    Abstract: At least some embodiments of the present disclosure are directed to systems and methods for controlling a cylinder deactivation (CDA) operation for an electrified powertrain, the electrified powertrain comprising an engine and an additional power source, the engine having a plurality of cylinders. The method includes the step of: operating the electrified powertrain in a CDA mode and deactivating one or more selected cylinders of the plurality of cylinders; receiving measurement data indicative of operating conditions of the electrified powertrain; analyzing the measurement data to determine whether a predetermined operating condition is met; and adjusting the CDA operation by adjusting the duration of the CDA operation or changing a number of deactivated cylinders.

    Abstract: A system and method used to predict the state of health of a battery in a powertrain of a vehicle including a vehicle route profile generator arranged to generate a vehicle specific rout profile based on historical vehicle driving information, are disclosed. In one example, the system and method also include a powertrain model to convert the vehicle specific route profile to a predicted battery demand profile, and a state of health profile generator to generate a predicted state of health profile of the battery based on the predicted battery demand. In another example, the system further includes a vehicle performance manager arranged to generate a command to modify operation of the powertrain to extend battery life based on the vehicle specific route profile.
