Abstract

In a system for testing a control unit system having at least one control unit and at least one sensor, the control unit and sensor and possible other bus users being connected to one another via a data bus, and a test signal being fed into one of the bus users for testing the control unit system, at least one of the bus users, in particular a sensor, is replaced by a corresponding emulator of this bus user.

Claims

1-16. -16. (canceled)

17. A system for testing a control unit system, the control unit system having at least one control unit and at least one sensor, the control unit and the sensor being connected to one another via a data bus, the system for testing comprising:

an arrangement adapted to feed a test signal into a bus user for testing the control unit system; and

at least one emulator of the bus user.

18. The system as recited in claim 17, wherein other bus users are connected to the bus.

19. The system as recited in claim 17, wherein the bus user into which the test signal is fed is the emulator.

20. The system as recited in claim 19, wherein the emulator emulates the sensor.

21. The system as recited in claim 17, wherein the emulator has a scanner function to detect data from other bus users.

22. The system as recited in claim 17, further comprising:

a computer for data transmission and control information, the computer having an interface to the emulator.

23. The system as recited in claim 17, wherein the emulator is adapted to process at least one of digital and analog output quantities.

24. The system as recited in claim 17, wherein the emulator is adapted to output at least one of digital and analog output quantities.

25. The system as recited in claim 17, wherein the emulator has different processing levels including levels responsible for at least one of signal processing and filtering which correspond to the emulated bus user.

26. The system as recited in claim 17, wherein the emulator includes an individually useable processing level which replaces a processing level responsible for coupling the emulated bus user to the control unit.

27. A method for testing a control unit system having at least one control unit and at least one sensor, the control unit and the sensor being connected to one another via a data bus, the method comprising:

emulating, by an emulator, a bus user; and

a feeding test signal being fed into a bus user of the data bus for testing the control unit system.

28. The method as recited in claim 27, wherein other bus users are connected to the data bus.

29. The method as recited in claim 27, wherein the bus user into which the test signal is fed is the emulator.

30. The method as recited in claim 29, wherein the emulator emulates the sensor of the control unit system.

31. The method as recited in claim 27, further comprising:

scanning, by the emulator, to detect data of other bus users.

32. The method as recited in claim 27, further comprising:

transmitting data and control information into the emulator via a computer.

33. The method as recited in claim 27, further comprising:

feeding at least one of digital and analog input quantities into the emulator.

34. The method as recited in claim 27, further comprising:

outputting at least one of digital and analog output quantities by the emulator.
