Title: Method and device for controlling the regeneration of a particulate filter

Abstract: A method of controlling the regeneration of a particulate filter adapted to filter particulate matter present in exhaust emissions of an engine of a vehicle. The particulate filter is coupled to a heating device adapted to be activated so as to cause the heating of the particulate filter. The method includes sensing at least one operating parameter of the particulate filter, receiving sensed data relating to the at least one sensed operating parameter and conditioning the activation of the heating device based on a comparison of the received data with at least one respective threshold. The method further includes adjusting a value of the at least one threshold based on an operating condition of the vehicle, the operating condition being detected based on the received sensed data.
