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

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 for an analysis of the status message; and

receiving a transmitting message based on the analysis of the status message by a receiving device.

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

detecting a user authorization input and transmitting a status message to a vehicle-external server as a function of the detected user authorization input.

3. 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.

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

5. The diagnostic method as recited in claim 2, 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.

6. The diagnostic method as recited in claim 2, 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.

7. The diagnostic method as recited in claim 2, 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.

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

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

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

10. The diagnostic device as recited in claim 8, wherein a central diagnostic device is provided which is connected to the detection unit with the aid of a bus.

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

12. 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, 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;

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

a receiving device.

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

14. 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;

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 for an analysis of the status message; and

receiving a transmitting message based on the analysis of the status message by a receiving device.
