Abstract
An activation module, intended to be fitted to a motor vehicle for the purpose of activating a function of the vehicle from a portable access device carried by a user, the module including: a single coil; a first controller for a device for detecting pressure from the hand of the user; a second controller for a near-field communication device; a selector, connected to the single coil, having two positions: a first position in which the selector connects the single coil to the first controller in order to constitute the pressure detection device; a second position in which the selector connects the single coil to the second controller in order to constitute the near-field communication device; a target having a void, the target being located facing the single coil; an impedance-adjuster that is connected to the target; and a controller for the selector.
