Abstract
A method and a corresponding device are provided for recognizing a faulty quiescent current behavior of a vehicle, in particular for identifying a quiescent current threshold value for an electrical on-board network of a vehicle. The method includes the identifying of a plurality of quiescent current data sets of a corresponding plurality of vehicles. A quiescent current data set of a vehicle includes a quiescent current measured value of the vehicle and a value for one or a plurality of vehicle parameters of the vehicle. The method furthermore includes the identifying of a plurality of classes via cluster analysis of the plurality of quiescent current data sets. A class includes a vehicle group which is described by one or a plurality of values for one or a plurality of vehicle parameters, and a class-quiescent current for the vehicle group. The method determines a quiescent current threshold value based on at least one of the class-quiescent currents of the plurality of classes.
