Abstract
A method includes receiving a corresponding synchronization packet captured by a receiving UWB radio associated with a zonal controller of a vehicle. The synchronization packet includes a respective reference timestamp that includes a time of a master clock when a transmitting UWB radio transmitted the corresponding synchronization packet. The method also includes determining a respective received time stamp for the corresponding synchronization packet and obtaining a reference ToF value. The received time stamp includes a time of an internal clock of the zonal controller when the corresponding synchronization packet was captured by the receiving UWB radio. Based on the respective reference timestamp, the respective received time stamp, and the reference ToF value, the method also includes determining the internal clock of the zonal controller is not synchronized with the master clock and adjusting the internal clock to synchronize the internal clock of the zonal controller with the master clock.
