Abstract
An adaptive method for activating a vehicle function using a user's portable device and communicating in ultra-wideband with the vehicle. The function being activated based on the portable device's location by applying a predictive model trained beforehand using pairs of predetermined received signal strength values and predetermined time-of-flight values from a plurality of reference portable devices, and using authentication of the portable device, the method: establishing beforehand a bijective function linking the received signal strength values and the time-of-flight values; then: for a plurality of direct signals received from a new portable device: establishing a new bijective function; using each new pair of values for time-of-flight and received signal strength; calculating a received signal strength difference between the two bijective functions; applying the difference to the training received signal strength values; determining the location of the new portable device using the new pairs of received signal strength and time-of-flight values and by applying the modified predictive model; activating the vehicle function according to the location.
