The invention relates to the technical field of automobile electronic control, and discloses a line fault diagnosis method, which comprises the following steps of: if a battery distribution unit (PDU) receives a power-on instruction, enabling the PDU to enter at least one running state from a standby state in sequence, performing line detection in each running state in the at least one running state, and determining at least one detection result; if the detection result corresponding to the current operation state represents normal, enabling the PDU to enter a next operation state; and if the detection result corresponding to the current operation state represents a fault, determining a preset processing method corresponding to the operation state. According to the technical scheme provided by one or more embodiments disclosed by the invention, the PDU can determine whether a fault exists in the line in each operation state, and the corresponding preset processing method is determined, so that the reliability and the stability of the line in different operation states are improved, and the service life of the line is prolonged.

    本发明涉及汽车电子控制技术领域,公开了一种线路故障诊断方法,若电池分配单元PDU接收到上电指令时,使所述PDU从待机状态依次进入至少一个运行状态,在所述至少一个运行状态中每个运行状态进行线路检测,确定至少一个检测结果;若当前运行状态对应的检测结果表征正常时,使所述PDU进入下一运行状态;若当前运行状态对应的检测结果表征故障时,确定所述运行状态对应的预设处理方法。本发明公开的一个或者多个实施方式提供的技术方案,可以使PDU在每个运行状态确定线路中是否存在故障,并确定对应的预设处理方法,从而提高线路在不同运行状态下的可靠性与稳定性,增加线路的使用寿命。
