Systems and methods for cold operation NOx burden reduction

A system comprising:

• a controller coupled to an aftertreatment system, the controller configured to:
• initiate a low engine-out NOx (LEON) mode by controlling a component of a vehicle having the aftertreatment system to decrease an instantaneous engine-out NOx (EONOx) amount;
• compare a temperature of the aftertreatment system to a warm-operation threshold temperature;
• responsive to determining that the temperature of the aftertreatment system exceeds the warm-operation threshold temperature, disengage the LEON mode;
• responsive to determining that the temperature of the aftertreatment system is below the warm-up operation threshold temperature, compare information indicative of an operating status of the vehicle to a LEON exit threshold, wherein the information indicative of the operation status of the vehicle comprises a NOx value and the LEON exit threshold comprises a NOx value threshold;
• and
• disengage the LEON mode responsive to determining that the NOx value exceeds the NOx value threshold.

A non-transitory computer readable medium having computer-executable instructions embodied therein that, when executed by at least one processor of a computing system, cause the computing system to perform operations comprising:

• initiating a low engine-out NOx (LEON) mode by controlling a component of a vehicle having an aftertreatment system to decrease an engine-out NOx (EONOx) amount;
• comparing a temperature of the aftertreatment system to a warm-operation threshold temperature;
• responsive to determining that the temperature of the aftertreatment system exceeds the warm-operation threshold temperature, disengaging the LEON mode;
• responsive to determining that the temperature of the aftertreatment system is below the warm-up operation threshold temperature, comparing information indicative of an operating status of the vehicle to a LEON exit threshold, wherein the information indicative of the operation status of the vehicle comprises a NOx value and the LEON exit threshold comprises a NOx value threshold;
• and
• disengaging the LEON mode responsive to determining that the information indicative of the operating status of the vehicle exceeds the LEON exit threshold.
