Abstract

A data recording device for recording communication data in a vehicle network includes a first input for receiving first communication data from a first point in the vehicle network and a second input for receiving second communication data from a second point in the vehicle network. The data recording device provides the first communication data with a first time stamp and the second communication data with a second time stamp. The first time stamp and the second time stamp are synchronized with one another.

Claims

1-10. -10. (canceled)

11. A data recording device (22) for recording communication data in a vehicle network (10), the data recording device (22) comprising:

a first input (24a) configured to receive first communication data from a first point (18, 16) in the vehicle network (10); and

a second input configured to receive second communication data from a second point (18, 16) in the vehicle network (10),

wherein the data recording device (22) is configured to provide the first communication data with a first time stamp and to provide the second communication data with a second time stamp, the first time stamp and the second time stamp being synchronized with one another.

12. The data recording device (22) as claimed in claim 11, wherein the data recording device (22) configured to temporally organize the first communication data and the second communication data using the first and second time stamps.

13. The data recording device (22) as claimed in claim 11, wherein the vehicle network (10) has Ethernet connections;

the first communication data and the second communication data having Ethernet data packets.

14. The data recording device (22) as claimed in claim 11, further comprising:

a synchronization input (34) configured to synchronize the data recording device (22) with a further data recording device, such that the first and second time stamps are synchronized with time stamps of the further data recording device.

15. The data recording device (22) as claimed in claim 11, the data recording device being implemented using hardware.

16. A diagnostic arrangement (20) for a vehicle, comprising:

a vehicle network (10) for a vehicle, the network having a plurality of electronic components (14) and a plurality of network connections (16) which connect the electronic components (14); and

a data recording device (22) as claimed in claim 11.

17. The diagnostic arrangement (20) as claimed in claim 16, wherein the first input (24a) of the data recording device (22) is connected to an output of a network switch (18).

18. The diagnostic arrangement as claimed in claim 16, wherein the first input (24a) of the data recording device (22) is connected to a network line (16) by a tap (26).

19. A method for recording communication data in a vehicle network (10), the method comprising:

receiving, in a data recording device (22), first communication data from a first point (16, 18) in the vehicle network (10);

receiving, in the data recording device (22), second communication data from a second point (16, 18) in the vehicle network (10);

providing the first communication data with a first time stamp in the data recording device (22); and

providing the second communication data with a second time stamp in the data recording device (22), the first time stamp and the second time stamp being synchronized with one another.

20. The method as claimed in claim 19, further comprising:

synchronizing the data recording device (22) with a further data recording device.
