Systems and methods for monitoring a temperature of a particulate filter of an exhaust aftertreatment system

A system comprising:

• a processor;
• and
• a nontransitory computer-readable medium comprising instructions that are executable by the processor, wherein the instructions comprise:
• determining an amount of particulate mass in a particulate filter of an exhaust aftertreatment system;
• and
• when the amount of particulate mass in the particulate filter is greater than a threshold particulate mass value:
• receiving engine state information, wherein the engine state information includes an engine speed value;
• providing electric power to the particulate filter;
• obtaining an impedance value of the particulate filter in response to providing the electric power;
• determining a temperature of the particulate filter based on the impedance value;
• and
• adjusting at least one of a pulse width and an amplitude of the electric power based on a comparison between (i) the engine speed value to a maximum threshold engine speed value and a minimum threshold engine speed value and (ii) the temperature to a maximum temperature threshold.
