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 electronic 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,

wherein the control device is configured for switching over from a control signal receiving status into a data transmitting operating state for outputting data via the operator control element termination, and

wherein the control device is assigned to a motor vehicle component selected from the group consisting of:

a power window lifter,

a sliding/tilting sunroof drive,

a motor-driven vehicle door or sliding door, and

a motor-driven tailgate or trunk lid.

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 3, 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 an input amplifier.

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

7. 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.

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

9. 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.

10. The arrangement according to claim 9, 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.

11. The arrangement according to claim 9, 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.

12. 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.

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

14. An arrangement for transmitting data between an electronic 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,

wherein the diagnostic device has a signal equalization module configured to provide Viterbi signal equalization.

15. A system comprising:

a diagnostic device, and

a control device comprising;

at least one operator control element termination configured for communicative connection to the diagnostic device,

a switchover module configured to switch from a control signal receiving status to a data transmitting operating state for communicating data to the diagnostic device via the operator control element termination,

wherein the control device is assigned to a motor vehicle component selected from the group consisting of;

a power window lifter,

a sliding/tilting sunroof drive,

a motor-driven vehicle door or sliding door, and

a motor-driven tailgate or trunk lid.

16. A control device for an arrangement according to claim 15, wherein the switchover module is configured to switch from the control signal receiving status to the data transmitting operating state in response to a predefined switchover signal received from the diagnostic device.

17. An electronic control device configured for switching between operating states, the electronic control device comprising:

a computing unit connected to an operator control element termination for applying operation signals, and

a removable operator control element connected to the operator control element termination,

wherein the electronic control device is configured to switch over from a control signal receiving state into a data transmitting operating state for outputting data from the computing unit via the operator control element termination to a diagnostic device, while the operator control element is removed from the operator control element termination.
