Monitoring motor vehicle part temperature sensor operability, involves checking for defined minimum temperature change over defined period of measurement with starting temperature as reference value

The method involves checking for the presence of a defined minimum temperature change over a defined time period in which the sensor is measuring a motor vehicle part's temperature by using the temperature value at the start of the period as a reference value, whereby the star of the checking c...

Beschreibung
Zusammenfassung:	The method involves checking for the presence of a defined minimum temperature change over a defined time period in which the sensor is measuring a motor vehicle part's temperature by using the temperature value at the start of the period as a reference value, whereby the star of the checking coincides with time of starting the motor vehicle's engine. Die Erfindung betrifft ein Verfahren zur Überwachung der Funktionsfähigkeit eines Temperatursensors für die Erfassung einer Temperatur in einer Kraftfahrzeugkomponente, wobei die Temperatur mittels des Sensors gemessen wird und das Vorliegen einer vorbestimmten Mindesttemperaturänderung (DELTAT¶min¶) über einen vorbestimmten Zeitraum geprüft wird.
