Vehicle-mounted ranging system and method of operating the same

A method of operating a vehicle-mounted ranging system having a communication transceiver configured to wirelessly communicate with at least one external communication transceiver, at least one ultra-wideband (UWB) transceiver configured to transmit and receive ranging pulses to and from an external UWB transceiver of the at least one external communication transceiver, and a controller interfaced with the communication transceiver and the at least one UWB transceiver, the method comprising:

• communicating wirelessly with the at least one external communication transceiver to schedule transmission of ranging pulses between the at least one UWB transceiver and the at least one external communication transceiver by way of the communication transceiver under control of the controller;
• configuring by way of the controller the plurality of UWB transceivers with the schedule of the transmission of the ranging pulses;
• and
• calculating by way of the controller ranges between the at least one UWB transceiver and at least one external UWB transceiver of the at least one external communication transceiver based upon time-of-arrival of ranging pulses transmitted between the at least one UWB transceiver and the at least one external UWB transceiver of the at least one external communication transceiver.
