Autosar refers to events and triggers in its UML profile, and I'm confused really what the difference is between the two. It seems like a trigger can be of Call, change, timed, or signal. Those are clear to me, however, why would we need an extra event for all this? It seems like a trigger is the event.

From the UML 2.5 specs:

13.4.11 Trigger [Class]
13.4.11.1 Description

A Trigger specifies a specific point at which an Event occurrence may trigger an effect in a Behavior. A Trigger may be qualified by the Port on which the Event occurred.
