Vehicle prognostics and remedial response
First Claim
1. A method of carrying out a remedial action in response to a vehicle prognosis, the method comprising:
- receiving vehicle feature data from a vehicle;
extracting a plurality of feature combination data from the vehicle feature data, wherein each of the feature combination data pertains to a feature combination, wherein each of the feature combinations includes two or more vehicle features;
for each extracted feature combination data, then;
evaluating the extracted feature combination data using an anomaly detection function configured particularly for the feature combination, wherein the anomaly detection function is based on a multivariate distribution mixture model; and
obtaining an anomaly detection score for each extracted feature combination based on the evaluating step;
determining a vehicle subsystem that comprises a portion of vehicle electronics installed on the vehicle and that is likely experiencing a problem or unusual behavior based on the anomaly detection scores; and
carrying out a remedial action in response to the determining step.

10. A method of carrying out a remedial action in response to a vehicle prognosis, the method comprising:
-
receiving vehicle feature data from a vehicle, wherein the vehicle feature data includes data for a plurality of vehicle features, and wherein each of the vehicle features are associated with an onboard vehicle sensor; extracting a plurality of feature combination data from the vehicle feature data, wherein each of the feature combination data includes data pertaining to two or more vehicle features; for each extracted feature combination data, obtaining an anomaly detection score for each extracted feature combination based on the evaluating step, wherein the anomaly detection scores are each determined by; obtaining an anomaly detection function for a given feature combination, wherein the anomaly detection function is based on a multivariate distribution model that is specifically generated for the feature combination; and calculating the anomaly detection score based on the anomaly detection function and the extracted feature combination data; determining a vehicle subsystem that comprises a portion of vehicle electronics installed on the vehicle and that is likely experiencing a problem or unusual behavior based on the anomaly detection scores; and carrying out a remedial action in response to the determining step. - View Dependent Claims (11, 12, 13, 14, 15, 16)

17. A remote vehicle prognosis and remediation system, comprising:
-
a server that includes a processor and computer-readable memory, the computer-readable memory storing a computer program; and a vehicle prognostics database that stores vehicle telemetry information including a plurality of anomaly detection functions; wherein the computer program, when executed by the processor, causes the server to; receive vehicle feature data from a vehicle; extract a plurality of feature combination data from the vehicle feature data, wherein each of the feature combination data pertains to a feature combination, wherein each of the feature combinations includes two or more vehicle features; for each extracted feature combination data, then; evaluate the extracted feature combination data using an anomaly detection function configured particularly for the feature combination, wherein the anomaly detection function is based on a multivariate mixture model; and obtain an anomaly detection score for each extracted feature combination based on the evaluating step; determine a vehicle subsystem that comprises a portion of vehicle electronics installed on the vehicle and that is likely experiencing a problem or unusual behavior based on the anomaly detection scores; and carry out a remedial action in response to the determining step.
