Abstract
Example vehicle restraint apparatus and methods of operating the same are disclosed herein. An example method includes moving a barrier via a vehicle restraint drive unit relative to a main body proximate the dock between a fully extended position to block the vehicle, a fully retracted position to release the vehicle, and a plurality of intermediate positions between the fully extended position and the fully retracted position; monitoring a status of the barrier as the barrier moves through the plurality of intermediate positions; comparing the status to a reference value; determining that an event has occurred based on the comparison of the status and the reference value; and providing an output in response to determining that the event has occurred.
