A circuit assembly for plausibility checking of sensor signals, which can be generated by at least two separate sensor elements, includes at least one evaluation and control unit which receives the sensor signals via at least one interface unit and evaluates the received sensor signals for generating sensor data. A first evaluation and control unit is configured to receive the sensor signals of a first sensor element and to generate first sensor data from the first sensor signals. The first evaluation and control unit is configured to provide the generated first sensor data via at least one interface unit to a second evaluation and control unit, which receives and evaluates the sensor signals of a second sensor element to generate second sensor data. The second evaluation and control unit compares the generated second sensor data and the generated first sensor data to each other and inspects them for plausibility.
