Abstract

A vehicle-supported data processing system includes a plurality of processing units communicating with one another via a bus system, which are each supplied with operating power by at least one of the at least two different vehicle electrical systems. Multiple transmitter units for control information and multiple receiver units for the control information are among the processing units. The bus system is a ring bus, in which each processing unit is connected to at least two adjacent processing units by a bus segment in each case. The ring bus is divided, by potential separating devices, which are incorporated in the bus segments which connect processing units powered by different vehicle electrical systems, into a number of sections, which is smaller than the number of the processing units.

Claims

1-11. -11. (canceled)

12. A vehicle-supported data processing system, comprising:

processing units communicating with one another via a bus system, which are powered by respectively at least one of at least two different vehicle electrical systems;

transmitter units for control information; and

receiver units for the control information being among the processing units;

wherein the bus system is a ring bus, in which each processing unit is connected to at least two adjacent processing units by respectively one bus segment, and the ring bus is divided, by potential separating devices, which are incorporated in the bus segments which connect processing units powered by different vehicle electrical systems, into a number of sections, which is smaller than the number of the processing units.

13. The data processing system of claim 12, wherein the number of the sections is equal to the number of the vehicle electrical systems.

14. The data processing system of claim 12, wherein the ring bus is bidirectional and reconfigurable.

15. The data processing system of claim 12, wherein each receiver unit one of exclusively and at least preferentially process instructions of a transmitter unit which is powered by the same vehicle electrical system as the receiver unit.

16. The data processing system of claim 12, wherein the potential separating devices include optocouplers.

17. The data processing system of claim 12, wherein the potential separating devices include capacitors connected between a data input and a data output.

18. The data processing system of claim 17, wherein the capacitor is connected to the data output via a threshold value circuit having a high-resistance input.

19. The data processing system of claim 12, wherein the processing of the control information in the receiver units is based on each of the receiver units controlling one of multiple identical devices of the vehicle on the basis of the received control information.

20. The data processing system of claim 19, wherein the identical devices are brakes.

21. The data processing system of claim 20, wherein the receiver units of the brakes of wheels lying diagonally opposite each other on the vehicle are located on the same section of the ring bus.

22. The data processing system of claim 12, wherein at least one gateway which supports the data traffic between the ring bus and a second bus connected to the gateway is among the processing units.
