Abstract

A communication device for a motor vehicle includes a first control unit (BDC), a second control unit (SAS), a control unit arrangement (SGA), a first data bus (SB), to which the first control unit (BDC) and the control unit arrangement (SGA) are connected for the exchange of data, as well as a second data bus (AB), to which the second control unit (SAS) and the control unit arrangement (SGA) are connected for the exchange of data. The control unit arrangement includes at least a first sensor control unit (SSG1) for controlling a first sensor and a second sensor control unit (SSG2) for controlling a second sensor. The first and the second sensor have mutually overlapping sensor acquisition ranges. The first and the second sensor control unit can exchange at least preprocessed sensor data by way of a third data bus (PB). The first and the second sensor control unit are constructed to be operated in a master-slave operation with respect to at least one functionality. By way of the first sensor control unit as the master of a first functionality (F1), first data (DFC), which are provided by the first control unit at the first data bus, are processed for the control unit arrangement.
