Abstract

A cloud-based server is communicatively coupled to vehicle computing devices and is programmed to receive a first fault message transmitted from a first vehicle, the first fault message providing data to indicate an unsuccessful performance of a first diagnostic test, such as an onboard diagnostic (OBD) test, in the first vehicle and one or more vehicle operating conditions during the unsuccessful performance of the first diagnostic test in the first vehicle. The server is further programmed to determine, from the one or more vehicle operating conditions, one or more required conditions for an expected successful performance of the first diagnostic test and generate a first performance message to communicate the one or more required conditions for the expected successful performance of the first diagnostic test.

First claim

What is claimed is:

1 . A method, comprising:
receiving a first fault message transmitted from a first vehicle, the first fault message providing data to indicate an unsuccessful performance of a first diagnostic test in the first vehicle and one or more vehicle operating conditions during the unsuccessful performance of the first diagnostic test in the first vehicle; determining, from the one or more vehicle operating conditions, one or more required conditions for an expected successful performance of the first diagnostic test; and generating a first performance message, the first performance message providing data to indicate the one or more required conditions for the expected successful performance of the first diagnostic test.

2 . The method of claim 1 , further comprising:
receiving a second fault message transmitted from a second vehicle, the second fault message providing data to indicate an unsuccessful performance of the first diagnostic test in the second vehicle and one or more vehicle operating conditions during the unsuccessful performance of the first diagnostic test in the second vehicle; and updating, based on the second fault message, the one or more required conditions for the expected successful performance of the first diagnostic test.

3 . The method of claim 1 , further comprising:
receiving a second fault message transmitted from the first vehicle, the second fault message providing data to indicate an unsuccessful performance of a second diagnostic test in the first vehicle and one or more vehicle operating conditions during the unsuccessful performance of the second diagnostic test in the first vehicle; determining, from the second test report message, one or more required conditions for an expected successful performance of the second diagnostic test; and generating a second performance message, the second performance message providing data to indicate the one or more required conditions for the expected successful performance of the second diagnostic test.

4 . The method of claim 1 , wherein the one or more required conditions include at least one of an environmental condition and a vehicle path condition.

5 . The method of claim 1 , wherein determining the one or more required conditions includes modeling the expected successful performance of the first diagnostic test with one of a support vector machine, neural net, and clustering algorithm.

6 . The method of claim 1 , wherein the first diagnostic test is an onboard diagnostic (OBD) test.

7 . A method comprising:
determining that current vehicle operating conditions of a vehicle meet stored entry conditions for initializing a first diagnostic test, the first diagnostic test having a first duration; determining expected vehicle operating conditions of the vehicle for the first duration; querying a remote computing device for a first performance message; receiving the first performance message, the first performance message providing data to indicate one or more required conditions for an expected successful performance of the first diagnostic test; comparing the expected vehicle operating conditions of the vehicle for the first duration to the one or more required conditions from the first performance message; and determining, based on the comparison, whether to perform the first diagnostic test.

8 . The method of claim 7 , further comprising:
determining an unsuccessful performance of the first diagnostic test; generating a fault message, the fault message providing data to indicate the unsuccessful performance of the first diagnostic test and one or more vehicle operating conditions during the unsuccessful performance of the first diagnostic test; and transmitting the fault message to the remote computing device.

9 . The method of claim 7 , wherein the one or more required conditions include at least one of an environmental condition and a vehicle path condition.

10 . The method of claim 7 , wherein the first diagnostic test is an onboard diagnostic (OBD) test.

11 . The method of claim 7 , wherein the remote computing device is a cloud-based server.

12 . A system, comprising:
a computer comprising a processor and a memory, the memory storing instructions executable by the processor to: receive a first fault message transmitted from a first vehicle, the first fault message providing data to indicate an unsuccessful performance of a first diagnostic test and one or more vehicle operating conditions during the unsuccessful performance of the first diagnostic test; determine, from the one or more vehicle operating conditions, one or more required conditions for an expected successful performance of the first diagnostic test; and generating a first performance message, the first performance message providing data to indicate the one or more required conditions for the expected successful performance of the first diagnostic test.

13 . The system of claim 12 , wherein the memory stores further instructions executable by the processor to:
receive a second fault message transmitted from a second vehicle, the second fault message providing data to indicate an unsuccessful performance of the first diagnostic test in the second vehicle and one or more vehicle operating conditions during the unsuccessful performance of the first diagnostic test in the second vehicle; and update, based on the second fault message, the one or more required conditions for the expected successful performance of the first diagnostic test.

14 . The system of claim 12 , wherein the memory stores further instructions executable by the processor to:
receive a second fault message from the first vehicle, the second fault message providing data to indicate an unsuccessful performance of a second diagnostic test in the first vehicle and one or more vehicle operating conditions during the unsuccessful performance of the second diagnostic test in the first vehicle; determine, from the second fault message, one or more required conditions for an expected successful performance of the second diagnostic test; and generating a second performance message, the second performance message providing data to indicate the one or more required conditions for the expected successful performance of the second diagnostic test.

15 . The system of claim 12 , wherein the one or more required conditions for the expected successful performance of the first diagnostic test include at least one of an environmental condition and a vehicle path condition.

16 . The system of claim 15 , where the environmental condition is one of an ambient temperature and a precipitation condition.

17 . The system of claim 15 , wherein the vehicle path condition is one of a vehicle acceleration and a vehicle deceleration.

18 . The system of claim 12 , wherein determining the one or more required conditions for the expected successful performance of the first diagnostic test includes modeling the expected successful performance of the first diagnostic test with one of a support vector machine, neural net, and clustering algorithm.

19 . The system of claim 12 , wherein the first diagnostic test is an onboard diagnostic (OBD) test.

20 . The system of claim 12 , wherein the computer is a cloud-based server.
