Publication number: 20230202410Abstract: A method for securing safety-relevant loads in a motor vehicle, including a main path arranged between a sub-on-board electrical system for a safety-relevant load of a motor vehicle and another sub-on-board electrical system for a non-safety-relevant load. The sub-on-board electrical system for the safety-relevant load is supplied with power by an energy store. The main path includes at least one switch, and at least one detector for detecting a current flowing through the main path. At least one additional path is provided which is connected in parallel with the main path, the additional path having at least one switch. The method includes: opening the main path upon detection of a critical state, i.e., an overcurrent and/or an undervoltage or overvoltage on the sub-on-board electrical system for the safety-relevant load. The additional path is closed or kept closed while the main path is open. The additional path is subsequently reopened.Type: ApplicationFiled: May 27, 2021Publication date: June 29, 2023Inventors: Nils Draese, Frederik Tekotte, Michael Muerken
