Abstract
A reducing agent dosing valve () on an exhaust system () of an internal combustion engine (), having a pump () which generates an injection pressure (p_), and having a control unit () which actuates the reducing agent dosing valve () with actuation signals is presented, wherein the actuation signals are formed in a manner dependent on a reducing agent pressure (p_) prevailing at the pump side. The method is distinguished by the fact that the actuation signals are formed additionally in a manner dependent on at least one estimated value for an influence of a drop in the injection pressure (p_), which occurs upon the opening of the reducing agent dosing valve (), on the injected reducing agent quantity.
