    Abstract: A method, an optimization controller, and combustion engine are disclosed. The method includes determining, by an optimization controller, values of a performance parameter of a target vehicle using characteristics of at least two platoons travelling on a roadway, each of the values corresponding to a platoon of the at least two platoons; selecting, by the optimization controller, one of the at least two platoons based on a comparison of the values of the performance parameter, and coordinating, by the optimization controller, for the target vehicle to join the selected of the at least two platoons.

    Abstract: One embodiment is a system comprising an engine structured to output torque to an accessory drive, a rotary load structured to be selectably driven by the accessory drive, and an electronic control system. The electronic control system is operable to selectably engage and disengage the rotary load effective to vary the load on the engine, monitor engine load values in coordination with engagement of the rotary load, store a data set comprising the monitored engine load values in association with values of one or more associated system conditions in a non-transitory memory medium, update a mathematical model of the system stored in the non-transitory memory medium in response to the engine load values to converge one or more model parameters, diagnose or prognosticate a failure state of the rotary load in response to a change in the one or more model parameters, and output a perceptible diagnostic indication of the failure state in response to the diagnosis or prognostication.

    Abstract: Mild hybrid powertrain controls and apparatuses, methods and systems including the same are disclosed. One exemplary embodiment is a mild-hybrid system comprising an engine, an electrical machine, power electronics, an energy storage system, and an electrical load. The system includes a controller structured to receive an electrical machine power command based upon a power allocation to the electrical machine, process the electrical machine power command with feedforward controls structured to compensate for an inaccuracy associated with the power electronics, process the electrical machine power command with proportional integral (PI) controls structured to compensate for a power loss associated with one or more electrical loads, provide a compensated machine power command based upon the processing with the feedforward controls and the processing with the PI controls, and output the compensated machine power command to control the electrical machine.
