A Closer Look at Hardware-in-the-Loop Focus on Challenges and Requirements

Camarillo, CA,

Stringent safety standards and fuel efficiency improvements have led the change for smarter automotive testing. The need for faster systems, quicker response time, and overall speed has propelled the electronic data transfer industry to unprecedented developments in high-performance automotive testing systems.

Standard electrical infrastructure components are now expected to execute at higher performance standards.  In automotive manufacturing, the area that drives the power is automotive testing. Engineers need a fast and accurate method to test functionality while eliminating potential failure points well before production begins.

Driving the HIL Simulation Method

With the innovation of electronic control units (ECUs) as standard embedded systems in new cars, hardware-in-the-loop, also known as HIL simulation is the testing standard for electrical simulation.

Usage of HIL enhances the quality of the testing process by increasing the scope of testing. Ideally, an embedded system would be tested against the real automotive manufacturing plant, but most of the time the real plant itself imposes limitations in terms of the scope of the testing.

HIL simulation bypasses these limitations and is a key step in developing human factors, a method of ensuring usability and system consistency using software ergonomics, human-factors from research and design.

High-speed data transfer is a key factor to fast and accurate HIL simulations. Modular connectors are ideal for automotive testing applications. Features such as high mating cycles, high vibration resistance, high level of failure safety and contact security are critical for the HIL simulation process.
