Abstract
A method for activating a vehicle function using an activation device, having at least two transceivers communicating with a portable user appliance and communicating with each other via ultra-wideband communication. The method includes: transmitting using a first transceiver; computing a radius of a circle centered around the first transceiver as a function of the time of flight of the waves reflected by the portable appliance, and determining a perimeter of the circle; comparing a profile of received reflected waves originating from the second transmitter with a predetermined received wave profile; detecting a presence as a function of the result of the comparison; computing, if a presence is detected, a distance between the second transceiver and the presence; locating the portable appliance by computing an intersection between the distance and the perimeter; and activating the vehicle function as a function of the location.
