用于车辆的人员保护装置的至少一个点火电路的监测装置和用于运行监测装置的方法
摘要：
本发明涉及一种用于车辆(520)的人员保护装置(522)的点火电路(102)的监测装置(100)，其中，点火电路(102)设计用于在施加超过电压阈值的点火电压和/或超过电流阈值的点火电流时激活人员保护装置(522)，其中，监测装置(100)具有控制装置(104)和通过控制装置(104)的电压源端子(VH_lim)连接的电压源(106)，其中，控制装置(104)通过高侧点火电路端子(IGH1)与点火电路(102)的第一供电端子(ZK1+)连接并且通过低侧点火电路端子(IGL1)与点火电路(102)的第二供电端子(ZK1‑)连接。监测装置(100)设计为使得控制装置(104)的布置在电压源端子(VH_lim)和高侧点火电路端子(IGH1)之间的高侧电流源(IH)的空载电压至少相应于所述电压阈值，特别是所述空载电压相应于点火电路的至少一个点火电压。
摘要（英）：

A monitoring device for an ignition circuit for a personal protection device for a vehicle. The ignition circuit activates the personal protection device when an ignition voltage is present that exceeds a voltage threshold value and/or an ignition current is present that exceeds a current threshold value. The monitoring device has a control device and a voltage source connected via a voltage source terminal of the control device. The control device is connected via a high-side ignition circuit terminal to a first supply terminal of the ignition circuit and via a low-side ignition circuit terminal to a second supply terminal of the ignition circuit. The monitoring device is fashioned such that a no-load voltage of a high-side current source of the control device situated between the voltage source terminal and the high-side ignition circuit terminal corresponds at least to the voltage threshold value.
