The method involves driving a pump assembly (26) by a drive motor (28) in a hydraulic system (24). A pressure connection (34) of the pump assembly is connected to a pressure sensor (42) for measuring the pressure of the fluid. The pump assembly is connected with a tank (30) through a leakage point (44). The temperature of the fluid is determined, based on the specific relationship between state variable of the drive motor of the hydraulic system and the temperature of the fluid at predetermined pressure of the fluid. An independent claim is included for a hydraulic system for motor vehicle. |
