System, method, and apparatus for managing vehicle data collection
A vehicle that includes a policy manager circuit, an endpoint, and a vehicle data interface. The policy manager circuit interprets a data collection policy including a trigger condition and a trigger evaluation data identifier. The endpoint captures a trigger evaluation data stream in response to the trigger evaluation data identifier and the trigger condition. The vehicle data interface receives the trigger evaluation data stream.
1. A vehicle comprising:
a policy manager circuit configured to interpret a data collection policy including: a vehicle data identifier, a trigger configured to define a trigger condition, and a plurality of trigger conditions having a plurality of trigger types, the plurality of trigger types including at least two of a signal trigger, a vehicle status trigger, a timing trigger, a schedule trigger, a geofence trigger, an error trigger, an environment trigger, or a user input trigger; and
a trigger evaluation circuit configured to:
determine a trigger event occurrence in response to a trigger condition and trigger evaluation data and based on a first portion of the plurality of trigger conditions, the first portion including a first trigger having a first trigger type and a second trigger having a second trigger type,
determine a trigger event termination based on a second portion of the plurality of trigger conditions, wherein the second portion includes a first trigger having a first trigger type and a second trigger having a second trigger type,
determine a data capture window in response to the trigger event occurrence, trigger event termination, and the data collection policy, and
capture identified vehicle data in response to the data capture window and the vehicle data identifier.
2. The vehicle of claim 1 , wherein the trigger evaluation circuit determines the trigger event occurrence by evaluating the trigger evaluation data using the trigger condition, wherein the trigger condition defines a relationship with a present value that may be satisfied or unsatisfied by the trigger evaluation data.
3. The vehicle of claim 1 , wherein the trigger evaluation data includes at least one of a vehicle state, a vehicle status, a vehicle operating mode, or a vehicle discrete event.
4. The vehicle of claim 1 , wherein the identified vehicle data is generated by the vehicle before the trigger event occurrence and stored using a rotating buffer circuit.
5. The vehicle of claim 1 , wherein the plurality of trigger conditions corresponds to one of a plurality of trigger evaluation data values.
6. The vehicle of claim 5 , wherein the trigger evaluation circuit determines the trigger event occurrence in response to at least two of the plurality of trigger conditions.
7. The vehicle of claim 5 , wherein:
the plurality of trigger conditions includes a trigger condition that corresponds to one of the plurality of trigger evaluation data values; and
the trigger evaluation circuit determines the trigger event occurrence in response to the trigger condition.
8. The vehicle of claim 5 , wherein the plurality of trigger evaluation data values correspond to a plurality of data types, including at least two of a controller area network (CAN) message, a CAN signal, an ethernet packet, a vehicle location, a vehicle status, and a diagnostic trouble code.
9. The vehicle of claim 5 , wherein the plurality of trigger evaluation data values correspond to a plurality of data types, including at least one of a controller area network (CAN) message, a CAN signal, an ethernet packet, a vehicle location, a vehicle status, and a diagnostic trouble code.
10. The vehicle of claim 1 , wherein the trigger evaluation data includes a virtual sensor value derived from a plurality of vehicle data values.
11. The vehicle of claim 1 , wherein the data capture window terminates after a delay following the trigger event termination in response to the data collection policy.
12. The vehicle of claim 1 , wherein the data capture window terminates based at least in part on one or more trigger conditions.
