Abstract
A method for an exhaust-gas treatment system having a diesel particle filter, in particular for the operation of an internal combustion engine having an exhaust-gas treatment system, in particular an internal combustion engine including a motor. The method includes the steps of: operating the diesel particle filter, in particular with regular regeneration; and determining a present soot loading of the diesel particle filter. Provision is made for a comparison of the present soot loading with a predetermined soot loading reference value to be performed and, if the soot loading reference value is undershot, for the soot particle loading in the diesel particle filter to be increased in order to adhere to the demanded emission limit value for the number of soot particles.
