A method is described for reading out sensor data from an intermediate memory written by at least one sensor to the intermediate memory at a data-transfer rate (Tpas). A sampling rate (Tsg) is selected in such a way as to avoid an overflow of the intermediate memory and all buffered sensor data is read into a control unit memory at the predetermined sampling rate (Tsg), the intermediate memory generating a message (RBE) if no new sensor data is present in the intermediate memory at the time of sampling.
