1. A vehicle system comprising:
- a vehicle electronic control unit (ECU) controlling a vehicle subsystem and configured toreceive 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.

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.

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. - View Dependent Claims (7, 8, 9, 16)
