration behavior in each configuration memory individually by an operator should be made. This would take several minutes each time. Therefore, in the motor vehicles according to the invention, a central control unit is additionally provided, in which at least two different configuration data sets with configuration data for each terminal are stored. For example, a configuration record may be provided that configures all terminals to send and receive any number of messages of any length without any hindrance. Then none of the functionalities of the respective terminal would be limited by limiting the traffic. On the other hand, another configuration data record can be provided, for example, for the terminals receiving messages exclusively, but not transmitting them themselves. Then up-to-date information could always be displayed in the motor vehicle without endangering the privacy of the persons in the motor vehicle.

By transferring configuration data of a specific configuration data record into each terminal by the central control unit, this results in an overall configuration with regard to the communication behavior of the entire vehicle. In other words, each configuration data record defines a specific configuration mode of the motor vehicle. It is preferably provided here that the provided configuration data records implement at least one of the following communication modes, which can then be selected by means of the selection device: an online mode in which the motor vehicle transmits and receives; a silent mode in which the motor vehicle only receives; a stealth mode in which the motor vehicle neither transmits nor receives. These three, very easy-to-see communication modes allow an operator to very quickly gain control over the communication behavior of the motor vehicle.

The said control unit also includes a selection device which is set up for selecting one of the configuration data records. For example, this selection device allows an operator to select one of the configuration data sets and to select it. The selection device is furthermore configured to set the corresponding configuration data in the configuration memory of each terminal in accordance with the selected configuration data record. When a configuration data set is selected, each of the terminals is thus reconfigured by the selection device, so that overall the communication strategy of the entire vehicle changes according to the selected configuration data record.

In the motor vehicle according to the invention, one of the following mobile terminals is preferably equipped with the configuration memory described: a navigation device, an infotainment system, a mobile telephone, a media playback device, a Car-2-X communication system which can be used both via WLAN technologies, such as eg IEEE 802.11 p , as well as cellular cellular communication, such as UMTS or LTE, can transmit data. By the possibility of that Configuring the communication behavior of these mobile terminals, there is the possibility to fine tune the exchanged data volume and / or the data type (eg private data, anonymized data, position data). For example, a mobile phone may be determined not to receive text messages (Short Massage Service), but is always able to place an emergency call, for example.

The data transmission itself, ie the exchange of messages between the at least one terminal and the at least one vehicle-external device is wirelessly by a communication unit of the motor vehicle, which preferably comprises at least one of the following communication modules: A mobile radio module (GSM, UMTS, LTE), a WLAN Module, a WiFi module, a Bluetooth module, an NFC module (NFC - Near Field Communication), a Car-2-X module. By controlling these message paths can be achieved that only messages of a certain type are exchanged and / or a certain amount of data exchanged is not exceeded.

As already stated, it is preferably provided that the selection device makes it possible for an operator to decide which messages are to be exchanged. For this purpose, the selection device preferably comprises an operating device for selecting the configuration data record by the operator. Such an operating device may include, for example, a turntable, a touchpad and other controls, as well as, for example, a selection menu.

In order not to jeopardize the safety of the driver in critical situations, for example an accident, when the driver has activated, for example, the described breastfeeding or camouflage mode, so that, for example, no automatic emergency call can be placed, it is preferably provided in the motor vehicle according to the invention that the selection device a monitoring device includes, for example In case of emergency, the online mode is automatically activated again so that emergency calls or so-called e-calls can be placed. The monitoring device is therefore preferably designed to determine at least one sensor value of a motor vehicle sensor and / or at least one status message of a vehicle component in the motor vehicle and to check for a switching criterion and to switch to a previously defined configuration data set when the switching criterion is met, which then, for example, the transmission of a Emergency call allows. How the switchover criterion should look can be determined by means of simple tests. It only has to be checked which sensor values or status messages are present if there is a specific situation in which the configuration data record is to be automatically switched over by the monitoring device.

An embodiment of the motor vehicle provides here that the switching criterion comprises at least one sensor value and / or at least one message content of a status message, as they result in a crash or accident. The previously defined configuration data set comprises in this case configuration data, by which a transmission of an emergency call and / or warning signal is enabled, so that this signal can be transmitted by a terminal.

