The invention relates to a method for activating an active discharge circuit (14) by means of a control device (12) for controlling at least one electrical load (32; 32 ') of an on-board electrical system (16, 26) for a motor vehicle (10). A capacitive energy store (44, 44a) of a switching device (22, 28, 34, 36, 38, 40) is discharged, and wherein an energy source (18, 28) for the on-board electrical system (16, 26) can be coupled to the on-board electrical system (16, 26) via the switching device (22) and can be disconnected from the on-board electrical system (16, 26). In this case, the control device (12) receives a signal (S) for activating the active discharge circuit (14), checks, after receiving the signal (S), whether the energy source (18, 28) is disconnected from the on-board electrical system (16, 26) in accordance with at least a predetermined first criterion, and activates the active discharge circuit (14) only if a specific condition is satisfied, which condition is that the energy source (18, 28) is disconnected from the on-board electrical system (16, 26) in accordance with at least the predetermined first criterion.
本发明涉及一种用于通过控制装置(12)激活主动放电电路(14)的方法,用于对用于机动车(10)的车载电网(16,26)的至少一个电气负载(32;28,34,36,38,40)的电容式能量存储器(44,44a)进行放电,其中用于车载电网(16,26)的能量源(18,28)可以通过开关装置(22)与车载电网(16,26)耦联,并且可以与车载电网(16,26)断开。在此控制装置(12)接收用于激活主动放电电路(14)的信号(S),在接收信号(S)后检查能量源(18,28)是否根据至少预定的第一标准从车载电网(16,26)断开,并且只有在满足特定条件时才激活主动放电电路(14),该条件是能量源(18,28)根据至少预定的第一标准从车载电网(16,26)断开。
