Claim 23:
24. The improved auto-chocking enabled cargo dolly of claim 1 further comprising a transceiver disposed on the dolly frame and a plurality of proximity sensors disposed on one side of the dolly frame, wherein each of the proximity sensors being operative to detect a relative distance between the one side of the dolly frame where the each of the proximity sensors is disposed and a cargo loader external to the dolly frame, wherein the proximity sensors being operatively coupled to the transceiver to provide proximity sensor data indicating the relative distances between the one side of the dolly frame and the cargo loader as detected by each of the proximity sensors; and
wherein the transceiver being further operative to
receive the proximity sensor data from each of the proximity sensors over a period of time,
determine when the relative distances between the one side of the dolly frame and the cargo loader meets a threshold alignment configuration for the dolly frame and the cargo loader based upon the proximity sensor data over the period of time, and
responsively cause the hub-based chocking assembly to hold the at least one of the wheels in place by engaging the braking hub extension to hold the braking hub extension in place when the relative distances between the one side of the dolly frame and the cargo loader meets the threshold alignment configuration for the dolly frame and the cargo loader.
