Efficient telematics data upload
A system includes at least one processor configured to, in response to receiving a VIN from a remote vehicle, transmit to the vehicle a parameter definition selected based on fields of the VIN to configure an ECU of the vehicle to enter a logging mode to capture, aggregate, and send operational data of the vehicle, and a bandwidth configuration file for a modem of the vehicle based on historical throughput requirements associated with operational data. The parameter definition may include a reporting application configured to be executed by a processor of the ECU to generate a processed parameter from a raw parameter associated with vehicle operation. Also, the parameter definition may include updated firmware for the ECU, and the reporting application is configured to be executed by the ECU after the updated firmware is installed in the ECU.
1. A system comprising:
a processor configured to, responsive to receiving a VIN from a remote vehicle and data about an internal bandwidth of a bus of the vehicle and a transfer rate of a connection between the vehicle and processor, transmit to the vehicle a parameter definition selected based on fields of the VIN, the internal bandwidth, and the transfer rate, wherein the parameter definition is configured to prompt
a telematics control unit of the vehicle to select an alternative channel to operate on to increase available bandwidth of the connection between the vehicle and processor, and
an ECU of the vehicle to enter a logging mode to capture operational data of the vehicle, to decimate the operational data to generate compressed operational data and conserve the internal bandwidth of the bus of the vehicle, and send the compressed operational data to the processor via the connection between the vehicle and processor.
2. 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 a processed parameter from a raw parameter associated with vehicle operation.
3. The system of claim 2 , wherein the parameter definition includes updated firmware for the ECU, and the reporting application is configured to be executed by the ECU after the updated firmware is installed in the ECU.
4. The system of claim 2 , wherein the parameter definition includes a unique identifier of the processed parameter.
5. The system of claim 1 , wherein the processor is configured to, in response to receiving the operational data from the vehicle, transmit to the vehicle an updated parameter definition selected based on the fields and operational data to reconfigure the ECU to exit the logging mode.
6. The system of claim 1 , wherein the processor is further configured to receive from the vehicle after a delay after transmission of the parameter definition, a data stream from the vehicle indicative of operation of the vehicle configured with the parameter definition, and transmit to the vehicle a new parameter file for a different ECU based on the data stream.
