The present disclosure relates to a system for a motor vehicle for exchanging information with at least one further motor vehicle, wherein the system has a central processing unit with a processing core, which is connected to at least one antenna module, wherein the at least one antenna module is designed to exchange signals containing information with the at least one further motor vehicle, wherein an application for carrying out a motor vehicle to motor vehicle communication is installed in the processing core, wherein the processing core is designed to control the at least one antenna module by carrying out a signal processing.

System and method for exchanging information

The disclosure refers to a roof antenna module and to a method for operating the roof antenna module, wherein a communication control unit couples at least one transceiver with at least one bus connection and communication messages are transmitted between the at least one transceiver and the at least one bus connection. This approach prevents undesired manipulation of the motor vehicle from the outside. This approach uses a filter device of the communication control unit, that forwards a control instruction to the at least one bus connection only if the control instruction fulfills a predetermined safety criterion.

Motor vehicle roof antenna module, motor vehicle and method for operating the roof antenna module

A switching apparatus alternately connects a mobile radio module and an E-Call controller to an antenna/ The switching apparatus includes a first signal input, a second signal input, an antenna connection and a changeover device that changes between a first switching state and a second switching state, based on at least one switching signal. In the first switching state, only the first signal input is electrically connected to the antenna connection, and in the second switching state, only the second signal input is electrically connected to the antenna connection. To prevent a connected transmission devices from diagnosing decoupling from the antenna connection as a fault, in at least the second switching state the changeover device electrically connects the signal input that is decoupled from the antenna connection to a terminating device which emulates an antenna at the signal input that is connected to the terminating device.
