Abstract
A method includes determining an amount of particulate mass in a particulate filter of an exhaust aftertreatment system. The method includes, when the amount of particulate mass in the particulate filter is greater than a threshold particulate mass value, receiving engine state information, providing electric power to the particulate filter, and obtaining an impedance value of the particulate filter in response to providing the electric power. The method includes, when the amount of particulate mass in the particulate filter is greater than a threshold particulate mass value, determining a temperature of the particulate filter based on the impedance value, and adjusting a magnitude of the electric power in response to at least one of (i) the temperature of the particulate filter satisfying one or more temperature metrics and (ii) the engine state information satisfying one or more engine state metrics.
