Remedial action for invalid particulate filter soot

A method for controlling soot loading estimation for a gas particulate filter in a motor vehicle, the method comprising:

• checking validity of soot loading estimation performed by a controller, the validity determined based on detection of a fault of a sensor;
• in response to the soot loading estimation being invalid, initiating a remedial action to limit soot deposition on the gas particulate filter, the remedial action comprising:
• determining a temperature at an inlet of the gas particulate filter;
• and
• if the temperature is within a predetermined range, inhibiting a deceleration fuel cut off of an internal combustion engine.

A computer program product comprising a memory storage device having computer executable instructions stored therein, the computer executable instructions when executed by a processor causes the processor to execute a computer-implemented method for a remedial action for invalid particulate filter soot in an exhaust system in a vehicle, the method comprising:

• checking validity of soot loading estimation for a gas particulate filter, the soot loading estimation performed by a controller, the validity determined based on detection of a fault of a sensor;
• and
• in response to the soot loading estimation being invalid, initiating a remedial action to limit soot deposition on the gas particulate filter, the remedial action comprising:
• determining a temperature at an inlet of the gas particulate filter;
• and
• if the temperature is within a predetermined range, inhibiting a deceleration fuel cut off of an internal combustion engine.
