Claim 9:
10. An after-treatment system of a vehicle comprising:
an electrically heated catalyst, electrically coupled to a power source;
a particulate filer; and
a controller, communicatively coupled to the electrically heated catalyst, the particulate filter, and the power source, the controller configured to:
monitor a first operational parameter of the electrically heated catalyst;
monitor a second operational parameter, different to the first operational parameter, of the particulate filter;
determine if the first operational parameter is outside a first threshold range;
determine if the second operational parameter is approaching a second threshold range;
in response to the first operational parameter being outside the first threshold range and the second operational parameter being within the second threshold range, initiate a regeneration sequence of the after-treatment system configured to regenerate at least the electrically heated catalyst;
determine if the first operational parameter of the electrically heated catalyst is outside of a third threshold range, larger than the first threshold range; and
in response to the first operational parameter not being outside of the third threshold range, initiating a regeneration sequence configured to regenerate the electrically heated catalyst and the particulate filter.
