Automatic Pressure Regulator Presented by: –Jeremy Wilson

Highway Safety A problem millions of people everyday deal with. If you yourself are not faced by it, loved ones will be

Tire Debris Debris left on the road Example of operating trailer, inside tire failed, destroying second tire.

Statistics: Arizona Highway DOT Study –79 auto accidents/year due to objects on road –5400+ Tractor Trailer accidents Under inflated Tractor-Trailer Tires a primary factor –Increases belt separation –Increases heat and friction stress –Increases roll-over 0.45 g reduced to 0.40 g

Proposed Solution Automatic Pressure Regulator –Constant monitoring of tire pressure –Automatically corrects tire pressure outside normal range –Trending of pressure correction to indicate more severe problems

System Proposal Driver Information Center Regulator Tire Coupling Compressor – Belt Driven from Engine Computerized Control System Press Gage

Pros Increased Highway Safety –Reduced number of rollovers –Less highway debris causing automobile accidents Other Benefits –Better fuel efficiency –Reduced Maintenance Cost Prevent over/under inflating of tires by Human error

Cons Retro fitting existing equipment Legal liability if system fails Requires buy-in from both Rig manufactures and Trailer manufactures to be successful

Conclusion l Significant statistics prove that under/over inflated tires negatively effect highway safety l Every highway traveler would benefit l Highway safety would improve l Increased Highway Safety is a reality with the Automatic Pressure Regulator
