Method for calibrating an electronic expansion valve within a thermal management device for a motor vehicle

A method for calibrating an electronic expansion valve within a thermal management device of a motor vehicle, the opening of said electronic expansion valve being drivable by an electric stepper motor, said electronic expansion valve including a first stop referred to as lower in the direction of maximum closure of the electronic expansion valve and a second stop referred to as upper in the direction of maximum opening of the electronic expansion valve, each stop being a reference position for calibrating the electronic expansion valve,

• said method comprising:
• determining a projected open position of the electronic expansion valve,
• determining the number of steps between the projected open position of the electronic expansion valve and the first and second stops,
• selecting, as reference position, the stop which is the fewest number of steps away from the projected open position,
• calibrating the electronic expansion valve by opening or closing said electronic expansion valve to its selected reference position.
