Abstract

A vehicle electronic control unit (ECU) may control a vehicle subsystem and be configured to receive from a remote server via a vehicle telematics unit (TCU), a parameter definition of a processed parameter to be computed by the ECU; generate the processed parameter according to the parameter definition based on a raw parameter generated by the ECU; and send the processed parameter to a vehicle data buffer associated with the ECU for upload to the remote server via the TCU.

First claim

What is claimed is:

1. A vehicle system comprising:
a vehicle electronic control unit (ECU) controlling a vehicle subsystem and configured to
receive from a remote server via a vehicle telematics unit (TCU), a parameter definition specifying processing to be used by the ECU to generate a processed parameter from a raw parameter generated by the ECU, wherein the processed parameter is a down-sampled version of the raw parameter;
generate the processed parameter according to the parameter definition based on the raw parameter; and
send the processed parameter to a vehicle data buffer associated with the ECU for upload to the remote server via the TCU.

2. The system of claim 1 , wherein the down-sampling is performed according to decimation.

3. The system of claim 1 , wherein the ECU is connected to communicate messages with a plurality of other ECUs over a first vehicle network, and the vehicle data buffer associated with the ECU is configured to send the processed parameters to the TCU over a second vehicle network.

4. The system of claim 1 , wherein the parameter definition includes a unique identifier of the processed parameter.

5. The system of claim 1 , wherein the parameter definition includes a reporting application configured to be executed by a processor of the ECU to generate the processed parameter from the raw parameter.

6. A vehicle system comprising:
a plurality of electronic control units (ECUs), each configured to generate processed parameters from raw parameters according to processing specified by received parameter definitions;
a telematics control unit (TCU) configured to provide a data stream of the processed parameters to a remote server; and
a plurality of vehicle data buffers, each configured to receive the processed parameters from the plurality of ECUs and send the processed parameters to the TCU over a dedicated data-reporting vehicle network,
wherein the plurality of ECUs are configured to generate the processed parameters based on raw parameters generated by the plurality of ECUs, and at least one of the processed parameters is a down-sampled version of one of the raw parameters.

7. The system of claim 6 , wherein the down-sampling is performed according to decimation.

8. The system of claim 6 , wherein the parameter definition includes a reporting application configured to be executed by a processor of one or more of the plurality of ECUs to generate the processed parameter from the raw parameter.

9. The system of claim 6 , wherein the parameter definition includes a unique identifier of the processed parameter.

10. A computer-implemented method comprising:
generating a processed parameter as a down-sampled version of a raw parameter according to a parameter definition received from a remote server via a vehicle telematics unit (TCU) and specifying processing performed to a the raw parameter generated by an electronic control unit (ECU) to generate the processed parameter; and
sending the processed parameter to a vehicle data buffer associated with the ECU for upload to the remote server via the TCU.

11. The method of claim 10 , further comprising performing the down-sampling according to decimation.

12. The method of claim 10 , further comprising:
communicating messages between the ECU and a plurality of other ECUs over a first vehicle network, and
sending the processed parameters from the vehicle data buffer associated with the ECU to the TCU over a second vehicle network.

13. The method of claim 10 , wherein the parameter definition includes a unique identifier of the processed parameter.

14. The method of claim 10 , wherein the parameter definition includes a reporting application configured to be executed by a processor of the ECU to generate the processed parameter from the raw parameter.

15. The system of claim 1 , wherein the parameter definition includes software code configured to be executed by a processor of the ECU to generate the processed parameter from the raw parameter.

16. The system of claim 6 , wherein the parameter definitions include software code configured to be executed by a processor of one or more of the plurality of ECUs to generate the processed parameter from the raw parameter.

17. The method of claim 10 , further comprising updating a memory of the ECU according to the parameter definition that is received by the ECU, the parameter definition including software code configured to be executed by a processor of the ECU to generate the processed parameter from the raw parameter.
