The invention relates to a control unit circuit (22) for a motor vehicle (10), the control unit circuit (22) comprising a control unit (12) and an electrical energy storage device (14) for emergency power supply located outside the housing of the control unit (12). According to the invention, in order to form an electrical circuit (22 ') for emergency power supply, two poles (P +, P-) of the energy storage device (14) are connected to the control unit (12) via a cable (19), and one of the two poles (P +, P-) is connected to a ground potential (17) of the on-board electrical system (11) via a switching element (24), and at least one measurement circuit (27) couples each of the poles (P +, P-) to the ground potential (17) and is arranged to generate a voltage-dependent measurement signal (32). The switching element (24) is switched to a non-conductive state in the event that the respective measurement signal (32) indicates that the respective voltage is greater than a predetermined threshold.

    本发明涉及一种用于机动车辆(10)的控制单元电路(22),其中,该控制单元电路(22)包括控制单元(12)、以及位于该控制单元(12)的外壳外部的用于紧急供电的电能储存装置(14)。本发明规定,为了形成用于紧急供电的电路(22'),该能量储存装置(14)的两个极(P+,P‑)经由电缆(19)连接到该控制单元(12),并且这两个极(P+,P‑)之一经由开关元件(24)连接到车载电气系统(11)的地电位(17),并且至少一个测量电路(27)将这些极(P+、P‑)中的每一个耦合到该地电位(17)并被设置为生成与电压相关的测量信号(32)。在相应测量信号(32)表示相应电压大于预定阈值的情况下,该开关元件(24)被切换到非导电状态。
