Redundant power supply for security - related consumers in an onboard network

Multiple consumers (V1-V4,11a-11d) are supplied with power via a generator (1) as a first source of power for generating a 42 volt voltage and a 14-volt battery (2) as a second source of power. In order to improve failure safety in the safety-relevant consumers (11a-11d), the consumers are connected to the first source of power via a first supply wire (3) and to the second source of power via a second supply wire (4).
