Abstract

In a vehicle electrical system, a method supplies a number of consumers of the system, which consumers are classified with different safety classifications, the differently classified consumers being supplied power from either one or more of a plurality of electrical subsystems according to their classifications or lack of classification.

First claim

1 - 11 . (canceled)

12 . An electrical system comprising:
a plurality of electrical subsystems that each includes its own energy supply; a plurality of consumers, wherein:
at least one of the consumers, which is classified with an average safety classification, is able to be supplied with power from at least two of the electrical subsystems; and
at least one of the consumers, which is not classified with a safety classification, is able to be supplied with power from only one of the electrical subsystems.

13 . The electrical system of claim 12 , further comprising:
at least one switch via which the at least one consumer classified with the average safety classification is supplied from the at least two of the electrical subsystems.

14 . The electrical system of claim 12 , further comprising:
at least one switch by which at least one of the electrical subsystems is separable from the electrical system.

15 . The electrical system of claim 12 , further comprising:
at least one switch by which one of the consumers is separable from the electrical system.

16 . The electrical system of claim 12 , wherein the at least one consumer classified with the average safety classification is situated symmetrically between two of the electrical subsystems.

17 . The electrical system of claim 12 , wherein the electrical system is part of a motor vehicle.

18 . The electrical system of claim 12 , wherein the electrical system is part of a mobile work machine.

19 . The electrical system of claim 12 , wherein the energy supplies of the electrical subsystems are located in a base vehicle electrical system.

20 . A method for supplying a consumer classified with an average safety classification and a consumer not classified with a safety classification, the method comprising:
supplying power to the consumer classified with the average safety classification from at least two of a plurality of vehicle electrical subsystems; supplying power to the consumer that is not classified with a safety classification from only one of the plurality of vehicle electrical subsystems.

21 . The method of claim 20 , further comprising:
separating at least one of the consumers from at least one of the electrical subsystems by operating a switch.

22 . The method of claim 20 , further comprising:
separating at least one of the electrical subsystems from a vehicle electrical system by operating at least one switch.
