Flight on the ground early with no call. As we were getting into position; agent had walked over to the truck to get them to move the truck. No one was in the truck. Ramp had notified [driver] just before to move the truck when they saw it. The Aircraft was still approaching because the pilot was watching the self-park light [which was] green. [One ramp worker] attempted to stop him but they did not see him so [another ramp employee] ran out in front and they still were watching the green light. Finally; [the ramp employee] threw his glove at the windshield to get their attention. That is when the aircraft made an abrupt stop. The truck was moved and the flight blocked in. This aircraft had winglets.
Ramp employee reported a truck was in the ramp envelope area while an aircraft taxied in with the self-park light showing green.
