ABSTRACT:
A method of controlling the energization of a heating device for the regeneration of a particle filter disposed in the exhaust duct of an internal combustion engine, particularly a Diesel engine, wherein a measure for the soot charge state of the particle filter the exhaust gas back pressure is determined while the engine is preferably idling, the exhaust gas recirculation is switched off, and predetermined conditions are present in the exhaust gas duct upstream of the particle filter, and then an exhaust gas back pressure signal is compared with a threshold value indicating a soot charge sufficient for the initiation of a regeneration of the particle filter and the heating device is enabled for the initiation of the regeneration procedure if the exhaust gas back pressure signal is greater than the threshold value.
