Use of vehicle system for UWB and non-UWB communication

Abstract

A method is proposed for using a vehicle system that has stored one or more identifiers. Each identifier includes a source of electrical power. The system and the one or more identifiers are configured to communicate using a UWB communication protocol and a non-UWB communication protocol. The method periodically comprises, between the system and the one or more identifiers, UWB exchanges (312) using the UWB communication protocol and non-UWB exchanges (310, 320) using the non-UWB communication protocol. Each respective period comprises, between the system and the one or more identifiers, one or more non-UWB exchanges (310, 320) and one or more UWB exchanges (312). The first UWB exchange of the respective period begins at or after the completion of the first non-UWB exchange (310) of the respective period.No UWB exchange during the respective period coincides with any non-UWB exchange during the respective period. The process provides improved utilization of the vehicle system. [Fig. 2].
