Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLC
Field: Environmental technology (Chemistry)
Classification: CPC F | IPC F

Claim 9:
10. A vehicle system comprising:
an energy source;
an emissions control device including a heating element coupled to the energy source and at least one catalyst component, the heating element being disposed upstream of the at least one catalyst component within a housing of the emissions control device;
a temperature sensing element to obtain a first measurement indicative of a current temperature associated with the emissions control device;
an auxiliary air injection device upstream of the emissions control device to provide a fluid flow past the heating element through the emissions control device; and
a control module coupled to the heating element and the energy source, wherein the control module is configurable to:
detect a potential startup condition for an engine upstream of the emissions control device;
obtain a second measurement indicative of a current state of the energy source;
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 and a target temperature for the at least one catalyst component;
automatically enable current flow from the energy source to the heating element for a duration of time 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 the auxiliary air injection device to provide the fluid flow past the heating element 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.
