TRIGGER METHOD TO START AN ACTIVE REGENERATION CYCLE OF A PARTICLE FILTER IN A VEHICLE

The invention relates to a trigger method to start an active regeneration cycle of a particle filter (12) in a vehicle (10), whereas a general drive index (GI) of the vehicle (10) is recorded, a current physical condition of the particle filter (12) is sensed, a current drive pattern (DP) of the vehicle (10) is sensed and a regeneration necessity is affirmed or negated based on a map (38) relating the general drive index (GI), the physical condition and the current drive pattern (DP) of the vehicle (10) to the regeneration necessity.
