SYSTEMS AND METHODS FOR ULTRA-WIDE BAND BASED VEHICLE SENSING

A vehicle including an ultra-wide band (UWB) transceiver is disclosed. The UWB transceiver may be configured to operate in a first mode and a second mode. The UWB transceiver may be configured to perform phone-as-a-key (PaaK) localization in the first mode and radar sensing in the second mode. The vehicle may further include a processor configured to activate the UWB transceiver in the first mode. The processor may receive a trigger signal to switch the UWB transceiver from the first mode to the second mode. Responsive to receiving the trigger signal, the processor may cause the UWB transceiver to transmit a radar pulse signal and receive a radar response signal reflected from a target located inside the vehicle. Based on the response signal, the processor may determine a sitting area profile and an occupant presence on a sitting area, and perform sitting area adjustment.
