Disclosed is a method of detecting the approach and/or contact of a user's hand to a door handle, the handle having a first outer surface oriented toward the vehicle and a second outer surface oriented toward the user, the handle including at least one detection electrode and an additional electrode, positioned face to face in advance. The method includes: the two electrodes are electrically connected to the same power supply source; a first capacitance value is measured at the terminals of the detection electrode; a second capacitance value is measured at the terminals of the additional electrode; and the first and second values are compared, during a measurement period, with one another and/or with a predetermined threshold value, in order to detect the approach of a user's hand toward the first outer surface or toward the second outer surface and/or the contact of his hand with one of these surfaces.
