Beschreibung
Zusammenfassung:	An automotive electrical system for a motor vehicle comprising an internal combustion engine, the automotive electrical system comprising a main electrical power source, a secondary electrical power source, safety critical electrical loads and non-safety critical electrical loads, and an electrical switching device arranged between the main and secondary electrical power sources and at least the safety critical electrical loads and configured to selectively connect at least the safety critical electrical loads to at least one of the main and secondary electrical power sources. The electrical switching device is configured to connect at least the safety critical electrical loads to the auxiliary electrical power source during the cranking of the internal combustion engine and/or when the motor vehicle is coasting with the internal combustion engine off and the main electrical power source is faulty.
