Claim:
1. A device for deactivating high-voltage components of a vehicle, wherein the device carries out a fault analysis of the high-voltage components following the detection of a vibration and disconnects the high-voltage components in response to the fault analysis revealing a fault in the high-voltage components, wherein the device distinguishes a minor accident from a major accident based on the detection of the vibration is detected, and wherein the device irreversibly disconnects the high-voltage components from a vehicle network without a fault analysis in the event of a major accident, carries out the fault analysis in the event of a minor accident, and disconnects the high-voltage components only after the fault analysis reveals a fault in the high-voltage components, wherein the device initiates a self-diagnosis of one or more of the high-voltage components as part of the fault analysis, initiates an interlock check, detects a line interruption, initiates an insulation resistance measurement, and determines a voltage status of a high-voltage heating system and/or of an electronic air-conditioning compressor.
