Success Story: Hydraulic Test and Simulation of Field-Installed Systems

Recently, a large industrial firm presented several hydraulic test system manufacturers with a challenge: develop a system to simulate a field installation for factory set-up and testing. Naturally everyone jumped at the chance for a line-up. Then the required system’s capabilities were outlined as follows:

How to Combine HIL with Mechanical Systems Rigs to Create Electromechanical Test Rigs

Visit WTI in Booth #7020 at the Automotive Testing Expo 2018

Meet with Wineman Technology at Automotive Testing Expo 2018, held October 23-25, in the newly expanded Suburban Collection Showplace in Novi, Michigan to learn how our expertise in building HIL systems can both meet your test schedules and achieve your requirements.

Closing the Loop: The HIL Preparedness Checklist

Guest post by Jeff Philips, Head of Automotive Marketing at National Instruments

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.  

Wineman Tech’s Automotive HIL Reference Design with Cummins, National Instruments Draws Recognition

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.

5 HIL Trends for Chassis and Body Electronics Test

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.

What is Hardware-in-the-Loop (HIL) Testing?

The Problem

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 Partners with OrangeWire Systems to Provide Switch, Load, and Signal Conditioning Products to Expedite Development of Hardware-in-the-Loop (HIL) Test Systems

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.

Case Study: Electric Parking Brake HIL and Durability Testing Using CANalytics Software

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.
