BAE Systems: Autonomous System Navigation, Driver Augmentation

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.

Mission 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

Problem Statement

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

Background Research

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.

CONOPS

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

Short-range: any stopping will require split-second 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 Flaws

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

Design Benefits

Manageable cost Layered detection capabilities Suggested avoidance path Model Brochure
