Abstract
Regeneration of a diesel particle filter of an internal combustion engine of a vehicle is controlled according to soot mass loading and the vehicle operating condition. Regeneration modes include active regeneration and forced passive regeneration, and operating conditions include highway, town and off-road driving. One strategy may determine initiation of regeneration, and another may determine cessation. Regeneration mode may change in real time.
