Abstract: A method for insulation fault location in a branched, ungrounded power supply system includes determining an insulation fault position being carried out in combination with evaluating information for identifying a faulty cable outlet according to the method of time-domain reflectometry. Furthermore, the invention relates to a method for insulation fault identification in a branched power supply system and for status monitoring of the branched power supply system, an image of all reflection positions on the power supply system being carried out based on a method of time-domain reflectometry. Moreover, the invention relates to a device for insulation fault location in a branched, ungrounded power supply system having the function units insulation fault test apparatus and insulation fault evaluation device having a measuring current transformer, the device comprising a time-domain reflectometer having a controller so as to implement the method according to the invention.

Abstract: The invention relates to a control system for a motor vehicle, including a first electronic control system for controlling a first load current of a first load and a second electronic control system for controlling a second load current of a second load. The first electronic control system and the second electronic control system are arranged at a distance from one another and are connected to one another. At least the second electronic control system has a sleep mode and an operating mode, and only the first electronic control system can switch the second electronic control system from the sleep mode into the operating mode.
