• - eine Filtereinrichtung zum Filtern der empfangenen Daten,

wobei die Filtereinrichtung mit der Empfangseinrichtung verbunden ist und wobei die Filtereinrichtung ausgestaltet ist, abhängig von in den Daten enthaltenen Informationen zu entscheiden, ob die Daten oder Teile der Daten von einer weiteren Datenverarbeitung in dem Fahrzeug ausgeschlossen werden.Furthermore, an arrangement for transmitting data to a vehicle, in particular to a road motor vehicle, is proposed, which has the following:

• A receiving device for receiving the data transmitted wirelessly to the vehicle,
• a filter device for filtering the received data,

wherein the filter device is connected to the receiving device and wherein the filter device is configured to decide, depending on information contained in the data, whether the data or parts of the data are excluded from further data processing in the vehicle.

By the filtering can unimportant and / or harmful Data are sorted out, so the facilities and systems reliable in the vehicle to process the important information. The facilities and Systems are therefore not affected by the processing of unimportant data burdened or are preserved from damage.

at a development of the solution according to the invention is the received data Assigned a degree of importance and can take the data into account of the degree.

Preferably the filtering is adjustable and configurable. In this way is it possible to get information, which were sent without request to the vehicle (so-called push Messages), z. As advertising, chat messages, automatic information download when approaching cities, Attractions and / or restaurants, latest offers from car dealers and / or supermarkets or only selected information for allow or allow further data processing.

Especially The filter device may be provided with a plurality of different ones Filter profiles are operated, each of the filter profiles at least partially determines the operation of the filter device. For example can Filter profiles are created for a specific period of time the operation of the filter device are used, for. B. night drive or day trip. Furthermore you can For example, filter profiles are created for specific Events and / or situations are used, eg. B. profiles for meetings while the ride, for a business trip and for a family trip.

at An embodiment of the invention is dependent on a result of Filtering decided whether to the sender of the received data and / or sent a message to a potential sender of data becomes. This message contains in particular the information that the reception of certain (further) Data not wanted is. Optionally, the reception of this further data from the filter device be blocked. In this embodiment, the transmission of unwanted Data in the communication network effectively reduced.

Unimportant Information is z. Advertising and chat messages. However, you can the decision as to whether information is important or unimportant in the Be taken in different ways over time. For example may depend on the decision be taken from the current driving situation of the vehicle.

Especially can the filtering depending on an operating condition of the vehicle and / or depending on an operating condition a device of the vehicle (eg at low Tire pressure or low level in the fuel tank). this makes possible it depends on the filter device from the operating state automatically an answer to one with the Data received message or request to send. For example, the Answer containing the information that a vehicle driving desired interlocutor and / or a device in the vehicle currently unreachable is, because of the conversation partner already on the phone. However, such an automatic answer can then be sent if the filtering does not depend on performed the operating condition becomes.

The Driving situation of the vehicle and the operating condition can under the term "context" summarized become. In one embodiment of the invention, the filtering the received data under consideration the combination of the driving situation and the operating condition performed and the importance depends on the context established. In particular, you can in determining the importance of messages or information of control devices and / or on-board electronics of the vehicle considered become.

Z. B. is provided in the vehicle, a tire pressure measuring device, the above a signal line for transmission such messages is connected to the filter device. provides The tire pressure gauge determines that the current tire pressure is too low, it gives a corresponding message to the filter device out. The message increases the importance of data that information about In-vehicle equipment included with which the tire pressure can be adjusted. For example, the vehicle receives before or at Reaching a station located on the route, the one Tire pressure measurement service offers, via the communication network corresponding information. The filter device classifies this information now as important. For example, the driver receives a result as a result appropriate message, as a combined acoustic and optical Signal (eg a voice message from the on-board computer and a flashing light a signal light). If the tire air pressure is correct, it will discarded the message received from the gas station, d. H. become the corresponding data excluded from further processing.

