Vehicle electrical systems
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.
1. An electrical system comprising:
a generator;
a plurality of electrical subsystems that each includes its own energy supply; and
a plurality of consumers, wherein:
at least one of the consumers, which is classified with an average safety classification, is suppliable with power from either one of at least two of the electrical subsystems; and
at least one of the consumers, which is not classified with a safety classification, is suppliable with power from only one of the electrical subsystems, and
the at least one consumer having an average safety classification is situated symmetrically between two of the vehicle electrical subsystems;
wherein each of the plurality of electrical subsystems includes its own energy supply, wherein each of the energy supplies includes a battery, wherein the generator is coupleable to one of the energy supplies via an intelligent switch, which includes a switch function and a diode function, and wherein the generator is coupleable to another of the energy supplies via another intelligent switch, which includes another switch function and another diode function.
2. The electrical system of claim 1 , 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.
3. The electrical system of claim 1 , further comprising:
at least one switch by which at least one of the electrical subsystems is separable from the electrical system.
4. The electrical system of claim 1 , further comprising:
at least one switch by which one of the consumers is separable from the electrical system.
5. The electrical system of claim 1 , wherein the at least one consumer classified with the average safety classification is situated symmetrically between two of the electrical subsystems.
6. The electrical system of claim 1 , wherein the electrical system is part of a motor vehicle.
7. The electrical system of claim 1 , wherein the electrical system is part of a mobile work machine.
8. 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 either one of at least two of a plurality of vehicle electrical subsystems; and
supplying power to the consumer that is not classified with a safety classification from only one of the plurality of vehicle electrical subsystems;
wherein the at least one consumer having an average safety classification is situated symmetrically between two of the vehicle electrical subsystems, and
wherein each of the plurality of electrical subsystems includes its own energy supply, wherein each of the energy supplies includes a battery, wherein the generator is coupleable to one of the energy supplies via an intelligent switch, which includes a switch function and a diode function, and wherein the generator is coupleable to another of the energy supplies via another intelligent switch, which includes another switch function and another diode function.
9. The method of claim 8 , further comprising:
separating at least one of the consumers from at least one of the electrical subsystems by operating a switch.
10. The method of claim 8 , further comprising:
separating at least one of the electrical subsystems from a vehicle electrical system by operating at least one switch.
