Abstract

A method for the diagnosis and/or configuration of a vehicle includes sending, by a back end unit via an air interface to a vehicle unit, a data packet which comprises an order for the diagnosis and/or configuration of the vehicle, evaluating, by the vehicle unit, whether the diagnosis and/or a configuration of the vehicle is to be undertaken, and initiating, by the vehicle unit, the diagnosis and/or a configuration of the vehicle.

Claims

1. A computer-implemented method for conducting a diagnosis of a vehicle or a configuration of a vehicle, the method comprising:

wireless receiving by the vehicle a data packet which comprises an order to conduct the diagnosis or the configuration of the vehicle and a runtime executable script, which when executed, causes the diagnosis or the configuration of the vehicle to be performed according to the order,

evaluating the data packet to determine whether the diagnosis and/or the configuration of the vehicle is to be undertaken, and

initiating the diagnosis or the configuration of the vehicle by executing the runtime executable script.

2. The method as claimed in claim 1,

wherein the method conducts the configuration of the vehicle,

wherein the data packet further contains software for the configuration of the vehicle, and

and wherein the method further comprises interpreting the runtime executable script to determine instructions for installing the software and executing the instructions to install the software in the vehicle.

3. The method as claimed in claim 1, wherein, in the vehicle, additional runtime executable scripts for the diagnosis or the configuration of the vehicle are stored.

4. The method as claimed in claim 1, wherein diagnostic data, which is used when executing the runtime executable script for the diagnosis or configuration of the vehicle, is stored in the vehicle.

5. The method as claimed in claim 1, wherein in the vehicle, during the execution of the runtime executable script for the diagnosis or the configuration of the vehicle, logging files for documentation are generated and stored.

6. The method as claimed in claim 1, wherein documentation data of the diagnosis or the configuration of the vehicle performed is wirelessly transmitted for storage.

7. The method of claim 6, wherein the documentation data comprises at least one of error information corresponding to an error state of the vehicle or measurement values corresponding to measurements made during the diagnosis or the configuration of the vehicle.

8. The method of claim 6, wherein the documentation data comprises sequence protocol data corresponding to an actual sequence of the execution of the runtime executable script.

9. The method of claim 1, wherein the order of the packet is a data structure representing information and data which defines the diagnosis and/or the configuration of a vehicle.

10. The method of claim 9, wherein the order further comprises meta information comprising at least one of an identification of the order, a priority for the execution of the order, a duration of the order, a periodicity of the order, or trigger conditions for executing the order.

11. The method of claim 9, wherein the order further comprises processing instructions comprising at least one of a precondition test sequence, an execution sequence, or a post-processing sequence.

12. The method of claim 1, the method further comprising interpreting the runtime executable script, the runtime executable script being based on the Open Test Sequence Exchange standard, wherein the execution of the runtime executable script is based on the interpreting method step.

13. The method of claim 1,

wherein the method conducts the diagnosis of the vehicle, the order is to conduct the diagnosis of the vehicle, and the runtime executable script, when executed causes the diagnosis of the vehicle to be performed according to the order,

wherein the data packet is evaluated to determine whether the diagnosis of the vehicle is to be undertaken, and

wherein the diagnosis of the vehicle is initiated by executing the runtime executable script.

14. The method of claim 13, the method further comprising:

determining an identifier corresponding to a vehicle telemetry by executing the runtime readable script,

determining a description of an inquiry for determining a value for the vehicle telemetry based on the identifier,

performing the inquiry to receive the value, and

storing the value.

15. The method of claim 1, wherein the method conducts the configuration of the vehicle, wherein the order is to conduct the configuration of the vehicle, wherein the runtime executable script, when executed, causes the configuration of the vehicle to be performed according to the order, wherein the evaluating of the data packet determines that the configuration is to be undertaken, and the configuration is initiated by executing the runtime executable script.

16. The method of claim 1, wherein the data packet is a data structure comprising at least two sub-packets of data, a first sub-packet containing data representing the order and a second sub-packet containing data representing the runtime executable script, wherein the order defines how and what configuration and/or diagnosis is performed.

17. A back end unit in wireless communication with a vehicle, the back end unit comprising a processor and a memory storing processor executable instructions, which when executed by the processor cause the back end unit to:

generate a data packet which, comprises an order for conducting a diagnosis on the vehicle or a configuration of the vehicle and comprises a runtime executable script, which when executed, causes the diagnosis or the configuration of the vehicle to be performed according to the order; and

wirelessly send the data packet to the vehicle.

18. The back end unit as claimed in claim 17,

wherein the order is for conducting the configuration of a vehicle,

wherein the data packet further comprises software for the configuration of the vehicle, and

and wherein the runtime executable script is configured such that, when interpreted and then executed by the vehicle, the runtime executable script causes the vehicle to install the software.

19. A vehicle unit of a vehicle in wireless communication with a back end system external to the vehicle, the vehicle unit comprising a processor and a memory storing processor executable instructions, which when executed by the processor cause the vehicle unit to:

wirelessly receive a data packet, which includes an order for conducting a diagnosis of the vehicle or a configuration of the vehicle and comprises a runtime executable script, which when executed, causes the diagnosis or the configuration of the vehicle to be performed according to the order,

evaluate the data packet to determine whether the diagnosis or the configuration of the vehicle is to be undertaken, and

execute the runtime executable script to initiate the diagnosis or the configuration of the vehicle.

20. A system for conducting a diagnosis or a configuration of a vehicle, the system comprising:

a back end unit in wireless communication with a vehicle unit, the back end unit comprising a processor and a memory storing instructions, which when executed by the processor of the back end unit cause the back end unit to;

generate a data packet which comprises an order for conducting the diagnosis on the vehicle or the configuration of the vehicle and comprises a runtime executable script, which when executed, causes the diagnosis or the configuration of the vehicle to be performed according to the order; and

wirelessly send the data packet to the vehicle unit, and

the vehicle unit in wireless communication with the back end unit, the vehicle unit comprising a processor and a memory instructions, which when executed by the processor cause the back end unit to;

receive the data packet,

evaluate the data packet to determine whether the diagnosis or the configuration of the vehicle is to be undertaken, and

execute the runtime executable script to initiate the diagnosis or the configuration of the vehicle.
