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

摘要

The invention relates to a method for controlling the power transmission and / or torque transmission of a hydrodynamic machine, in particular a hydrodynamic retarder, comprising a working space formed by a bladed primary wheel (2) and a bladed secondary, fillable with a working medium and an external working medium circuit , which is connected via an inlet channel and an outlet channel in the hydrodynamic machine to the working space, wherein - a degree of filling of the working space with the working fluid for adjusting the transferred with the working fluid in the working space from the primary to the secondary wheel power and / or with the working fluid from the primary wheel is varied to the secondary wheel torque transmitted, and - the degree of filling at least temporarily as a function of a temperature measurement of the temperature of the working medium directly or indirectly detected tempera tursensors is set; wherein - the temperature sensor provides the temperature reading of the working fluid at a sensor position. The invention is characterized in that a reference temperature of the working medium in the external working medium circuit is detected or calculated and a position of the temperature sensor is determined from a comparison of the temperature measured value and the reference temperature and taken into account in the adjustment of the degree of filling of the working space.
