Interlock system for monitoring at least one high-voltage component of a motor vehicle, high-voltage component, high-voltage system and methods

摘要

The invention relates to an interlock system (4) for monitoring at least one high-voltage component (2) of a motor vehicle (1) having a signal loop (5) which has a plurality of connection pairs (8), each of which has a high-voltage access point (3) at least one high-voltage component (2) are assigned, and which are electrically connectable to a short-circuit bridge (9) of the high-voltage access point (3), with a signal generator (6) for outputting a signal to the signal loop (5) and with a signal detector (10) for detecting a change in the signal transmitted via the signal loop (5) when opening at least one of the high-voltage access points (3), wherein the respective terminal pairs (8) are each electrically connected to a resistive element (R1, R2, R3), wherein electrical resistances of the respective resistance elements (R1, R2, R3) differ from one another, wherein the signal detector (10) has an evaluation unit (12) which is designed to based on the change of the signal, which by the transmission of the signal via the resistive element (R1, R2, R3), which is associated with the at least one high-voltage access point (3) to identify the at least one opened high-voltage access point.
