Abstract
Motor vehicle equipped with a system for detecting the approach of a user, comprising a metallic surface (15) which is isolated from the chassis of the vehicle (V) and is connected to a high-frequency wave generator (16), so that the pair formed by the chassis of the vehicle and the said surface defines a radiating dipole, and a capacitance-variation detector (2) which is connected to the said surface and is intended to detect the variation in capacitance of a capacitor (C) formed by the (surface (15)/user's hand) pair.
