Abstract

A diagnostic method for a vehicle component of a vehicle, an operating parameter of the vehicle component being detected during an operation of the vehicle and a status message corresponding to a status of the vehicle component being transmitted to a vehicle-external server as a function of the detected operating parameter for an analysis of the status message, a message based on the analysis of the status message being transmitted to a receiving device. The invention furthermore relates to a corresponding diagnostic device, a corresponding diagnostic system, as well as a computer program is also described.

Claims

1. A diagnostic method for a vehicle component of a vehicle, comprising:

detecting, by a detection device, an operating parameter of the vehicle component during an operation of the vehicle;

detecting, by a second detection device, a user authorization input;

transmitting, by a transmitting device, a status message corresponding to a status of the vehicle component to a vehicle-external server as a function of the detected operating parameter and the detected user authorization input for an analysis of the status message; and

receiving a transmitting message from the vehicle-external server, based on the analysis of the status message, by a receiving device, wherein the receiving device is one of (i) a second vehicle-external server different from the vehicle-external server, (ii) a device that is vehicle-internal to the vehicle, or (iii) a mobile phone;

wherein the transmitting message, which is received from the vehicle-external server, is a message which is transmitted to a repair facility.

2. The diagnostic method as recited in claim 1, further comprising:

detecting a variation over time of the operating parameter and a deviation of the operating parameter from a setpoint operating parameter value, wherein a status message is transmitted to a vehicle-external server as a function of the deviation.

3. The diagnostic method as recited in claim 1, wherein the operating parameter includes an intervention intensity of an actuator of the vehicle component.

4. The diagnostic method as recited in claim 1, wherein the operating parameter and the status message are transmitted to a vehicle-internal central communication device of the vehicle for the transmission of the operating parameter and the status message to the vehicle-external server.

5. The diagnostic method as recited in claim 1, wherein a particular operating parameter is detected by other different vehicle components and a substatus message corresponding to a particular state of the other vehicle components is transmitted in each case as a function of the detected operating parameters to a central vehicle-internal diagnostic device, which transmits the status message to the vehicle-external server as a function of the transmitted substatus message.

6. The diagnostic method as recited in claim 1, wherein the receiving device is included in a repair facility which is readied in repair mode for a repair of the vehicle component at a predetermined point in time as a function of the message and as a function of a detected additional user authorization input.

14. The diagnostic method of claim 1, wherein the receiving device is the second vehicle-external server, the second vehicle-external server being remote from the vehicle-external server.

15. The diagnostic method of claim 1, wherein the receiving device is vehicle-internal to the vehicle.

16. The diagnostic method of claim 1, wherein the receiving device is a mobile phone which receives the transmitting message wirelessly.

20. The diagnostic method of claim 1, wherein the receiving device is included in the repair facility which is readied in repair mode for a repair of the vehicle component at a predetermined point in time as a function of the message and as a function of a detected additional user authorization input.

21. The diagnostic method of claim 1, wherein preparation of the repair facility is carried out as a function of the message, and wherein the message is based on the analysis of the status message, so that knowledge is gained regarding which repair measures must be carried out, so that the repair facility may be readied in a repair mode.

7. A diagnostic device for a vehicle component of a vehicle, comprising:

a detection device to detect an operating parameter of the vehicle component;

a second detection device to detect a user authorization input;

a transmitting device to transmit a status message corresponding to a status of the vehicle component to a vehicle-external server for an analysis of the status message, the transmission of the status message being carried out as a function of the detected operating parameter and the detected user authorization input; and

a receiving device to receive a transmitting message from the vehicle external server, the transmitting message being based on the analysis of the status message, the receiving device being a vehicle-internal device of the vehicle;

wherein the transmitting message, which is received from the vehicle-external server, is a message which is transmitted to a repair facility.

8. The diagnostic device as recited in claim 7, wherein the detection device is integrated into a control unit of the vehicle component.

9. The diagnostic device as recited in claim 7, wherein a central diagnostic device is provided which is connected to the detection unit with the aid of a bus.

10. The diagnostic device as recited in claim 9, wherein the central diagnostic device is integrated into a central communication device including the transmitting device.

11. A diagnostic system for a vehicle component of a vehicle, comprising:

a diagnostic device for the vehicle component, the diagnostic device including a detection device to detect an operating parameter of the vehicle component, a second detection device to detect a user authorization input, and a transmitting device to transmit a status message corresponding to a status of the vehicle component to a vehicle-external server for an analysis of the status message, the transmission of the status message being carried out as a function of the detected operating parameter and the detected user authorization input;

the vehicle-external server for an analysis of the status message; and

a receiving device to receive a transmitting message from the vehicle external server, the transmitting message being based on the analysis of the status message, wherein the receiving device is one of (i) a second vehicle-external server different from the vehicle-external server, (ii) a device that is vehicle-internal to the vehicle, or (iii) a mobile phone;

wherein the transmitting message, which is received from the vehicle-external server, is a message which is transmitted to a repair facility.

12. The diagnostic system as recited in claim 11, wherein the receiving device is included in the repair facility.

17. The diagnostic system of claim 11, wherein the receiving device is the second vehicle-external server, the second vehicle-external server being remote from the vehicle-external server.

18. The diagnostic system of claim 11, wherein the receiving device is vehicle-internal to the vehicle.

19. The diagnostic system of claim 11, wherein the receiving device is a mobile phone which receives the transmitting message wirelessly.

13. A computer readable storage medium storing a computer

program including program code for diagnosing a vehicle component of a vehicle, the program code, when executed by a computer, causing the computer to perform the steps of:

detecting an operating parameter of the vehicle component during an operation of the vehicle;

detecting a user authorization input;

transmitting a status message corresponding to a status of the vehicle component to a vehicle-external server as a function of the detected operating parameter and the detected user authorization input for an analysis of the status message; and

receiving a transmitting message from the vehicle-external server, based on the analysis of the status message, by a receiving device that is vehicle-internal to the vehicle;

wherein the transmitting message, which is received from the vehicle-external server, is a message which is transmitted to a repair facility.
