Claim 47:
48. The improved auto-chocking enabled cargo dolly of claim 30 further comprising a proximity sensor disposed on one side of the dolly frame to detect a distance between the one side of the dolly frame and a cargo loader external to the dolly frame, the proximity sensor being operatively coupled to the electronic control module to provide proximity sensor data indicating the distance between the one side of the dolly frame and the cargo loader; and
wherein the electronic control module being further operative to
receive the proximity sensor data from the proximity sensor over a period of time,
determine when a distance between the one side of the dolly frame and the cargo loader is below a threshold cargo loader distance based upon the proximity sensor data over the period of time, and
responsively trigger the hub-based chocking actuator to 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 distance between the one side of the dolly frame and the cargo loader is below the threshold cargo loader distance.
