Classification: CPC F | IPC F

Claim 14:
15. A non-transitory computer-readable medium comprising executable instructions that, when executed by a processor, cause the processor to provide an aftertreatment system preheating service configurable to:
obtain a first measurement indicative of a current temperature associated with an aftertreatment system downstream an engine of a vehicle;
obtain a second measurement indicative of a current state of an energy source coupled to a heating element integrated with the aftertreatment system within a housing of an emissions control device of the aftertreatment system and disposed upstream of a catalyst component within the housing of the emissions control device;
determine an amount of electrical energy to be applied to the heating element based at least in part on a difference between the current temperature associated with the aftertreatment system and a target temperature for the aftertreatment system;
automatically enable current flow from the energy source to the heating element for a duration of time prior to ignition of the engine in a manner that is influenced by the amount of electrical energy to be applied to the heating element and the current state of the energy source; and
automatically enable an auxiliary air injection device to provide fluid flow past the heating element through the aftertreatment system after enabling the current flow from the energy source to the heating element when a temperature associated with the heating element is greater than a threshold.
