Abstract
Detection and correction of obstruction of vehicle wireless anchor points within a vehicle is performed. A wireless environment of a cabin of the vehicle is characterized using one or more ultra-wideband (UWB) transceivers of a phone-as-a-key (PaaK) system of the vehicle, the characterizing including to compute an initial characterization of paths and signal strength between a transmitter and a receiver of the one or more UWB transceivers. The wireless environment is periodically remeasured to compute an updated characterization of the paths and the signal strengths. Responsive to changes in the wireless environment as compared to the initial characterization indicating an impairment of in-cabin presence features, the impairment is remedied by switching which of the one or more UWB transceivers are used to perform the characterizing.
