Sebastian,

there are a few flaws in your model:

1. OnArrival is not fired, if the AGV passes the CP, but only, if it gets to a Stop.
From Control Point Help:

On Arrival

Fired at an AGV's arrival at the control point, i.e. when the AGV has decelerated to stop at the control point, either because it could not allocate further ahead or if the control point is the final destination.

2. Your Event Triggered Source is set to listen to OnEntry, which is fired if an item enters the CP. The AGV does not enter though:

On Entry

Fired when an object (usually a flow item) is moved into the control point.

3. The closest you would come to trigger an event would be OnPreArrival which is fired shortly before the AGV reaches the CP to decide whether is has to decelerate:

On Pre Arrival

Fired at an AGV's pre-arrival to the control point, i.e. the point at which the AGV would start to decelerate to stop at the control point if needed. On Pre Arrival is fired prior the AGV allocating further ahead or when the AGV starts decelerating to its final destination.
