Abstract

A device is proposed for ascertaining distance and transmitting data in a motor vehicle. It has a transmitting arrangement for generating and emitting a radar signal. A receiving arrangement receives a radar signal. It is characterized in that switchover arrangements are provided which cause the transmitting and/or receiving arrangement to operate either in a radar operating mode for detecting the distance and/or speed of a further object, or in a data-exchange operating mode for the exchange of data with a transceiver. Specific functions are enabled in dependence on the data exchange.
