Abstract

To transmit data between an electric control unit (3) that has at least one operator element connection (6; 6.1, 6.2) and a diagnostic unit (7), the diagnostic unit (7) is designed to be connected to the operator element connection (6; 6.1, 6.2) and the control unit (3) is designed to switch over (17) from an operating signal receiving status into a data transmission mode in order to deliver data via the operator element connection.

Claims

1. An arrangement for transmitting data between an electric control device comprising at least one operator control element termination and a diagnostic device, wherein the diagnostic device is configured for connecting to the operator control element termination, and the control device is configured for switching over from a control signal receiving status into a data transmitting operating state for the purpose of outputting data via the operator control element termination.

2. The arrangement according to claim 1, wherein the control device has a communication module to enable communication with the diagnostic device.

3. The arrangement according to claim 1, wherein the control device has an operating state switchover module responding to a predefined switchover signal of the diagnostic device.

4. The arrangement according to claim 1, wherein the operating state switchover module has a detector detecting a predefined signal pattern and a switching module connected thereto.

5. The arrangement according to claim 1, wherein the diagnostic device has a signal equalization module, e.g. having Viterbi signal equalization.

6. The arrangement according to claim 1, wherein the diagnostic device has an input amplifier.

7. The arrangement according to claim 1, wherein the diagnostic device has a clock signal recovery unit.

8. The arrangement according to claim 1, wherein the diagnostic device has an operator control element corresponding to the operator control element of the control device.

9. The arrangement according to claim 1, comprising a single-channel connection between control device and diagnostic device in the form of a half- or preferably full-duplex connection.

10. The arrangement according to claim 1, comprising a two-channel connection between the control device having two operator control element terminations and the diagnostic device.

11. The arrangement according to claim 10, wherein one channel is provided for transmitting control commands from the diagnostic device to the control device and the other channel is provided for transmitting diagnostic data.

12. The arrangement according to claim 10, wherein one channel is provided for transmitting control commands from the diagnostic device to the control device as well as diagnostic data from the control device to the diagnostic device and the other channel is provided for clock signal transmission.

13. The arrangement according to claim 1, wherein in the case of an available bus termination of the control device a bus connection serving for the transmission of control commands is provided between the diagnostic device and the control device.

14. The arrangement according to claim 1, wherein the control device is assigned to a motor vehicle.

15. The arrangement according to claim 14, wherein the control device is assigned to a power window lifter.

16. The arrangement according to claim 14, wherein the control device is assigned to a sliding/tilting sunroof drive.

17. The arrangement according to claim 14, wherein the control device is assigned to a motor-driven vehicle door or sliding door.

18. The arrangement according to claim 14, wherein the control device is assigned to a motor-driven tailgate or trunk lid.

19. The arrangement according to claim 1, wherein the control device has an operator pushbutton or switch block as operator control element.

20. A system comprising a control device and an arrangement according to claim 1, the control device comprising at least one operator control element termination, and a communication module to enable communication with an external diagnostic device.

21. A control device for an arrangement according to claim 1 wherein the control device comprises an operating state switchover module responding to a predefined switchover signal of the diagnostic device.

22. The control device according to claim 21, wherein the operating state switchover module has a detector detecting a predefined signal pattern and a switching module connected thereto.

23. A system comprising a control device and an arrangement according to claim 18, wherein the control device comprises an operating state switchover module responding to a predefined switchover signal of the diagnostic device.

24. The control device according to claim 23, wherein the operating state switchover module has a detector detecting a predefined signal pattern and a switching module connected thereto.
