Abstract: A method for the automated selection of data sets for a method for machine learning for detecting operating variables of a motor vehicle, in which methods, measuring signal sequences for particular operating variable ranges of the motor vehicle, are detected during the operation of the motor vehicle. In the method, the operating variable ranges are assigned memory areas, each including multiple slots, each of which is configured to store a data set containing a detected measuring signal sequence, and data sets already stored in the slots being overwritable with data sets newly detected instantaneously for the same memory area in each case. For each slot of a memory area in which a data set is stored, an estimated slot error value is formed and stored together with the measuring signal sequence. The data sets, whose estimated slot error value is comparatively low, are preferably overwritten.
