Abstract

A method includes collecting state of health (SOH) data and usage data from a plurality of vehicles. A peer group is identified among the vehicles. A vehicle health prognosis is generated for each vehicle of the peer based on the collected SOH and usage data. The vehicles of the peer group are ranked based on the generated vehicle health prognosis and the rank is reported to an output device that is associated with each vehicle or with a user of each vehicle. If evaluation of the ranking indicates that the health prognosis of a vehicle of the peer group is improvable by modifying vehicle usage, an alert is issued to a user of that vehicle.

Claims

1. A method comprising:

collecting state of health (SOH) data related to vehicle SOH from a plurality of vehicles;

collecting usage data related to vehicle usage from the plurality of vehicles;

identifying a peer group among the plurality of vehicles;

generating a vehicle health prognosis for a vehicle of the plurality of vehicles based on the collected SOH and usage data;

ranking the vehicles of the peer group based on the generated vehicle health prognosis for each of the vehicles of the peer group;

reporting the rank of each vehicle of the peer group to an output device that is associated with that vehicle or with a user of that vehicle; and

if evaluation of the ranking indicates that the health prognosis of a vehicle of the peer group is improvable by modifying vehicle usage, issuing an alert.

2. The method of claim 1, wherein the SOH data or the usage data is collected via a network.

3. The method of claim 2, wherein the network is a wireless network.

4. The method of claim 1, wherein identifying the peer group comprises identifying vehicles of the plurality of vehicles that are characterized by a predefined set of one or more characteristics.

5. The method of claim 4, wherein the predefined set of characteristics comprises a characteristic of a component of the vehicle.

6. The method of claim 1, wherein the vehicle health prognosis comprises an estimate of a residual value of the vehicle.

7. The method of claim 1, further comprising reporting the estimated residual value of each vehicle of the peer group to the output device.

8. The method of claim 1, wherein generating a vehicle health prognosis comprises applying a vehicle health model.

9. The method of claim 1, wherein the alert is issued to the to the output device.

10. The method of claim 1, wherein the SOH data comprises data related to a component or system of the vehicle.

11. A system comprising a processor to:

collect data related to a vehicle state of health (SOH) from a plurality of vehicles;

collect data related to vehicle usage from the plurality of vehicles;

identify a peer group among the plurality of vehicles;

generate a vehicle health prognosis for a vehicle of the plurality of vehicles based on the collected SOH and usage data;

rank the vehicles of the peer group based on the generated vehicle health prognosis for each of the vehicles of the peer group;

report the rank of each vehicle of the peer group to an output device that is associated with that vehicle or with a user of that vehicle; and

if evaluation of the ranking indicates that the health prognosis of a vehicle of the peer group is improvable by modifying vehicle usage, issue an alert.

12. The system of claim 11, comprising a network to enable communication between the processor and said plurality of vehicles.

14. The system of claim 12, wherein the processor is associated with a server of the network.

15. The system of claim 11, wherein the peer group comprises vehicles of the plurality of vehicles that are characterized by a predefined set of characteristics.

16. The system of claim 15, wherein the predefined characteristics include a characteristic of a component of the vehicle.

17. The system of claim 11, wherein the alert is issued to the output device.

13. The system of claim 13, wherein the network is a wireless network.

18. A non-transitory computer readable storage medium having stored thereon instructions that when executed by a processor will cause the processor to perform the method of:

collecting state of health (SOH) data related to vehicle SOH from a plurality of vehicles;

collecting usage data related to vehicle usage from the plurality of vehicles;

identifying a peer group among the plurality of vehicles;

generating a vehicle health prognosis for a vehicle of the plurality of vehicles based on the collected SOH and usage data;

ranking the vehicles of the peer group based on the generated vehicle health prognosis for each of the vehicles of the peer group;

reporting the rank of each vehicle of the peer group to an output device that is associated with that vehicle or with a user of that vehicle; and

if evaluation of the ranking indicates that the health prognosis of a vehicle of the peer group is improvable by modifying vehicle usage, issuing an alert.

19. The non-transitory computer readable medium of claim 18, wherein identifying the peer group comprises identifying vehicles of the plurality of vehicles that are characterized by a predefined set of characteristics.

20. The non-transitory computer readable medium of claim 18, wherein the alert is issued to the to the output device.
