Description

Transfer of data to a vehicle

The invention relates to a method and an arrangement for transmitting data to a vehicle, wherein the data is transmitted wirelessly in a vehicle-vehicle communication network and / or in a communication network with fixed transmitting stations to the vehicle. In particular, the invention relates to the transmission of data to a road vehicle, but is not limited to this case. A road motor vehicle is understood to mean a motor vehicle which is suitable for operation on roads. It can also be a off-road vehicle.

In such communication networks, for example, the vehicle may be permanently in communication with other subscribers (eg, vehicles) and / or with transmitting stations (eg, so-called hotspots positioned along the route). In this case, data can be transmitted to the vehicle containing information of different types. For example, so-called chat messages are transmitted, which contain less important information for the operation and safety of the vehicle, and / or are transmitted data containing safety-related information, such as the road condition or an accident.

It is an object of the present invention to provide a method and an arrangement of the type mentioned above, with which the use of data containing important information can be ensured in the vehicle. In particular, the resources available in the communication network for the transmission of data should also be spared or used efficiently. These resources are, in particular, the available bandwidth or data transmission rate of a communication connection in the communication network and the connection time available for the transmission of the data.

A method is proposed in which the data is transmitted wirelessly in a vehicle-vehicle communication network and / or in a communication network with fixed transmitting stations for transmitting the data to the vehicle,

the data is received by the vehicle,

- the received data are filtered and

- The filtering is automatically determined depending on information contained in the data, whether the data or parts of the data are excluded from further data processing in the vehicle.

There is also proposed an arrangement for transmitting data to a vehicle, in particular a road motor vehicle, comprising:

- one. Receiving means 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 designed 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 filtering, unimportant and / or harmful data can be discarded so that the equipment and systems in the vehicle can reliably handle the important information. The facilities and systems are thus not burdened by the processing of unimportant data or are preserved from damage.

In a further development of the solution according to the invention, a degree of importance is assigned to the received data and the data can be further processed taking into account the degree.

Preferably, the filtering is adjustable and configurable. In this way it is possible to send information that has been sent to the vehicle without a request (so-called push messages). As advertising, chat messages, automatic information download when starting cities, attractions and / or restaurants, recent offers from car dealers and / or supermarkets, herauszufiltem or only selected information for further data processing or let through. In particular, the filter device can be operated with a plurality of different filter profiles, wherein each of the filter profiles at least partially determines the operation of the filter device. For example, filter profiles can be created that are used for a certain period of operation of the filter device, eg. B. night drive or day trip. Furthermore, for example, filter profiles can be created that are used for specific events and / or situations, eg. B. Profiles for meetings while driving, for a business trip and for a family trip.

In one embodiment of the invention, it is decided, depending on a result of the filtering, whether a message is sent to the sender of the received data and / or to a potential sender of data. This notification contains in particular the information that the reception of certain (further) data is not desired. Optionally, the reception of these further data can be blocked by the filter device. In this embodiment, the transmission of unwanted data in the communication network is effectively reduced.

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

In particular, the filtering may be performed depending on an operating condition of the vehicle and / or depending on an operating condition of a device of the vehicle (eg at low tire pressure or low fuel tank level). This allows the filter device to automatically respond to a message or request received with the data, depending on the operating state. For example, the answer may include the information that a desired interlocutor traveling with the vehicle and / or a device in the vehicle is currently unavailable, perhaps because the interlocutor is already on the phone. However, such an automatic response may be sent if the filtering is not performed depending on the operating condition.

The driving situation of the vehicle and the operating state can be summarized under the term "context." In one embodiment of the invention, the filtering of the received data takes into account the combination of the Driving situation and the operating condition carried out and the importance of context-dependent. In particular, messages or information from control devices and / or on-board electronics of the vehicle can be taken into account when determining the importance.

For example, a tire pressure measuring device is provided in the vehicle, which is connected via a signal line for transmitting such messages to the filter device. If the tire pressure measuring device determines that the current tire pressure is too low, it sends a corresponding message to the filter device. The message increases the importance of data containing information about off-board equipment that can be used to adjust tire pressure. For example, the vehicle receives corresponding information via the communication network before or when reaching a gas station located at the route, which offers a tire air pressure measurement service. The filter device now classifies this information as important. For example, the driver receives a corresponding message as a result, for example as a combined acoustic and optical signal (eg a voice message from the on-board computer and a flashing of a signal light). On the other hand, if the tire air pressure is correct, the message received by the service station is discarded, i. H. the corresponding data are excluded from further processing.

Another example concerns a temporary traffic disturbance, e.g. B. because of a daily construction site. Upon receipt of data containing information on the existence of the day job site, that data is deemed important, classified, and forwarded to the vehicle's navigation system by the filter device. The navigation system then calculates a new route. The message about the existence of the daily construction site does not have to be communicated to the driver in this case. In general, therefore, for data with information classified as important, it is necessary to distinguish between those data which lead to an explicit notification of the driver and those data which are processed further but in which no explicit notification of the driver takes place. In particular, the fact that the filter device forwards the data or information to corresponding suitable devices in the vehicle, a burden on the driver with unnecessary information can be avoided. A third example generally concerns the warning of vehicle internal and external safety devices. For example, an attack detection system present in the vehicle can be warned in advance by the received data about possible attacks and / or the information contained in the received data can be forwarded to external systems for analysis purposes.

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 the corresponding data are completely deleted.

The filter device may be configured as a common interface of a plurality or all of the devices of the vehicle that can be supplied with data received via the communication network to the outside world. For example, the filter device can assume a central security function and, if required, activate further security mechanisms in the vehicle and / or outside the vehicle (eg by sending a message). Optionally, the filter device can take on additional security tasks.

Furthermore, the filter device can combine different information from received data and / or different information from received data and from other data with one another and in this way generate new information.

Furthermore, the filter device can not only respond to received messages, but also active and targeted content and information from other participants of the communication network, in particular from other vehicles, retrieve and / or request.

An embodiment of the invention will now be described with reference to the accompanying drawings. The sole figure of the drawing shows: Fig. 1 shows an arrangement for receiving and processing data in one

Vehicle.

In Fig. 1, a vehicle, such as a passenger car, schematically indicated by a frame, which is designated by the reference numeral 1. The vehicle 1 has a receiving device 5, which is connected on the input side via a radio link 3 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 connected on the output side to an input of a filter device 7. For example, the receiving device 5 can be configured simultaneously as a transmitting device for transmitting data from the vehicle 1 to other subscribers of the communication network. Furthermore, the receiving device 5 can be designed to fulfill all the functions required for radio transmission of signals and for extracting the data transmitted with the signals.

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

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

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 stored in the data memory 6 for possible later processing. More important data is forwarded by the filter device 7 to other devices in the vehicle 1 for data processing.

The filter device 7 preferably decides in a third step on the basis of the information contained in the data or on the basis of address information (which is contained, for example, in a specific field of a data structure) to which the devices connected to the filter device 7 forward the data become.

Optionally, pre-processing of the data takes place in the filter device 7 after the step of eliminating harmful elements. This z. B. information contained in different parts of the received data are linked together.
