ABSTRACT:
The invention relates to a method to regulate and/or calibrate a mixing valve, in particular in a cooling circuit of an internal combustion engine, with which a volume flow can be separated into two partial flows as a function of controlled quantity, whereby the separating ratio of the mixing valve is determined by comparing a target quantity with an actual measured quantity. It is planned that a correction value that is computed during operation is taken into consideration in calculating the separating ratio or mixing ratio (MR). In addition, the invention relates to a corresponding regulating device to regulate and/or calibrate a mixing valve. In this case, it is planned that a correction value that is computed during operation can be taken into consideration in calculating the separating ratio.
