ABSTRACT:
A method for regeneration of a particulate filter in which the attainment of a stable idling operating condition of the diesel engine is waited for, at least within a specifiable time period after the starting of the diesel engine, rotation-speed signals of the diesel engine being registered in the specifiable time period, before a control device registers and evaluates further operating values and outputs control commands to devices of the particulate-filter system in order to insure reliable burning off of soot particles deposited in the particulate filter and prevent damage to the particulate filter due to incorrect control actions.
