Description

BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Some particularly advantageous configurations of an aspect of the invention are indicated in the subclaims. Further preferred embodiments are also set out by the following description of exemplary embodiments with reference to schematically represented figures, wherein:

[0042] FIG. 1 shows an embodiment of the communication apparatus according to the invention, and

[0043] FIG. 2 shows an embodiment of the method according to the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0044] FIG. 1 shows a communication apparatus 1 which is provided for subsequent installation in a vehicle and/or for mobile use. The apparatus comprises a transceiver TR having an antenna 1 for vehicle-to-X communication, a GNSS receiver GNSS having an antenna 2 for receiving signals from a global satellite navigation system and an inertial measurement unit IMU. The transceiver TR, the GNSS receiver GNSS and the inertial measurement unit IMU are at least mechanically protected by a housing 3 enclosing these. Furthermore, the communication apparatus has a processor CPU and a data memory (not depicted) which are likewise enclosed by the housing.

[0045] FIG. 2 shows steps of a method for execution using a communication apparatus according to FIG. 1. For example, motion detection for ascertaining a motion pattern takes place in step 21 using data captured by means of the inertial measurement unit or the GNSS receiver. In step 22, it is established on the basis of the ascertained motion pattern whether a data transmission by means of the antenna for the purpose of wireless data transmission is to be performed or to be prevented. Subsequently, as a function of the result of the step 22, the execution or prevention of the data transmission takes place in step 23 by means of the antenna for the purpose of wireless data transmission as a function of the ascertained motion pattern.

[0046] It should be pointed out in general that vehicle-to-X communication means, in particular, a direct communication between vehicles and/or between vehicles and infrastructure facilities. For example, therefore, vehicle-to-vehicle communication or vehicle-to-infrastructure communication may be involved. Where communication between vehicles is referred to within the framework of this application, this can essentially, for example, take place within the framework of vehicle-to-vehicle communication, which typically takes place without the intermediary of a mobile network or a similar external infrastructure and which is therefore to be distinguished from other solutions which, for example, are based on a mobile network. For example, vehicle-to-X communication can take place using the standards IEEE 802.11p or IEEE 1609.4. Vehicle-to-X communication can also be referred to as C2X communication. The sub-areas can be referred to as C2C (Car-to-Car) or C2I (Car-to-Infrastructure). The invention expressly does not, however, exclude vehicle-to-X communication with the intermediary of, for example, a mobile network.
