A method and apparatus for carrying out the method for influencing the operating temperature of a hydraulic operating medium for a drive unit of a vehicle

摘要

In the case of a method for influencing the operating temperature of a hydraulic operating medium for a drive unit of a vehicle is in a selected region of the operating temperature of the operating medium the operating temperature by controlling the time volume flow of the operating medium for the exchange of heat between the operating medium and a secondary - fluid used as the heat transfer medium to a predetermined desired value in dependence on the actual value of the operating temperature and / or as a function of the actual value of at least one other vehicle parameters, by means of which a certain temperature influence of medium u.sub.0 on medium u.sub.7 end effect on the operating medium can be foreseen, can be adjusted automatically. The selected region of the operating temperature, which includes in the warm-up phase of the drive unit as well as the occurring relative to the desired value is a substantially higher temperature values.
