Abstract
Die Erfindung betrifft ein Verfahren und einen Regler zum Betrieb eines in einem Abgaskanal einer Verbrennungskraftmaschine angeordneten Abgassensors.The invention relates to a method and a controller for operating an exhaust gas sensor arranged in an exhaust passage of an internal combustion engine.
Es ist vorgesehen, dass eine Regelung von Betriebsparametern des Abgassensors durch einen modellbasierten Regler und/oder eine abgasstromabhängige Vorsteuerung von Betriebsparametern des Abgassensors erfolgt. It is provided that a control of operating parameters of the exhaust gas sensor by a model-based controller and / or an exhaust gas flow-dependent pilot control of operating parameters of the exhaust gas sensor takes place.
