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:

using a processor linked with a network to;

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

collect usage 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 each vehicle of the peer group based on the SOH and the usage data;

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

report the ranking through an output device associated with a respective vehicle of the peer group or with a its user, the output device selected from the group consisting of visual output device, audio output device, and tactile output device; and

issue an alert through the output device associated with any of the vehicles of the peer group whose future state of health being improvable through vehicle usage modification.

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

3. The method of claim 2, wherein the predefined set of characteristics comprises a characteristic of a component of the vehicle.

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

5. The method of claim 4, further comprising reporting the estimated residual value of each vehicle of the peer group to the output device.

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

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

8. A system for evaluating vehicular health, the system comprising:

a processor linked with a network, the processor configured 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 each vehicle of the peer group based on the collected S0H and the usage data;

define a ranking of each of the vehicles of the peer group on a basis of the generated vehicle health prognosis for each of the vehicles of the peer group;

report the ranking to an output device associated with a respective vehicle of the peer group or with its user, the output device selected from the group consisting of visual output device, audio output device, and tactile output device; and

issue an alert through the output device associated with any of the vehicles of the peer group whose future state of health being improvable through vehicle usage modification.

9. The system of claim 8, wherein the network is a wireless network.

10. The system of claim 8, wherein the processor is associated with a server of the network.

11. The system of claim 8, wherein the peer group comprises vehicles of the plurality of vehicles that are characterized by a predefined set of characteristics.

12. The system of claim 11, wherein the predefined characteristics include a characteristic of a component of the vehicle.

13. A non-transitory computer readable storage medium having stored thereon instructions that when executed by a processor will cause the processor to perform a 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 each of the vehicles of the peer group based on the collected SOH and usage data;

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

reporting the ranking through an output device associated with a respective vehicle of the peer group or with its user, the output device selected from the group consisting of visual output device, audio output device, and tactile output device of that vehicle; and

issuing an alert through the output device associated with any of the vehicles of the peer group whose future state of health being improvable through vehicle usage modification.

14. The non-transitory computer readable medium of claim 13, wherein identifying the peer group comprises identifying vehicles of the plurality of vehicles that are characterized by a predefined set of characteristics.
