Abstract

See full text

A method for correcting for aging in particulate matter sensors for a diesel engine includes calculating calculated particulate matter values for a modeled diesel engine exhaust system over a period of time, measuring measured test particulate matter values with a test particulate matter sensor over the period of time in a test diesel engine exhaust system, determining differences between the calculated particulate matter values and the measured test particulate matter values from the test particulate matter sensor over the period of time, and correcting measured particulate matter values in at least one other particulate matter sensor over a same period of time based on the determined differences to obtain a corrected particulate matter value. A particulate matter sensor arrangement and a vehicle including a particulate matter sensor arrangement are also provided.
