Vehicle electrical system for a vehicle and method for supplying energy to a safety-relevant consumer of a vehicle electrical system

摘要

The system has a safety-relevant consumer load (7) e.g. shift-by-wire-system or electromechanical brake, that is electrically connected with a primary system (1a) and a secondary system (1b). The load is redundantly supplied with power by the primary and secondary systems. The primary and secondary systems are decoupled from one another for power supply of the consumer load. A recuperation device (8) e.g. double layer capacitor, is connected to the secondary system, where power stored in the recuperation device is partially supplied to the consumer load in a situation-dependent manner. An independent claim is also included for a method for power supply of a safety-relevant consumer load in an electrical system of a vehicle.
