Abstract

Verfahren zum Ermitteln der Temperatur eines Fluides in einer Hydraulikanordnung (24) für ein Kraftfahrzeug (10), wobei die Hydraulikanordnung (24) eine mittels eines Antriebsmotors (28) angetriebene Pumpenanordnung (26) und einen mit einem Druckanschluss (34) der Pumpenanordnung (26) verbundenen Drucksensor (42) zur Messung des Druckes (P) des Fluides aufweist, und wobei die Pumpenanordnung (26) über eine Leckagestelle (44) mit einem Tank (30) verbunden ist. Dabei wird die Temperatur (T) des Fluides auf der Grundlage eines für die Hydraulikanordnung (24) spezifischen Zusammenhanges (56, 58) zwischen einer Zustandsvariablen (n) des Antriebsmotors (28) und der Temperatur (T) des Fluides bei einem vorgegebenen Druck (P) des Fluides ermittelt.

Method for determining the temperature of a fluid in a hydraulic arrangement (24) for a motor vehicle (10), wherein the hydraulic arrangement (24) comprises a pump arrangement (26) driven by a drive motor (28) and a pump connection (34) connected to the pump arrangement (26 ) connected pressure sensor (42) for measuring the pressure (P) of the fluid, and wherein the pump assembly (26) via a leakage point (44) is connected to a tank (30). In this case, the temperature (T) of the fluid is determined at a predetermined pressure on the basis of a relationship (56, 58) specific to the hydraulic arrangement (24) between a state variable (s) of the drive motor (28) and the temperature (T) of the fluid. P) of the fluid determined.
