You’re ready to take advantage of the benefits of Hardware in the Loop testing. But, before you begin, there are some common roadblocks you are likely to experience when setting up a new HIL system. You can avoid these by first assessing your preparedness for this transition whether it’s a desktop system or a full testing rack.
The system, presented at NI Week 2018 by Cummins Inc. and Wineman Tech in a keynote session, was featured in a show recap article by Electronic Design.

Cummins Inc. needed a repeatable platform to test more than 60 engines, ranging from near zero emissions to diesel to natural gas. The company had already tried several hardware-in the-loop strategies to test a variety of MCUs in its flagship electric vehicle, the AEOS Truck, but needed a higher level of integration and flexibility to reduce test time, space and cost on a global scale.
According to FMI’s Automotive Electronic Control Unit (ECU) Market Assessment, the global market for ECUs – including engine, brake, suspension, and body control modules – is forecasted to grow at a strong CAGR of 7.1% through the period of 2017-2022. The race to creating smarter, safer, and cleaner cars for the mass market is tighter than ever, and with that comes the pressure to speed up the R&D cycle while still providing comprehensive, bulletproof testing that roots out potential problem areas.
Vehicles are being controlled by progressively more advanced computers called ECUs (Electronic Control Units). Testing the designs for new ECU hardware and firmware on actual cars, trucks, and airplanes is expensive, cumbersome, and sometimes even destructive. To speed development and reduce risk, engineers test their ECU designs "virtually" by using software models to simulate various physical components like engines, wheels, and sensors. However, these "models-in-the-loop" or MILs have limitations. Would you drive a car or fly in an airplane that had been designed based only on software models?
Wineman Technology has partnered with OrangeWire Systems to offer switch, load, and signal conditioning modules for the National Instruments SLSC platform. This product line works seamlessly with the National Instruments platform to provide flexible, COTS-based HIL systems for automotive, aerospace, medical devices, and other industries where real-time HIL simulation is critical for timely system development.
Akebono Brake Corporation is a global supplier of foundation brakes and brake friction materials for automotive OEM customers such as Audi, Chrysler, General Motors, Honda, Toyota, and many more. One of the new technologies they are focused on is electric parking brakes, and they wanted to update their mid-height HIL system for testing ECU brake software.
Using NI LabVIEW and a real-time CompactDAQ (cDAQ) system, we worked with Akebono to deliver an upgraded hybrid HIL tester capableof mechanical brake simulation. We also created a new full-height tester for running 24/7 durability testing on three electric parking brake systems simultaneously.
Wineman Technology, Inc., today announced that it was recognized as a National Instruments Hardware-in-the-Loop (HIL) Specialty Alliance Partner. As a longtime National Instruments Gold Alliance Partner with more than 25 years of experience, Wineman Technology was selected for its demonstrated expertise and in-house development of complete HIL systems using NI’s leading-edge commercial-off-the-shelf (COTS) technologies.
When beginning a project to create a data acquisition, control, or test system, the main two concerns are often “How can we keep costs low?” and “How quickly will it be up and running?” Unfortunately, that can lead to rushing through the most important first step: the creation of a detailed project requirements document.
