Control instrument for cleaning out accumulations in a motor vehicle catalytic converter monitors the cleaning cycle by checking environmental constraints to avoid adding to environmental burdens in areas with smog or ozone

A control instrument (1) connects to a navigational instrument (3) storing data for a current travelling route. Before starting a cleaning procedure the control instrument uses a known travelling route to check at what time point and at what spot accumulations (8) in a catalytic converter can be cle...

Beschreibung
Zusammenfassung:	A control instrument (1) connects to a navigational instrument (3) storing data for a current travelling route. Before starting a cleaning procedure the control instrument uses a known travelling route to check at what time point and at what spot accumulations (8) in a catalytic converter can be cleaned out. Environmental constraints are checked to avoid adding to environmental burdens in a city or areas with traffic restrictions because of smog or ozone levels. Disclosed is a control device for a storage catalytic converter in a motor vehicle which is used to control and monitor the cyclic cleaning process. The control device (1) is connected to a navigation system (3) in which route-related information is stored. Before the cleaning process starts, the control device (1) verifies, on the basis of known route information, at what time and place a cleaning of the storage catalytic converter (8) can be carried out. The verification is based on environmental restrictions which seek to avoid pollution, for example within a city or a spa area or in zones with driving limitations (e.g. because of a smog or ozone alarm). The cleaning process is effected manually or automatically. Erfindungsgemäß wird ein Steuergerät für einen Speicherkat eines Kraftfahrzeugs zur Steuerung und Überwachung des zyklischen Reinigungsvorgangs vorgeschlagen. Das Steuergerät (1) ist dabei mit einem Navigationsgerät (3) verbunden, in dem die Daten für die aktuelle Fahrtroute gespeichert sind. Vor der Reinigungsprozedur prüft das Steuergerät (1) anhand der bekannten Fahrtroute, zu welchem Zeitpunkt und welchem Ort eine Reinigung des Speicherkats (8) durchgeführt werden kann. Die Prüfung erfolgt anhand von Umweltbeschränkungen, um Belastungen beispielsweise innerhalb eines Stadt-, Kurgebiets oder in Zonen mit Verkehrsbeschränkungen (z. B. wegen Smog- oder Ozonalarm) zu vermeiden. Die Auslösung der Reinigungsprozedur erfolgt manuell oder automatisch.
