用于获取渐变的静态电流错误的方法
摘要：
本发明涉及一种用于识别车辆的有误差的静态电流特性的方法和一种对应的装置。特别是描述了一种用于获取车辆(100)的车载电网的静态电流阈值(210)的方法(400)。该方法(400)包括获取(401)相应多个车辆(100)的多个静态电流数据集(310)。在此车辆(100)的静态电流数据集(310)包括车辆(100)的静态电流测量值和车辆(100)的一个或多个车辆参数(301)的值。该方法(400)还包括通过对所述多个静态电流数据集(310)的聚类分析来获取(402)多个等级(311，312，313)。在此等级(311，312，313)包括车辆组(331，332，333)以及用于车辆组(331，332，333)的等级静态电流(321，323，333)，所述车辆组通过一个或多个车辆参数(301)的一个或多个值来描述。此外该方法(400)包括基于所述多个等级(311，312，313)的至少一个等级静态电流(321，323，333)来确定(403)静态电流阈值(210)。
摘要（英）：

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.
