Mission Statement � The mission of our project is to design an efficient driver assist concept for military convoy vehicles. We envision our firm becoming the leaders of this market and eventually taking the product commercial, saving countless lives.
Problem Statement � Road Conditions can be treacherous � Visibility can be poor, possibly even black out conditions � Oncoming traffic needs to be avoided � Obstacles need to be detected � Best path must be determined
Background Research � Analytical ◦ ◦ Model Max acceleration during turn: 1. 3 g’s Time for third car to catch up to first: 1. 38 sec Time for convoy to complete path: 6. 63 sec When incoming traffic is an issue: 103. 62 m to 142. 25 m
CONOPS � System Requirements ◦ Identify immediate hazards (ex. potholes, rockslides, etc. ) ◦ Identify possible, non-immediate obstacles (other motorists, animal crossings). ◦ Develop a unique strategy to avoid any immediate obstacles while also dodging any additional objects. ◦ Certain options are available, though are to be avoided if possible, such as immediately stopping until all traffic has passed. ◦ Also, certain G-force constraints must be met so no adverse effects occur on the vehicle occupants.
Design Features � Designs are made of multiple components. � Each component was itself first a concept. � Concepts were then mixed and matched to decide on a complete idea that would solve the problem.

Cost Analysis � 2 Short Range Radars: $200, 000 � 7 IR Cameras: $49, 000 � Interface Equipment: $9, 500 � Testing: $2, 880 � Installation: $600 � Total with Profit: $340, 574
Design Flaws � Short-range: any stopping will require splitsecond reaction or a slower speed � Higher speeds would complicate calculations, possibly causing accidents � Communication problems: ground clutter damaging system/ loss of communication during hard turns
Design Benefits � Large forward detection area � Easily identifies pedestrians, animals, and other vehicles � “Dummy-box” system keeps vehicles uniform, even with different functionality � LED screen used to minimize emitted light � Difficult to disrupt communications ◦ Communication also better than pure audio
Conclusions � Manageable cost � Layered detection capabilities � Suggested avoidance path � Model � Brochure