Another switching criterion comprises at least one sensor value and / or at least one message content, as they result in a driving situation endangering the driving safety. In this case too, a configuration data set is then switched over, which enables the transmission of an emergency call and / or warning signal. Thus, for example, in the event that the driver has disabled the transmission of warning signals to other vehicles in his Car-2-X module, in a critical overtaking maneuver by the monitoring device, the emission of corresponding position signals to other vehicles will still be possible, which then, for example a collision with a motor vehicle, which the driver has overlooked, can be prevented.

In addition to the control of the amount of data by the central control unit is also provided in the motor vehicle according to the invention that the driver information also be made available, which allow him to obtain knowledge about the data transfer. An embodiment of the motor vehicle has for this purpose a detection device for detecting a data quantity and / or the data type of the exchanged messages and a display device for displaying the acquired data volume or the acquired data type. For example, you can see what amount of data has already been transferred in the current month, how big the traffic is at the moment (for example, in megabytes / second) or how high the average data rate is during the journey. With regard to the type of data, it may be provided that messages are subdivided into classes, each of which indicates whether they are messages with personal data, messages with anonymous media content (for example music data) or messages relating to vehicle identity or vehicle position. The detection device can also be designed such that warnings are displayed when messages of a predetermined type are exchanged between the motor vehicle and an off-vehicle device.

Another embodiment of the motor vehicle according to the invention provides an editing device by means of which an operator can generate his own configuration data record. In other words, by setting the individual values of the configuration data of the configuration data set, an operator can generate a customized configuration data set, which results in a communication behavior of the motor vehicle, as desired by the operator. The inventive method summarizes the principle underlying the invention: At least two different configuration data sets are provided, each of which includes configuration data for setting a communication behavior of the at least one terminal. To set the amount of data and / or the type of data, one of the configuration data records is selected and each terminal is configured with the configuration data contained for this terminal in the selected configuration data record.

The method according to the invention also includes refinements which include features as have already been described in connection with the corresponding developments of the motor vehicle according to the invention. For this reason, the corresponding developments of the method according to the invention will not be described again here.

In the following, the invention is described in more detail again with reference to a concrete embodiment. For this purpose, the single figure shows a schematic block diagram of a motor vehicle 10 , which represents an embodiment of the motor vehicle according to the invention. In the motor vehicle 10 it may, for example, be a passenger car. The car 10 can in a conventional manner one or more mobile devices 12 . 14 . 16 . 18 have, four of which are exemplified in the figure. For the sake of illustration, it is assumed in the following that the terminal 12 to a navigation device NAV, at the terminal 14 to a Car-2-X communication system C2X, at the terminal 16 to a mobile phone PHONE and the terminal 18 is a media player MED, such as an MP3 player acts.

The terminals 12 . 14 . 16 . 18 can communicate with a communication device 20 of the motor vehicle 10 be coupled. The communication device 20 may be implemented by one or more communication technologies, such as a cellular communication technology, such as a UMTS module or an LTE module, a WLAN module, a WiFi module, a Bluetooth transmitter, an NFC transmitter, a Car-2 Car or Car-2-X transmitter. About the communication device 20 can the terminals 12 . 14 . 16 . 18 a radio connection 22 with one or more off-board devices 24 build, of which in the figure only one example is shown. About the radio connection 22 can the terminals 12 . 14 . 16 . 18 Messages with the device 24 change.

In the motor vehicle 10 In this case, however, the driver or another operator is in control of what messages and / or how many messages on the radio link 22 be transmitted. For this purpose, the motor vehicle 10 a message manager 26 on. The message manager 26 For example, as a control unit, as part of a control unit or as a program module for a control unit or a central computer of the motor vehicle 10 be provided. Another component of the control of the message exchange are transmitter modules 28 and receiving modules 30 that each of the terminals 12 . 14 . 16 18 as required. For example, in the example shown, the terminals must 12 . 14 . 16 to be able to broadcast messages and therefore have a transmission module 28 on. Receive messages to the devices 12 . 14 . 16 also a reception module 30 on. In contrast, the terminal 18 as media playback device MED only one receiving module 30 on, for example, to receive media data from the Internet and in the vehicle 10 play. The transmitter modules 28 and the receiving modules 30 can be used, for example, as program modules of control programs or operating systems of the terminals 12 . 14 . 16 . 18 be realized.

