description A method for operating a particulate filter (12) in the exhaust system of an internal combustion engine comprises a filtering phase in which particles from exhaust gas of the combustion engine are collected in the filter, and a filter cleaning phase (t1-t5) in which the filter (12) is held in a temperature range in which particles collected in the filter (12) are burnt. At least during a main portion (t2-t5) of the filter cleaning phase (t1-t5), the temperature (Ts) of the filter (12) is gradually raised. In an ignition portion (t1-t2) prior to said main portion (t2-t5) the temperature (Ts) of the filter (12) is higher than at the beginning (t2-t3) of the main portion (t2-t5).
