Automatic wireless vehicle anchor correction

A system for detection and correction of obstruction of vehicle wireless anchor points within a vehicle, comprising:

• one or more UWB anchors of a PaaK system of the vehicle;
• and
• a controller in communication with the one or more UWB anchors and configured to:
• perform a handshake operation between a first UWB anchor of the one or more UWB anchors and a second UWB anchor of the one or more UWB anchors to establish visibility between the one or more UWB anchors,
• characterize a wireless environment of a cabin of the vehicle using the one or more UWB anchors, the characterization including to compute an initial characterization of paths and signal strengths between a transmitter and a receiver of the one or more UWB anchors,
• periodically remeasure the wireless environment to compute an updated characterization of the paths and the signal strengths, and
• responsive to changes in the wireless environment as compared to the initial characterization indicating an impairment of in-cabin presence features, remedy the impairment by switching which of the one or more UWB anchors are used to perform the characterization.

A non-transitory computer-readable medium comprising instructions for detection and correction of obstruction of vehicle wireless anchor points of a PaaK system of a vehicle that, when executed by a controller in communication with one or more UWB transceivers, causes the controller to perform operations including to:

• perform a handshake operation between a first UWB transceiver of the one or more UWB transceivers and a second UWB transceiver of the one or more UWB transceivers to establish visibility between the one or more UWB transceivers for an initial characterization of a cabin of the vehicle,
• utilize a transmitter and a receiver of the one or more UWB transceivers for performing in-cabin presence features, including one or more of intrusion detection or child presence detection within the cabin,
• characterize a wireless environment of the cabin of the vehicle using one or more UWB transceivers, the characterization including to compute an initial characterization of paths and signal strengths between the transmitter and the receiver of the one or more UWB transceivers,
• periodically remeasure the wireless environment 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 the in-cabin presence features, remedy the impairment by switching which of the one or more UWB transceivers are used to perform the characterization.
