  1. Team 2 Marty, Zach, Jake, and Tim CONVOY SAFETY

  2. Abstract • There are obstacles that exist on the roadways that may lead to accidents. Our goal is to design a system that will detect these obstacles early enough to prevent these accidents from happening, rather than reacting to them. We will use current technology to create the system that will incorporate thermal imaging and a global positioning system.

  3. Problem Statement • The systems used to make driving safer are designed to react to an accident, rather than prevent them from happening. • Vehicles on the road are unable to detect harmful obstacles and potential collisions with other vehicles, thus getting involved in sometimes fatal accidents. • Convoys often travel in close proximity (5m apart) at speeds of 55 mph on damaged roadways.

  4. Mission Statement • Product Description • A system for maintaining formation with a convoy of vehicles a distance of 5 meters apart and for detecting other vehicles and or obstacles on the road preemptively to avoid collisions while traveling at approximately 31 mph. The sensor will be originally designed for HMMWV’s used in military operations and adapted for regular vehicles such as cars, trucks, and vans. The system will alert the driver either visually or by an audio device as to the approaching danger. The system may use one or more of the following: radar, ladar, thermal imaging, or spectroscopy. The system is not limited only to these sensors.

  5. Mission Statement • To create an effective system that meets the following requirements: • Detect obstacles upcoming on the roadway • Alerts the driver of upcoming obstacles with enough time to react safely • Regulates speed of vehicle to remain specified distance behind other vehicles in convoy • Works at high velocities (up to 55mph) • Works in all weather conditions without flaw • Looks like a professional tool. • Undetectable by enemy forces. • Easily produced/manufactured. • Durable. • Seen by all passengers. • Efficient and convenient power • Works in all weather conditions. • Easily replaced. • Easy to set up and use. • Compact. • Multifunctional • GPSNight Vision

  6. Mission Statement • Primary Market • The United States Military’s convoy deployment in conflict areas where multiple vehicles travel together at high velocities where roadways may contain obstacles • Secondary Market • Any American consumer that wants to purchase a safer vehicle • Law Enforcement

  7. Mission Statement • Assumptions • The technology is currently available to build these systems • There is a high demand for this product • Driving can be made safer using a detection system • The system will be cost-effective • Consumers as well as military convoys want to have safer vehicles to avoid accidents • The system will work up to its full potential in all weather conditions • The system cannot be overridden by enemies in a military aspect

  8. Mission Statement • Stakeholders • United States Government • United States Military • User • Retailer • Sales Force • Production • Service Center

  11. Brainstorming • After collecting information, we came up with the following ideas: • Hydraulic system • Force field • Bigger wheels • Spotlight • Nightdriver • Collision Mitigation Braking System • Autonomous Cruise Control • GPS

  14. Description of Best Design Our system will use what is currently available to the military, as well as incorporate another system. The GPS system used presently in the military Humvees is known as FBCB2. It uses satellites to determine locations on vehicles. Some Humvees are equipped with a computer that contains a touch-screen monitor and a keyboard. The monitors have digital displays. Military personnel have informed our team that they use a NODS system. This is night-vision goggles. All passengers are equipped with night vision on at least one eye. Depth perception is a problem with the goggles. The new system will add in a thermal imaging system known as NightDriver. This system has already been applied to other military vehicles (not necessarily Humvees). The system is cost-effective. A camera is placed on the frame between the two front windows at the lowest point (just above the hood) on exterior of the vehicle. The camera is protected by a air- and water-tight casing that is 3” x 5.5” x 3”. The thermal imaging lens is protected by a germanium covering that is somewhat resistant to scratches. The encasing is easily replaced. NightDriver is rated “IP66”, but can be modified to be rated “IP67”. IP67 means that the camera meets military standards. It is completely sealed and protected so that it can be completely submerged in water (or any liquid) and still maintain fully functional capabilities. There will be a video wire fed in through the frame from the back of the camera and attach to the existing monitor used by the GPS system. Because the monitor display is digital and the camera output is analog, an adaptor that converts from analog (VGA) to digital (DVI) is needed. With NightDriver installed, range of sight becomes increased by a factor of three. Minimally, the system should allow sight of obstacles that are 1500 feet (457.2 meters) away. This would allow ample time to react to any oncoming obstacle, such as a crater in the road. NightDriver runs off of the vehicle’s battery, which can range from 16-32V. Seeing that the Humvee is equipped with a 24V battery, this system would not need extra power.

  17. Cost Analysis The cost of the system for one Humvee •GPS - approx. $250,000 (over the course  of five years) – The GPS system is already existent in some of the Humvees in the field but our system will require all Humvees to be equipped with GPS •Night Driver - $3995 (includes camera, wiring, and monitor display) •VGA to DVI Adapter - $5.99 Total: approx. $255,000

  18. Summary and Conclusion Current safety systems on automobiles do not detect or alert drivers as to approaching harmful obstacles on the road such as craters, wildlife, or oncoming vehicles. Humvees in military convoys travel at close proximity approximately 5 meters apart under blackout conditions and need a system to inform them their distance from each other so that they can stay in close formation. Our goal was to design a system that satisfied this criteria. We designed a system that will be attached to the front window of the Humvee that will display an image through a touch screen monitor in the cab on the passenger side of the vehicle. The system will use thermal imaging which is effective under all weather conditions and can detect obstacles from 0 to approximately 900 meters away. The system’s total cost will be approximately $254,000. The system will be welded on to the existing steel frame of the Humvee. Overall our system satifies the criteria that BAE has outlined and it is easy to use, easy to manufacture, and alerts the driver efficiently.
