The invention relates to a method for activating a function of a motor vehicle by means of an activation device comprising at least four ultra-wide-band communication external antenna modules and an ultra-high-frequency communication module, from an item of “hands-free” portable access equipment (SD) carried by a user, comprising an accelerometer, a gyroscope and a magnetometer, the activation of the function being triggered by detection of the presence of the user in a predetermined zone around the vehicle, and depending on an authentication result, the method comprising the following steps:s) determining an initial position of the item of access equipment with respect to the vehicle,t) measuring the values from the gyroscope, from the magnetometer and from the accelerometer,u) obtaining a value of the probability of the intention to activate a vehicle function,v) comparing the probability value with at least one predetermined threshold,w) transmitting, at ultra-high frequency from said item of equipment to said vehicle, a request to place the external antenna modules in partial or full ultra-wide-band communication operation, depending on the result of said comparison,x) activating the vehicle function, depending on an estimate of the distance between said item of equipment and the vehicle made by said external antenna modules thus activated in the ultra-wide band.
