For the everyday traveler, the intricate workings of an aircraft may be hard to understand, but what you probably want to know above all is that you’re in a safe mode of transportation.


At EMBRAER, safety comes from testing at every stage during the creation of a plane. The Legacy 500 Iron Bird has over 50 embedded computer systems that must work together seamlessly before a test flight even leaves the ground. Because the testing cannot be accomplished in flight, system engineers at EMBRAER’s ground facility use NI VeriStand and 21 NI PXI systems to fully test the system integration of the plane’s computer systems. They create a simulation of the entire plane and test each system in real time.


When combined with LabVIEW software, EMBRAER engineers have greater functionality for system automation and validation. Using NI tools, EMBRAER reduced the development and testing process of the Legacy 500 Iron Bird by one year.

Virginia Tech recently was named the overall winner of EcoCAR: The NeXt Challenge, a three-year collegiate vehicle engineering competition sponsored by the U.S. Department of Energy and General Motors (GM). The Virginia Tech team designed and built an extended-range electric vehicle using E85 (ethanol) and capable of achieving fuel efficiency of 81.9 miles per gallon gasoline equivalent. The team used NI technology to design, prototype, validate and deploy a control strategy for the hybrid components of the vehicle.




To interface with and control the vehicle, the Virginia Tech team chose CompactRIO to act as a hybrid vehicle supervisory controller that would balance power distribution between the vehicle’s combustion and electric systems. The controller was programmed with LabVIEW, which also served as the runtime environment for the main driver display in the vehicle. The LabVIEW Statechart Module was used to create a high-level state machine control architecture for splitting torque between the hybrid components. Prior to deploying their control strategy to hardware, the team used NI VeriStand and NI PXI to create a hardware-in-the-loop simulation and validation system that evaluated the fuel and electric energy consumption of the vehicle as well as test safety features.


Sixteen North American universities participated in EcoCAR and re-engineered GM-donated vehicles to minimize fuel consumption and emissions while maintaining its utility, safety and performance. In addition to winning the overall competition, Virginia Tech won awards for Shortest 60-0 MPH Braking Distance, Best AVL Drive Quality, Best Dynamic Consumer Acceptability and Best Fuel Consumption. The team also received the National Instruments Most Innovative Use of Graphical System Design award. NI is a platinum sponsor of EcoCAR.
