[0066] In this embodiment, the ECU 70 communicates with the base sensor 47 and the base latch unit 44 to lock the base rod 24 in the base connector 46 when the base rod 24 is inserted therein at a first distance. The base sensor 47 is configured to sense the base rod 24 relative to the base connector 46 when the base rod 24 is inserted therein. In addition, the base latch unit 44 is configured to lock the base rod 24 in the base connector 46 when the base rod 24 is inserted therein at the first distance to fix the base portion 22 to the receiving portion 42 defining a locked base position. Therefore, when the base rod 24 is inserted into the base connector 46, the base sensor 47 is configured to sense the base rod 24 at the first distance from the base rod 24, thereby activating the base latch unit 44 to lock the base rod 24 therein. During operation, when the base sensor 47 senses the base rod 24 in the base connector 46 at or within its first distance, the base sensor 47 may send a locking signal to the ECU 70. In turn, the ECU 70 sends a signal to the base latch unit 44 to lock the base rod 24 within the base connector 46, thereby securing the base portion 22 to the receiving portion 42 in the locked base position.

[0067] In addition, the base sensor 47 is configured to monitor a locked base position. That is, by sensing that the base rod 24 is within its first distance, the base sensor 47 is able to monitor the locked base position between the base portion 22 and the receiving portion 42. In this embodiment, when the base rod 24 is within the first distance from the base sensor 47, the base sensor 47 can send a confirmation signal to the ECU 70 indicating that the locked base position has been reached and / or is being maintained. In the event that the locked base position changes, the base sensor 47 can send a warning signal to the ECU 70 indicating that the base portion 22 may need to be repositioned relative to the receiving portion 42. In this example, the ECU 70 can be configured to notify / warn the driver or occupant in the vehicle through the cabin display unit 72.
