2. Needs and Requirements Detect obstacles on rugged terrain Monitor Vehicles in all directions Aid obstacle avoidance and traffic Work in reduced visibility conditions Usable in extreme weather conditions User friendly and safe for vehicle operations / occupants Adaptable to various vehicle types / transportation systems

3. Conceptual Ideas • Infrared Vision • GPS (Global Positioning System) • UAV (Unmanned Aerial Vehicle) • Remote Mapping • Radar/LIDAR/Wi-Fi

4. Weighted Selection Matrices

5. IR Vision • Combines infrared goggles, or cameras, with an infrared light emitting device. • The goggles enable drivers to see in low to no visible light conditions making driving in blackout conditions a lot safer. • The IRED would increase the range and clarity of the image.

6. Global Positioning System • GPS utilizes a constellation of at least 24 medium earth orbit satellites to transmit microwave signals that are picked up by a GPS receiver • The signals would be relayed to the HMMWV before and during the mission so the convoy could view and monitor the terrain.

7. Unmanned Aerial Vehicle UAV’s are usually unmanned aerial vehicles that scout ahead for reconnaissance. These aircrafts can be either remote controlled or have a pre-set flight pattern. They would relay terrain and visual images back to the driver of the HMMWV.

8. Remote Mapping Images are transmitted via satellite to receiver in vehicle. The images are compared with the terrain around the vehicle, which allows the driver to note their position and avoid obstacles.

9. Radar/LIDAR/Wi-Fi • Use of Radar sensors, LIDAR sensors, and Wi-Fi networks between each vehicle • Modified ECU’s for each vehicle that would respond to simple commands • Laptop computers for navigators to communicate terrain and traffic

10. Radar • Is a system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects such as aircraft, ships, motor vehicles, weather formations, and terrain.

11. Wi-Fi • Is the common name for a popular wireless technology used in home networks, mobile phones, video games and more. • This would connect all the vehicles in the convoy allowing the complex data to be quickly transferred.

12. LIDAR • An optical remote sensing technology that measures properties of scattered light to find range and/or other information of a distant target. • The prevalent method to determine distance to an object or surface is to use laser pulses

13. LIDAR Image

14. Advantages • Can detect moving objects • Does not rely on previously recorded information like remote mapping and GPS • Detailed feedback given to operator

15. Disadvantages • Complex system • Heavy and takes up a lot of space • Vulnerable to attack and weather • Very expensive > $200,000 per vehicle.

16. How it Works Radar would detect vehicles at long ranges and monitor distance between convoy vehicles LIDAR would detect all terrain within 120 m LIDAR images would be displayed on a laptop or computer screen to the navigator

17. How it Works • Wi-Fi would communicate sensor info to ECU and onboard computers of all convoy vehicles • ECU would initiate braking if the Radar sensed the vehicle in front of it braking • Only one vehicle would require the Radar and LIDAR sensors
