The invention relates to a method (61) for controlling a regeneration process of an exhaust gas particle filter (41) of an internal combustion engine (11), wherein said method (61) comprises safeguards (71) for protecting said exhaust gas particle filter (41) from overheating and when implementing said safeguards (71) a gas flow (ma) of the gas flowing through the exhaust gas particle filter (41) is reduced (71a, 71b) for the purpose of restricting a reaction rate of an exothermal reaction taking place in said exhaust gas particle filter (41) during the regeneration process. In order to allow for an efficient regeneration of an exhaust gas particle filter (41) and still avoid damage to or the destruction of said exhaust gas particle filter (41) as a result of the overheating thereof, the invention is characterized in that during the regeneration process an instantaneous value (x(t)), which characterizes an instantaneous mass (x) of the soot situated in the exhaust gas particle filter (41), is ascertained, a check (67) is made as a function of the instantaneous value (x(t)) to determine whether said exhaust gas particle filter (41) is in an uncritical operating state and said safeguards (71) are suppressed in the event that the uncritical operating state is present. |
