Each year new ways of alerting drivers to improve the safety of the driver are expanding. With the creation of Advanced Driver Assistance Systems (ADAS), cars can now alert the driver of potential hazards. The ERAU Team has created an acronym specific to their ADAS – IDEA. The Intelligent Driving Efficiency Assistant works on three different features to increase safety and efficiency: Smart Stop, Forward Collision Warning, and Lane Detection Warning.
Each of these features will alert the driver through the car’s interface. Smart Stop is custom to IDEA, and will improve the use of the engine based on driving conditions. The Smart Stop feature recognizes visual cues within the environment surrounding the vehicle, such as identifying common braking situations, to disable the engine and focus on regenerative braking to maximize free energy. Forward Collision Warning recognizes the closure rate of a vehicle in front of your own. If the car is within an unsafe distance, the vehicle will warn the driver to increase the distance. This feature identifies surrounding traffic and road conditions to improve powertrain efficiency of the vehicle. Lastly, Lane Detection Warning alerts the driver if the vehicle has crossed a detected lane marking without the use of a turn signal. These alerts are intended to improve awareness for a distracted driver and refocus the driver’s attention to the driving conditions at hand.
Our team lead for IDEA or ADAS, Mengshu Qing, has been working diligently with nine other teammates and the use of her training from MathWorks at the Fall Workshop to create the algorithms necessary to complete car back tracking, stop sign tracking, and distance calculations. Thanks to NXP’s generous contribution to the competition, these programs are input into NXP’s Advanced Processer which will later be inserted into the car for full use. Currently it works connected to a laptop and is managed by the passenger of a car during testing; Later being inserted into the Camaro with the result (warning indications) appearing on the interface.
Our stereo test camera captures objects including but not limited to, stop signs, speed limit signs, pedestrians on sidewalks or crossing the road, and surrounding vehicles (forward and rear). For testing, the camera seen below is mounted on the top of the car. As the stereo camera captures the environment, IDEA collects data and in turn, transmits warning signals to the driver.
The team is excited to be taking the car to Winter Workshop this week where we will be demonstrating the performance of our ADAS including lane departure, collision warnings, and the overall recognition of the car’s environment.
