Systems and methods for controlling cylinder deactivation operation in electrified powertrains

A system of 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 system comprising:

• one or more memories having instructions;
• and
• one or more processors configured to execute the instructions to perform operations comprising:
• 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
• in response to the predetermined operating condition not being met,
• adjusting the CDA operation by adjusting the duration of the CDA operation,
• wherein the duration of the CDA operation is adjusted based at least partially on an output of a cost function applied to performance data.
