Classification: CPC B  Y | IPC B

Claim 0:
1. A system, comprising:
a fuel-fed engine;
a primary drivetrain of a tractor unit coupled to the fuel-fed engine;
an engine control module (ECM) for the fuel-fed engine coupled to a controller area network (CAN) interface;
an electric drive axle configured to operate independently of the primary drivetrain; and
an equivalent consumption minimization strategy (ECMS) controller for the electric drive axle coupled to the network interface, wherein the ECMS controller is configured to:
retrieve from the ECM a signature indicative of the fuel-fed engine wherein the signature is indicative of both the fuel-fed engine and the primary drivetrain of the tractor unit;
communicate over a wireless communication interface to retrieve brake-specific fuel consumption (BSFC) type data from an information store at least partially hosted by a network-connected service platform at least upon recognition of a new signature after coupling to the controller area network interface in response to the retrieval of the signature indicative of the fuel-fed engine, wherein a locally hosted portion of the information store is updated with the retrieved BSFC type data via the network-connected service platform periodically, on-demand, or in response to a command received over a radio frequency data communication interface;
determine a through-the-road (TTR) equivalent consumption minimization strategy (ECMS) independent of any driver inputs; and
control motive torque supplied by the electric drive axle in accordance with the TTR ECMS.