One Another example relates to a temporary traffic incident, e.g. B. because of a daily construction site. After receiving data, the information about the If the day's construction site is included, these data will be provided by the Filter device classified as important and to the navigation system forwarded to the vehicle. The navigation system then calculates a new route. The news about the existence of the day construction site does not have to be communicated to the driver in this case. Generally is therefore between data classified as important to differentiate such data, which leads to an explicit notification of the Lead driver, and to distinguish such data, which are processed further, but where no explicit notification of the driver takes place. In particular, in that the filter device, the data or Information to appropriate appropriate facilities in the vehicle Forwarding can be a burden on the driver with unnecessary information be avoided.

One third example generally concerns the warning of vehicle internal and - external Safety equipment. For example, an existing in the vehicle Attack detection system through the received data in advance of possible attacks be warned and / or may contain the information contained in the received data Information for analysis purposes to be forwarded to external systems.

The invention makes it possible to detect harmful contents of data and to keep them away from the facilities and systems of the vehicle. In particular, the filtering device analyzes contents and / or attachments of received messages. Preferably, the filter device independently requests security information (eg updates from the Internet) in order to obtain a current state of the functionality. In particular, this can z. As viruses, worms and unwanted commercial messages are excluded from further processing and / or complete the relevant data dig deleted.

The Filter device can be used as a common interface of a plurality or all the facilities of the vehicle that are connected via the communications network received data to the outside world be designed. For example, the filter device a take over central backup function and if necessary further safety mechanisms in the vehicle and / or outside of the vehicle (eg by sending a message). Optionally, the filter device can take on additional security tasks.

Further For example, the filter device may receive various information from Data and / or various information from received data and from other data, thus creating new ones Generate information.

Farther The filtering device can not only listen to received messages respond, but also actively and targeted content and information from other participants in the communication network, in particular by other vehicles, retrieve and / or request.

One embodiment The invention will now be described with reference to the accompanying drawings. The only figure of the drawing shows:

1 an arrangement for receiving and processing data in a vehicle.

In 1 is a vehicle, such as a passenger car, schematically indicated by a frame, with the reference numeral 1 is designated. The vehicle 1 has a receiving device 5 on, the input side via a radio link 3 connected to a communication network for the wireless transmission of data. The communication network is, for example, a vehicle-vehicle communication network in which data is transmitted directly between vehicles.

The receiving device 5 is the output side with an input of a filter device 7 connected. For example, the receiving device 5 at the same time as transmitting device for sending data from the vehicle 1 be designed to other participants of the communication network. Furthermore, the receiving device 5 be configured to perform all the functions that are required for a radio transmission of signals and for extracting the data transmitted with the signals.

Different outputs of the filter device 7 are with a data store 6 , a signaling device 9 , a navigation device 11 and control devices 13 (For example, (have an on-board computer and / or control means for controlling a drive motor of the vehicle). Instead of various outputs, a data bus can be provided, via which the filter device 7 connected to said other facilities. Preferably, the filter device 7 however, the only interface between the other devices and the receiving device 5 represents.

In the 1 shown arrangement is operated, for example, as follows: the receiving device 5 receives via the radio link 3 continuously or repeatedly radio signals from which it extracts data. The data is sent to the filter device 7 which first checks the data for contained elements (eg, viruses and worms) that damage the devices in the vehicle 1 or cause harm to other participants in the communication network. These elements and optionally also data transferred in connection with these elements will be deleted. The data filtered in this way in a first step may be completely or partially stored in the data memory 6 get saved.

Furthermore, these data are then analyzed in a second step to determine whether they can be excluded from further processing. In this case, the data are preferably evaluated as to their importance, depending on the current driving situation and on the current operating state of the vehicle. Less important data is deleted or for possible later processing in the data store 6 saved. More important data will be provided by the filter device 7 to other facilities in the vehicle 1 forwarded to the data processing.

Preferably, the filter device decides 7 in a third step, on the basis of the information contained in the data or on the basis of address information (which, for example, is contained in a specific field of a data structure) to which the data is sent to the filter device 7 Connected facilities, the data will be forwarded.

Optional finds in the filter device 7 after the step of eliminating harmful elements, a preprocessing of the data takes place. This z. B. information contained in different parts of the received data are linked together.
