Redundant voltage supply for at least one safety-relevant consumer in car has first voltage supply connected via second decoupling element with safety-relevant consumer and second voltage supply via third decoupling element

摘要

A redundant voltage supply for at least one safety-relevant consumer in a car comprises a first voltage supply and a second voltage supply arranged in the on-board system. The first and second voltage supplies are connected via a decoupling element. The decoupling element guarantees a directed current flow from the first to the second voltage supply. The first voltage supply (1) is connected via a second decoupling element with the safety-relevant consumer (10,20) and the second voltage supply via a third decoupling element. The decoupling elements guarantee a directed current flow from the voltage supplies to the safety-relevant consumer.
