Method for operating an on-board power supply

Abstract

Method for operating an on-board electrical system (10) comprising a number of safety-related consumers (30, 32, 40, 42) and a number of non-safety-related consumers (34, 36, 38, 44, 46, 48), wherein the safety-related consumers (30, 32, 40, 42) and the non-safety-related consumers (34, 36, 38, 44, 46, 48) are supplied via the on-board electrical system (10), electronic disconnect switches are assigned to at least some of the non-safety-related consumers (34, 36, 38, 44, 46, 48), and the method comprises the following steps: monitoring an on-board electrical system voltage of the on-board electrical system (10), disconnecting at least one of the non-safety-related consumers (34, 36, 38, 44, 48) in the event that an undervoltage is detected. 46, 48) from the supply by actuating the associated electronic disconnect switch, categorizing the undervoltage, initiating at least one measure depending on the categorization that has taken place.
