Abstract
The present disclosure relates to a controller apparatus for regenerating a particulate matter sensor. The controller apparatus includes a sensing module configured to detect a soot loading on a particulate matter sensor and generate a regeneration request indicating a desired regeneration temperature and a heating module configured to receive the regeneration request and send a heating command signal to a heating element based on the regeneration request. The controller apparatus further includes an electrical resistance module configured to detect an electrical resistance in the heating element and determine an actual temperature of the heating element and a temperature feedback module configured to modify the heating command signal according to the difference between the desired regeneration temperature and the actual temperature. The present disclosure also includes a related method and system.