The transmitter modules 28 and the receiving modules 30 are configurable. For this purpose, each of the terminals 12 . 14 . 16 . 18 a configuration memory 32 in which configuration values are stored. The transmitter modules 28 (SND) and the receiving modules 30 (RCV) of the terminals 12 . 14 . 16 . 18 only generate such messages or request only such messages from the device 24 as indicated by the current values in its configuration memory 32 is determined in each case. The transmitter modules 28 and the receiving modules 30 thus control the sending and receiving as well as the decoding and encoding of messages, such as those for communication with the off-board device 24 , So for example, a Car-2-X communication, are used. The values in the configuration store 32 of each terminal 12 . 14 . 16 . 18 can be controlled by a central control unit 31 of the news manager 26 to be changed. For example, this can be any terminal 12 . 14 . 16 . 18 a program interface (API), via which the respective terminal 12 . 14 . 16 . 18 a corresponding control command from the control unit 31 to change a value in its configuration memory 32 can receive.

In the control unit 31 are multiple configuration records 34 . 40 . 42 stored, each configuration data for all devices 12 . 14 . 16 . 18 include. The message manager 26 includes the functionality to accommodate the driver's input, thereby also providing a driver desired configuration record for selection by the operator 28 can be provided. An operator can do this via an operating device 48 which, for example, in the example shown in the figure, a turntable 48 may include, for example on a display in a selection menu one of the configuration records 34 to 46 choose. After selecting a configuration record 34 to 46 controls the controller 31 the terminals 12 . 14 . 16 . 18 and thereby puts in the configuration memory 32 each terminal 12 . 14 . 16 . 18 the configuration values according to those in the selected configuration record 34 to 40 specified configuration data.

The configuration record 34 For example, to provide the described online mode (ONLINE), the configuration record 40 for silent mode (SIL), the configuration data set 42 for the stealth mode (STLTH) corresponding configuration data for the terminals 12 . 14 . 16 . 18 contain. The stealth mode STLTH according to the configuration record 42 provides an emergency stop functionality of the networking of the motor vehicle 10 with the vehicles external devices 24 dar. The configuration record 44 For example, it may be a configuration record (CONF) set or designed by an operator himself. The configuration record 46 may have a security configuration (SEC), which ensures that, for example, the terminal 16 As telephone module PHONE an emergency call or an e-call via the communication device 20 can settle.

The actual between the vehicle external device 24 and the other vehicle-external devices on the one hand and the terminals 12 . 14 . 16 . 18 On the other hand transmitted amount of data, for example, by a monitoring device 50 for the traffic (TRFFC) determined, for example, be measured, and in the motor vehicle 10 for example, the driver via a display device 52 For example, a screen in the center console or in the instrument cluster or a head-up display, are displayed.

This can then be used to provide information on the current and updated data exchange. The configuration records 34 to 46 the control unit 31 offer different communication levels, which can be activated if necessary. This can be done via the operating device 48 controlled by the driver. The choice of configuration records 34 to 46 as well as the display of the values for data transfer can via a common display device 52 be realized for example in the form of an information menu.

Furthermore, the control unit contains 31 also a logic for evaluating a situation context, which allows to automatically select and set the different activation levels. For this purpose, a monitoring device 54 , For example, an additional program module, be provided, which a situation context SIT in the motor vehicle 10 determined. The situation context SIT can in the described manner by measuring sensor values and evaluating status messages of motor vehicle components of the motor vehicle 10 be determined.

The vehicle thus offers the driver the opportunity to control the data exchange itself and is therefore the driver more self-determination, but without endangering the safety of the driver in critical situations, such as an accident.
