In-rest vehicle proximity systems with real-time transmission lock

摘要

Each year there are several serious accidents caused by larger equipment running over smaller equipment and personnel-some of them are fatality events. Based on MSHA, the most run over accidents have occurred when the equipment moves from a rest condition. Usually this kind of incident is because the operator assumes incorrectly that the area around the vehicle is clear and the operator sets in motion the vehicle from a rest condition causing the incident. These Incidents resulted in lost of lives, equipment, and production time. The envisioned solution is to inhibit the vehicle ability to move if the surrounding area is not cleared. The proximity warning and transmission locking mechanism system described in this paper involves the development of an in-rest vehicle proximity system (iR-VPS), and the design of a simple transmission lock placed in haul trucks. From 1984 to 2003, there were eight fatal incidents in the U.S. and dozens of serious accidents that could be prevented with the use of a vehicle proximity system and a transmission lock.
