Method for controlling the power transmission and / or the torque transmission of a hydrodynamic machine and a control device therefor

摘要

Method for controlling the power transmission and / or torque transmission of a hydrodynamic machine (1), comprising a working space (6) formed by a bladed primary wheel (2) and a bladed secondary wheel (3), which can be filled with a working medium and an external working medium circuit (7), which is connected via an inlet channel (5) and an outlet channel (4) in the hydrodynamic machine (1) on the working space (6), wherein1.1 a degree of filling of the working space (6) with the working medium for adjusting the with Working fluid in the working space (6) from the primary wheel (2) to the secondary (3) transmitted power and / or with the working fluid from the primary wheel (2) to the secondary (3) transmitted torque is varied, and1.2 the degree of filling at least temporarily in Dependence of a temperature measurement of a temperature of the working medium directly or indirectly detected temperature sensor (18) is made; wherein1.3 the temperature sensor (18) provides the temperature reading of the working fluid at a sensor position; characterized in that1.4 a reference temperature of the working medium in the external working medium circuit (7) is detected or calculated and a position of the temperature sensor (18) determined from a comparison of the temperature measurement and the reference temperature and taken into account in the adjustment of the degree of filling of the working space (6) ,
