| Zusammenfassung: | The invention relates to a method for detecting a battery (5) acting inside a voltage supply system (1) of a motor vehicle, wherein a generator (2) generates an electrical AC voltage and this AC voltage is rectified by a rectifier (3), and the rectified voltage (6) is measured and analysed by a control unit (7), wherein the absence of a battery (5) acting in the voltage supply system (1) is diagnosed when analysing oscillation properties of the voltage (6) outside a tolerance range. The invention also relates to an associated voltage supply system (1).
本发明涉及种用于检测在机动车的电压供应系统(1)之内起作用的蓄电池(5)的方法，其中，通过发电机(2)产生交流电压，通过整流器(3)整流所述交流电压，通过控制单元(7)测量和分析整流后的电压(6)，其中，在分析到所述整流后的电压(6)的振动特性处于公差范围之外时，诊断为在所述电压供应系统(1)中起作用的蓄电池(5)的缺失。本发明还涉及种对应的电压供应系统。 |
