Abstract
A method for detecting the presence of a human hand on an opening element of a motor vehicle. The method includes determination of a power variation profile and detection of the presence of a human hand on the opening element being performed when the determined profile corresponds to a predetermined reference profile characterized by an increase followed by a first decrease in the power value, characterizing the approach of a human hand, followed by a stagnation and a second decrease in the power value, characterizing contact of a human hand with the opening element of the vehicle.
