The invention relates to a device for monitoring a power divider (18) of a motor vehicle for connecting and disconnecting two partial on-board electrical systems (10, 11), comprising at least one main path (30) and at least one additional path (50) connected in parallel to the main path (30), the main path (30) and the additional path (50) are arranged between a partial on-board electrical system (11) for at least one safety-related consumer (16, 25) and a further partial on-board electrical system (10) for at least one non-safety-related consumer (17), the main path (30) comprising at least one switching means (34) and the additional path (50) comprising at least one switching means (54), according to the invention, the power divider (18) comprises at least one evaluation device (21) in order to detect a critical state for the partial on-board electrical system (11), in particular an overcurrent and/or undervoltage or overvoltage on the partial on-board electrical system (11) for the safety-related consumer, and in order to open the switching means (34, 54) of the main path (30) and/or of the additional path (50) when the critical state (16, 25) is detected, at least one monitoring device (34) is provided in addition to the evaluation means (21), and at least switching means (54) for monitoring the current (I) flowing through the additional path (50) independently of the evaluation means (21) and for controlling the additional path (50).
本发明涉及一种用于监控机动车的功率分配器(18)的设备,所述功率分配器用于连接和分离两个子车载电网(10、11),所述装置包括至少一个主路径(30)和至少一个与所述主路径(30)并联连接的附加路径(50),所述主路径和所述附加路径布置在用于至少一个安全相关的消耗器(16、25)的子车载电网(11)和用于至少一个非安全相关的消耗器(17)的另外的子车载电网(10)之间,其中,所述主路径(30)包括至少一个开关器件(34),其中,所述附加路径(50)包括至少一个开关器件(54),其中,所述功率分配器(18)包括至少一个评估器件(21),以便识别对于所述子车载电网(11)而言危急的状态,尤其是识别在用于所述安全相关的消耗器的子车载电网(11)上的过电流和/或欠电压或过电压,并且以便在识别出所述危急的状态(16、25)的情况下断开所述主路径(30)的和/或所述附加路径(50)的开关器件(34、54),其中,除了所述评估器件(21)以外设置有至少一个监控装置(34),用于与所述评估器件(21)无关地监控流经所述附加路径(50)的电流(I)并且用于操控所述附加路径(50)的至少开关器件(54)。
