    Abstract: A method for controlling a turbocharger is provided. The turbocharger has a turbine operatively connected to an exhaust of an internal combustion engine, and a compressor operatively connected to an intake of the engine. The method includes determining a boost pressure command for the compressor. The boost pressure command is configured to provide sufficient combustion reactant for the engine. The method includes calculating a compressor power from the determined boost pressure command, and calculating a turbine flow from the calculated compressor power. The method commands the turbocharger to operate at the calculated turbine flow.

    Abstract: A system in a vehicle includes memory to store driving history and charging history of the vehicle. The system also includes a processor to obtain a predicted battery life of one or more battery packs of the vehicle based on the driving history and the charging history, obtain a targeted battery life of a user indicating a mileage goal for a specific charge capacity of the one or more battery packs, and determine a difference between the predicted battery life and the targeted battery life. The processor solves an optimization problem to determine a future charging strategy to achieve the targeted battery life and controls an onboard charging system or an external charger based on the future charging strategy or controls routing or navigation based on the future charging strategy.

    Abstract: A system for control of a battery system includes a processor electrically connected to the battery system. The processor is configured to perform, in real time during a charging process, acquiring a set of charging parameter measurements, and estimating a dynamic performance variable in real time, the dynamic performance variable related to an electrochemical phenomenon occurring within the battery system during the charging process. The processor is also configured to perform, in real time during the charging process, determining a charging limit based on the dynamic performance variable and a model of the battery system, predicting a future state of the battery system, generating a target current profile based on the future state and the charging limit, the target current profile configured to maintain the dynamic performance variable within the charging limit, and controlling the current applied to the battery system based on the target current profile.

    Abstract: Embodiments include battery health detection based on natural soaking response. Aspects include measuring a plurality of characteristics of a battery pack at a first time and measuring the plurality of characteristics of the battery pack at a second time that is after the first time. Aspects also include inputting the plurality of characteristics and a difference between the first time and the second time into a trained model for identifying anomalies and determining, based on the trained model, whether the battery pack includes an anomaly. Based on a determination that the battery pack includes the anomaly, aspects include flagging the battery pack as containing the anomaly.

    Abstract: A method for controlling continuous and discrete actuators (e.g., modes) in a powertrain system includes receiving preview information from a sensor(s) describing an upcoming dynamic state at a future time point, and providing control inputs for the actuators to a controller that includes the preview information. The input set collectively describes a future torque or speed output state at the future time point. The controller processes the input set via a dynamical predictive model, in real time, to determine control solutions to take at the present time point for implementing the dynamic state at the future time point. A lowest opportunity cost control solution is determined and optimized. The controller executes the optimized solution at the present time step.

    Abstract: An engine includes an exhaust gas recirculation system with a high pressure exhaust gas recirculation loop and a low pressure exhaust gas recirculation loop, and an air charging system. A method of controlling the air charging system includes monitoring an actual exhaust gas recirculation rate, operating conditions of a compressor and turbine in the air charging system. A compressor flow is determined based on a target exhaust gas recirculation rate, a target intake manifold pressure and the actual exhaust gas recirculation rate. A power requested by the compressor is determined based on the compressor flow, the target intake manifold pressure, and the monitored operating conditions of the compressor. A power to be generated by the turbine is determined based upon the power requested by the compressor. A turbine flow is determined based upon the power to be generated by the turbine and the monitored operating conditions of the turbine. A system control command is determined based on the turbine flow and the monitored operating conditions of the turbine. The air charging system is controlled based on the system control command.
