摘要：A method for regenerating a particulate filter in an exhaust system of acombustion engine. The method: (a) measures, every time the combustion engine is
started, a parameter representative of a condition of the combustion engine and/or ofthe exhaust system, (b) when the measured parameter reveals that the engine and/or theexhaust system are cold, the parameter representative of the mass of accumulated sootmeasured before the engine was last turned off is frozen, (c) the deviation between thefrozen mass parameter and the parameter representative of the mass measured at timet is continuously determined, and (d) when the deviation has been resolved by
convergence, it is added to the frozen mass parameter and the resulting corrected valueis used in an ongoing regeneration process.
