The invention relates to an on-board motor vehicle electrical system (1) comprising a first power supply system (2a) and a second power supply system (2b). The first power supply system (2a) has a first power supply with a relatively low voltage and the second power supply system (2b) has a second power supply with a relatively high voltage. Furthermore, the first power supply system (2a) and the second power supply system (2b) are DC-insulated from each other and are connected to each other in a signal-transmitting manner by a coupling element (3). The second power supply system (2b) has at least one electrical switching element (4) for a load (5), and the on-board motor vehicle electrical system (1) has a control device (6) for controlling the load (5) by means of the respective switching element (4). According to the invention, the coupling elements (3) are connected to the respective switching elements (4) in a signal-transmitting manner by means of the control device (6).

    本发明涉及一种车载机动车辆电气系统(1),其包括第一电源系统(2a)并且包括第二电源系统(2b)。所述第一电源系统(2a)具有带有相对低的电压的第一电源,而所述第二电源系统(2b)具有带有相对高的电压的第二电源。而且,所述第一电源系统(2a)与所述第二电源系统(2b)彼此直流绝缘,并且彼此以信号传递的方式由联接元件(3)连接。所述第二电源系统(2b)具有至少一个用于负载(5)的电切换元件(4),并且所述车载机动车辆电气系统(1)具有控制装置(6),所述控制装置(6)用于通过相应的切换元件(4)控制所述负载(5)。根据本发明,所述联接元件(3)以信号传递的方式通过所述控制装置(6)连接至相应的切换元件(4)。
