Systems and methods for adjusting engine operating points based on emissions sensor feedback

A system for a hybrid vehicle, the system comprising:

• a controller coupled to an electrified powertrain and to at least one sensor disposed in an exhaust aftertreatment system of the hybrid vehicle, the controller structured to:
• receive emissions data from at least one sensor regarding exhaust gas from an engine;
• determine that an emissions level is at or above a predefined threshold based on the received emissions data;
• adjust an operating point of an engine of the electrified powertrain in response to the emissions level being at or above the predefined threshold and based on a fault code regarding the exhaust aftertreatment system;
• and
• control an electric motor of the electrified powertrain in response to the adjustment of the engine to compensate for a change in power output from the engine to reduce the emissions level to below the predefined threshold.

A method, comprising:

• receiving, by a controller, emissions data regarding an emissions level of a hybrid vehicle having an exhaust aftertreatment system from a sensor;
• determining, by the controller, that the emissions level is at or above a predefined threshold;
• adjusting, by the controller, an operating point of an engine of the hybrid vehicle based on the emissions level being at or above the predefined threshold and based on a fault code regarding the exhaust aftertreatment system;
• and
• controlling, by the controller, an elector motor in response to the adjustment of the operating point of the engine to compensate for a change in power output from the engine and to reduce the emissions level to below the predefined threshold.
