Abstract

A system for the diagnosis of a component of a motor vehicle includes a sever configured to provide at least one test sequence for diagnosing the component and at least one execution parameter allocated to the test sequence. The system also includes a diagnostic device configured to receive at least one test sequence and the at least one execution parameter, and to convert it into a runtime script and execute the runtime script according to the execution parameters. A script generation device is configured to generate the test sequences as OTX script or as ETX script.

Claims

1. A system for the diagnosis of a component of a motor vehicle, the system comprising:

a server configured to separately transmit

at least one test sequence for diagnosing the component, and

at least one execution parameter allocated to the test sequence,

wherein the at least one execution parameter defines a performance during the test sequence,

a diagnostic device configured to

receive and pre-execute the at least one test sequence,

receive the at least one execution parameter separately from and subsequent to the receipt of the at least one test sequence, and

execute, using a script execution device, the received at least one test sequence according to the execution parameter.

2. The system according to claim 1, further comprising:

a script generation device having a script input device, which is configured to compile a platform-independent output script.

3. The system according to claim 1, wherein the server and the diagnostic device are connected to each other via a communication means.

4. The system according to claim 3, wherein the communication means is a mobile telephony connection, a satellite connection, or another wireless communication connection.

5. The system according to claim 1, wherein the diagnostic device is part of a telematics platform in a vehicle or in a mobile testing device.

6. The system according to claim 1, wherein the at least one test sequence is a pre-compiled test sequence.

7. The system according to claim 6, wherein the at least one test sequence is Open Test sequence data eXchange (OTX) scripts and the pre-compiled test sequence is executable test sequence exchange scripts.

8. The system according to claim 6, further comprising:

an allocation device configured to allocate the at least one execution parameter to the at least one test sequence or the pre-compiled test sequence.

9. The system according to claim 6, wherein the at least one test sequence is at least one platform-independent test sequence, the pre-complied test sequence is a platform-independent, pre-complied test sequence, the diagnostic device includes a script execution device configured as a script interpreter or a script compiler, wherein the script execution device is configured to generate a platform-adapted runtime script from the at least one platform-independent test sequence, or the platform-independent, pre-compiled test sequence.

10. The system according to claim 9, wherein the diagnostic device includes an execution control device configured to evaluate the execution parameter allocated to the platform-adapted runtime script and to control the execution of the runtime script based on the execution parameter.

11. The system according to claim 1, wherein the diagnostic device is part of a vehicle and the server is external to the vehicle.

12. A method for the diagnosis of a component of a vehicle, the method comprising:

compiling, by a script input device, a platform-independent test sequence;

transmitting, by a transmission device to a server, the platform-independent test sequence;

allocating, by an allocation device, at least one execution parameter to the platform-independent test sequence, wherein the at least one execution parameter defines a performance during the platform-independent test sequence;

receiving and pre-executing, by a diagnostic device from the server, the platform-independent test sequence;

receiving, by the diagnostic device, the execution parameter separately from and subsequent to the receipt of the platform-independent test sequence; and

executing, by the diagnostic device, the platform-independent test sequence according to the execution parameter.

13. The method according to claim 12, wherein the test sequence is pre-complied by a script generation device.

14. The method according to claim 13, further comprising:

transmitting execution results of a script to the server after execution of the platform-independent test sequence.
