Method for managing location of a user device in a passenger compartment of a vehicle

A method for managing location of a user device in a passenger compartment of a vehicle, said vehicle comprising a plurality of transceivers, a position of the user device having previously been determined in the passenger compartment of the vehicle from distances between each transceiver and the user device, the method comprising the following steps implemented by the vehicle:

• receiving, by way of each transceiver, a request signal transmitted by the user device, said request signal comprising an identifier of the user device,
• transmitting to the user device, by way of each transceiver, a response signal comprising an identifier of said transceiver,
• receiving, by way of each transceiver, a location signal transmitted by the user device and comprising the identifier of the user device and the identifier of said transceiver,
• calculating the distance of the user device in relation to each of the transceivers from the received response signals,
• calculating, for each transceiver, the difference between the distance between said transceiver and the user device that has been calculated and the distance between said transceiver and the user device that was previously used to determine the position of the user device in the passenger compartment,
• when one of the differences calculated in relation to one of the transceivers is erroneous by being higher than a predetermined inconsistency threshold, calculating the position of the user device from the received response signals by excluding the response signal received for said transceiver,
• calculating the positional variation of the user device between the calculated position and the previously determined position,
• when the calculated positional variation is higher than a predetermined movement detection threshold, calculating the position of the user device from the received response signals by including all of the received response signals.
