Abstract (en)
[origin: WO2022229138A1] Method for calibrating an electronic expansion valve (5, 7, 8) within a thermal management device (1) for a motor vehicle, the opening of said electronic expansion valve (5, 7, 8) being able to be brought about by means of a stepping electric motor, the electronic expansion valve (5, 7, 8) comprising a first end stop (X1), referred to as the bottom stop in the direction of maximum closure of the electronic expansion valve (5, 7, 8) and a second end stop (X2), referred to as the top stop in the direction of maximum opening of the electronic expansion valve (5, 7, 8), each end stop being a reference position enabling calibration of the electronic expansion valve, said method comprising the following steps: - determining a predicted position (Z) of opening of the electronic expansion valve (5, 7, 8), - determining the number of steps between the predicted position (Z) of opening of the electronic expansion valve (5, 7, 8) and the first (X1) and second (X2) end stops, - selecting, as reference position, the end stop (X1, X2) that is the lowest number of steps away from the predicted position (Z) of opening, - calibrating the electronic expansion valve (5, 7, 8) by opening or closing said electronic expansion valve (5, 7, 8) as far as its selected reference position.
