用于运行机动车的流体回路的方法以及相应的流体回路
Abstract:
本发明涉及一种用于运行机动车的流体回路(1)的方法，所述流体回路(1)具有主回路(2)、通过机械的调温阀(9)连接到所述主回路(2)上的副回路(3)以及用于输送流体的电动的流体输送装置(4)。在此提出，在检查运行模式中在检查时间段期间将所述流体输送装置(4)调整到确定的检查转速并且求得所述流体输送装置(4)所需的电流的实际电流强度，其中，在所述流体的实际温度小于所述调温阀(9)的转换温度时，将所述实际电流强度作为第一电流强度值储存，并且在实际温度大于所述转换温度时，将所述实际电流强度作为第二电流强度值储存，其中，当所述第二电流强度值大于所述第一电流强度值时，识别出所述调温阀(9)的功能正常。此外，本发明涉及一种用于机动车的流体回路(1)。
Abstract(English):

The invention relates to a method for operating a fluid circuit (1) of a motor vehicle, which fluid circuit has a main circuit (2), a secondary circuit (3) connected to the main circuit (2) by means of a mechanical thermostatic valve (9), and an electric fluid-conveying device (4) for conveying a fluid. According to the invention the fluid-conveying device (4) is set to a certain test rotational speed in a test operating mode and the actual amperage of the current required by the fluid-conveying device (4) is determined during a testing time period, wherein the actual amperage is stored as a first amperage value in the case of an actual temperature of the fluid that is less than a switching temperature of the thermostatic valve (9) and is stored as a second amperage value in the case of an actual temperature that is greater than the switching temperature, wherein proper function of the thermostatic valve (9) is granted if the second amperage value is greater than the first amperage value. The invention further relates to a fluid circuit (1) for a motor vehicle.
