Abstract

Embodiments of techniques or systems for customization of, diagnostic assistance, and driving analytics related to snapshot data of a vehicle are provided herein. For example, a snapshot can be taken. The snapshot can be based on a snapshot package customized according to symptoms experienced by a driver of a vehicle, and analyzed individually or in conjunction with other snapshots to determine a trend. Additionally, the snapshot can be based on a configuration of a vehicle. In this scenario, the snapshot and the configuration of the vehicle can be used to provide an enhanced troubleshooting guide by removing non-suspect areas from consideration, thereby mitigating troubleshooting time. The snapshot can be setup to record parameters related to wear and tear on components of the vehicle. Suggestions can be made to a driver of the vehicle to reduce or mitigate actions that negatively impact wear and tear.

Claims

1. A method for customizing diagnostic assistance, comprising:

receiving, by a system comprising a processing unit, a snapshot package that comprises a trigger condition and a set of parameters customized for a vehicle and a vehicle symptom; and

taking, by the system, a snapshot based on a determination that the trigger condition has occurred, the snapshot package, and a configuration of the vehicle that is indicative of relationships between associated components of the vehicle, the taking the snapshot comprises recording the set of parameters from the associated components of the vehicle the associated components comprise

a first component that contributes to the vehicle symptom and at least a second component that does not contribute to the vehicle symptom, and wherein the taking the snapshot based on the trigger condition and the set of parameters comprises mitigating an amount of storage space used for snapshot data based on not taking another snapshot of another set of parameters that are not related to the associated components.

2. The method of claim 1, wherein the trigger condition comprises a diagnostic trouble code.

3. The method of claim 1, further comprising generating, by the system, custom diagnostic assistance based on the snapshot.

17. The method of claim 1, further comprising developing, by the system, at least one trend based on the set of parameters, wherein the at least on trend indicates an issue related to a geographic region in which the vehicle is operated.

18. The method of claim 1, further comprising utilizing, by the system, parameters of the second component to facilitate troubleshooting the vehicle symptom.

4. A system for customizing diagnostic assistance, comprising:

a processor that executes the following computer executable components stored in a memory;

a controller area network that receives an indication of an occurrence of a trigger and a snapshot package that comprises a set of parameters determined based on a vehicle and symptoms exhibited by the vehicle, a first duration during which to record a first parameter of the set of parameters, and at least a second duration, different from the first duration, during which to record at least a second parameter of the set of parameters; and

a snapshot component that obtains a snapshot based on the occurrence of the trigger, the snapshot package, and a configuration of a vehicle,

wherein the configuration of the vehicle is indicative of relationships between components of the vehicle, and the snapshot component records respective parameters of the set of parameters from a component that initiated the trigger and one or more associated components based on the relationships, and wherein the set of parameters is selected such that the snapshot component mitigates storage space usage and does not obtain another snapshot of another set of parameters from other components determined not to be associated with the component that initiated the trigger.

5. The system of claim 4, further comprising an interface component that transmits the snapshot to a third party.

6. The system of claim 4, further comprising an analysis component that generates a custom diagnostic assistance guide based on the snapshot.

7. The system of claim 4, further comprising an analysis component that generates an event report comprising a summary of the set of parameters.

8. The system of claim 4, further comprising a storage component that stores the snapshot package and a diagnostic trouble code.

19. The method of claim 4, wherein the duration during which to record the set of parameters is configured to enhance a granularity level of the set of parameters.

20. The method of claim 4, wherein the duration during which to record the set of parameters is different for each parameter of the set of parameters.

9. A method for customizing diagnostic assistance, comprising:

receiving, at a system comprising a processing unit, a snapshot comprising a set of parameters from a first component and at least a second component of a vehicle based on a snapshot package that defines the set of parameters based on symptoms exhibited by the vehicle and a configuration of the vehicle;

identifying, by the system, a first area associated with the first component and a second area associated with the second component;

receiving, by the system, a set of diagnostic assistance suggestions associated with the first area and the second area;

classifying, by the system, the first area as suspect based on a determination that the symptom is associated with the first area based on the set of parameters, and the second area as non-suspect based on another determination that the symptom is not associated with the second area based on the set of parameters; and

providing, by the system, a subset of the diagnostic assistance suggestions based on the classifying,

wherein the configuration of the vehicle is indicative of one or more relationships between components of the vehicle and defines the first component and at least the second component as related components, and wherein the set of parameters are associated with the first component and at least the second component and are selected to mitigate an amount of storage space used to record the snapshot.

10. The method of claim 9, further comprising selecting, by the system, the set of parameters based on the one or more relationships between components of the vehicle.

11. The method of claim 9, further comprising determining, by the system, the subset of the diagnostic assistance suggestions by removing one or more diagnostic assistance suggestions for the second area classified as non-suspect.

12. The method of claim 9, further comprising receiving, by the system, the set of diagnostic assistance suggestions from a diagnostic assistance library.

13. The method of claim 9, wherein a diagnostic assistance suggestion of the subset of the diagnostic assistance suggestions comprises an instruction to inspect the first area classified as suspect.

14. The method of claim 9, further comprising generating, by the system, an event report comprising a summary of one or more of the parameters.

15. The method of claim 9, wherein the snapshot comprises a snapshot window that defines a configurable duration during which the set of parameters are recorded.

16. The method of claim 15, wherein the configurable duration increases a level of granularity associated with the set of parameters.
