Systems and methods for reducing emissions with smart alternator

A system comprising:

• a controller of a vehicle that is coupled to an engine and an electric machine, the controller comprising at least one processor coupled to a memory storing instructions therein that, when executed by the at least one processor, cause the at least one processor to perform operations comprising:
• receiving information indicative of a temperature of an aftertreatment system of the vehicle and an exhaust gas characteristic;
• comparing the temperature of the aftertreatment system to a temperature threshold;
• comparing the exhaust gas characteristic to a characteristic threshold;
• and
• responsive to the comparisons indicating that the temperature of the aftertreatment system is below the temperature threshold and the exhaust gas characteristic is above the characteristic threshold, reducing a power consumption of an aftertreatment system heater to reduce a load on the engine such that a value of the exhaust gas characteristic decreases.

A non-transitory computer readable medium storing instructions thereon that, when executed by one or more processors of a processing circuit, cause the processing circuit to perform operations comprising:

• receiving information indicative of a temperature of an aftertreatment system and an exhaust gas characteristic;
• comparing the temperature of the aftertreatment system to a temperature threshold;
• comparing the exhaust gas characteristic to a characteristic threshold;
• responsive to the comparisons indicating that the temperature of the aftertreatment system is below the temperature threshold and the exhaust gas characteristic is below the characteristic threshold, engaging an aftertreatment system heater;
• responsive to the comparisons indicating that the temperature of the aftertreatment system is below the temperature threshold and the exhaust gas characteristic is above the characteristic threshold, reducing a power consumption of the aftertreatment system heater;
• and
• responsive to the comparisons indicating that the temperature of the aftertreatment system is above the temperature threshold and the exhaust gas characteristic is above the characteristic threshold, disengaging the aftertreatment system heater.
