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.

Claims

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 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.

2. The system of claim 1, wherein the processed parameter is a down-sampled version of the raw parameter.

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

4. 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.

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

6. 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.

7. A vehicle system comprising:

a plurality of electronic control units (ECUs), each configured to generate processed parameters according to 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.

8. The system of claim 7, wherein the ECUs are configured to generate the processed parameters based on raw parameters generated by the ECU, and at least one of the processed parameters is a down-sampled version of one of the raw parameters.

9. The system of claim 8, wherein the down-sampling is performed according to decimation.

10. The system of claim 8, 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.

11. The system of claim 7, wherein the parameter definition includes a unique identifier of the processed parameter.

12. A computer-implemented method comprising:

receiving from a remote server via a vehicle telematics unit (TCU), a parameter definition of a processed parameter to be computed by the electronic control units (ECU);

generating the processed parameter according to the parameter definition based on a raw parameter generated by the ECU; and

sending the processed parameter to a vehicle data buffer associated with the ECU for upload to the remote server via the TCU.

13. The method of claim 12, wherein the processed parameter is a down-sampled version of the raw parameter.

14. The method of claim 13, further comprising performing the down-sampling according to decimation.

15. The method of claim 12, 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.

16. The method of claim 12, wherein the parameter definition includes a unique identifier of the processed parameter.

17. The method of claim 12, 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.
