- the ad hoc network radio communication enables spontaneous communication of vehicles participating in the traffic with the environment or with each other.
- This bidirectional ad hoc network radio communication is a short to medium range with short access time and high data rate.
- this communication is realized by means of mobile devices, so-called on-board units (OBUs), whereby communication by the formation of ad hoc networks is initially a public communication. This can be trained by an additional authentication as private communication.
- OBUs on-board units

- One of the two communication units is designed as a WLAN-based communication unit with which, for example, a DSRC or ITS-G5 communication would also be possible.
- the other communication unit is realized as a wireless access and driving authorization unit (RKE, Remote Keyless Entry), wherein all communication units are controlled by a common central computer of the vehicle. This is expensive because many different communication units are provided, all of which must be accommodated in the vehicle.
- RKE Remote Keyless Entry
- WO 2007/068542 A1 discloses a communication system of a motor vehicle having a control unit and a transmitting and receiving unit connected thereto, wherein an evaluation of the orientation of the vehicle relative to a reference direction takes place in the control unit.

- the antenna unit of the antenna device according to the invention is integrated in a housing and includes all the elements required for external communication.
- the antenna unit has at least one grain Communication connection for an in-vehicle communication with other vehicle units on.
- Such a centralized antenna device has the advantage that particularly short high-frequency cable routes can be realized because all components of the antenna device necessary for the communication are integrated in the antenna unit.
- the antenna unit may be mounted at a suitable location in the vehicle roof. By limiting it to the functional elements required for the communication, it is also possible to apply these elements for high operating temperatures, such as arise when mounting the antenna unit under the vehicle roof, in order to enable reliable communication.
- the antenna device and its arithmetic unit By arranging the antenna device and its arithmetic unit to carry out all external communication types, the external communication can be processed very advantageously in the sense of batch processing (ie as a flexible stack), in which all modules which have requirements for external communication meet these requirements sending or receiving data simply to the antenna device, which then only takes over the actual communication technology.
- the arithmetic unit the antenna device or the antenna NEN unit according to the invention have a high-temperature computer or processor, which is able to operate at operating temperatures up to well 100 0 C, in particular to about 105 0 C or 110 ° C. Especially in the roof area of a vehicle such temperatures can occur in the dark painted vehicles in summer.
- this antenna unit is designed so that the electronics are located on the inside of the roof and connected via a through-hole through the roof with the antennas on the outside of the roof.
- this side of the housing is even made of this thermally conductive material.
- the essential electronic components can then be fixed in directly thermally conductive connection with this thermally conductive material in the housing of the antenna device or the antenna unit.
- the housing is protected on the one hand from heat as well as possible and is able to dissipate as well as possible the heat absorbed by the vehicle roof or generated by the electronic components on the other side.

- These several different units which work together to organize, prepare, and prepare the data for transmission, form a more detailed stack in batch processing from various downstream and self-contained functional units. Due to the division into different modules (functional units), the arithmetic unit of the antenna unit of the antenna device is relieved and requested computing power in other units of the antenna device.
- the concentration of all tasks of communication and administration in the (possibly distributed to different modules) computing unit of the antenna device ensures that a simple modular design is possible and the Connected vehicle units would have no intelligence in terms of technical communication, which is concentrated exclusively in the antenna unit.

This is particularly useful if the arithmetic unit is set up, in addition to performing the actual communication also be used for network administration and data processing. In this case, depending on the amount of information to be processed simultaneously and at the same time, the computing power may no longer be sufficient, resulting in delays in processing and communication. For this reason, it makes sense if in particular the computing services not directly serving the technical implementation of the communication are optionally outsourced to other computing units via the internal network of the vehicle. According to the invention, these can also be arithmetic units which are no longer provided with the network administration or data processing of the data to be received or transmitted and therefore are no longer part of the antenna device in a broader sense.
- a mobile radio unit for organizing the cellular radio communication can be provided, which is either integrated into the housing of the antenna unit or formed in a separate housing and communicates with the antenna unit via an in-vehicle communication.
- the separate housing may also be a communication control unit into which part of the network management and / or data preprocessing of bidirectional ad hoc network radio communication may be integrated.

- This information is also relevant in the context of the ITS standard and is therefore transmitted to other road users via bidirectional ad hoc network radio communication (in particular C2C and C2X communications). Since these data converge centrally in the security control unit 25 of the vehicle or are detected, it makes sense to reprocess these data in the second part 24 of the DSRC or ITS G5 components 24 and to pass them on to the antenna unit 22 already in a processed form. In contrast to the first embodiment, this enhances the batch processing of the information and reduces the overall data transfer.

However, this is by no means limiting. Furthermore, a data exchange between the security unit 25 and the multimedia unit 26 may occur.
- FIG. 3 shows a further embodiment of an antenna device 31 according to the invention with an antenna unit 32, for which only the aspect of the DSRC or ITS-G5 communication in the context of the bidirectional ad hoc network communication is explained in more detail below.
- the antenna unit 32 corresponds to the antenna units 22 and 2, wherein in addition a mobile radio unit and an emergency call unit can be integrated in the antenna unit 32 or connected separately thereto.
- the antenna unit 32 contains only the first part of the DSRC or ITS-G5 components 23 directly for the technical realization of receiving and transmitting the data in the frame DSRC or ITS-G5 standards are necessary.
- the Data processing and management takes place in the context of the second part of the DSRC or ITS-G5 components 24 in a vehicle unit 33 designated as an ITS sensor, which is equipped with vehicle and possibly environment sensors 34 and a positioning unit 36.
- the data collected and processed by the ITS sensor are regularly required in the context of DSRC or ITS-G5 radio communication and processed in the second part 24 of the DSRC-ITS components.
- the ITS sensor unit 33 is then connected to the remaining vehicle components 35 in order to be able to exchange these data and information as well.
- bidirectional ad hoc network radio communication is strictly hierarchical, and the aspect of batch processing is particularly emphasized.
- the antenna unit 32 can be made more favorable, in particular for vehicles which do not fully utilize the possibilities of the ITS standard. In the future, these will be above all cheaper vehicles of the lower class as well as of the lower middle class. If required, the ITS sensor unit 33 can then be retrofitted, which is connected to the antenna unit 32 and provides the entire range of functions of the ITS standard. This is easy to retrofit, so that the batch processing in the embodiment of FIG. 3 is particularly flexible. LIST OF REFERENCE NUMBERS
