1. A method for locating a user device in a sub-zone of a main zone defined with respect to a vehicle, said vehicle comprising a plurality of transceivers and an electronic control unit that is configured to determine the position of the user device based on signals sent by the user device and received by the transceivers, said method comprising steps, implemented by the vehicle, of:
periodically determining the position of the user device based on signals sent by the user device and received by the transceivers;
detecting the user device in a first sub-zone;
locating the user device in said first sub-zone;
keep locating the user device in the first sub-zone for as long as the user device is detected in said first sub-zone;
detecting the user device in a second sub-zone;
when the user device is simultaneously detected in both the first sub-zone and the second sub-zone or when the user device is detected between the first sub-zone and the second sub-zone, keep locating the user equipment in the first sub-zone; and
