The invention relates to an on-board power supply system (1) for a vehicle (F), comprising an electrical supply path (SVP), a first voltage measuring device (12) at a first end of the supply path (SVP), a second voltage measuring device (13) at a second end of the supply path (Lt), and an evaluation device (10) connected to the voltage measuring devices (12, 13), the evaluation device is designed to subject a first voltage curve (K [U (12)]) measured by means of the first voltage measuring device (12) and a second voltage curve (K [U (13)]) measured by means of the second voltage measuring device (13) to a cross-correlation, and to determine an abnormal degradation state of the supply path (SVP) if the result of the cross-correlation satisfies a predetermined criterion.
本发明涉及一种用于交通工具(F)的供能机载电网(1),所述供能机载电网具有:电气的供电路径(SVP)、在供电路径(SVP)的第一端部上的第一电压测量装置(12)、在供电路径(Lt)的第二端部上的第二电压测量装置(13)以及与电压测量装置(12、13)连接的评估装置(10),所述评估装置设置用于,使借助于第一电压测量装置(12)测量的第一电压曲线(K[U(12)])和借助于第二电压测量装置(13)测量的第二电压曲线(K[U(13)])经历互相关,并且如果所述互相关的结果满足预定的标准,则确定供电路径(SVP)的异常的退化状态。
