Hardware-in-the-Loop (HiL) simulation solution

Simulate realistic conditions for ECU testing

Testing ECUs (electronic control units) plays a crucial but cost intensive and extensive role for successfully developing automated vehicles.

With our Hardware-in-the-Loop (HiL) simulation solution, you can test the functions, system integration, and communication of ECUs in a simulated environment under realistic conditions to validate your ECUs and their functionality.

Built with modular, proven-in-use hardware and software, you can profit from a scalable system and high processing power that allows the parallel replay of multiple sensor streams.

Benefits

Improve product quality

Safely test any given situation in a simulated environment and foster quality control. Our solutions are compliant with the latest AUTOSAR version, meeting the highest criteria of mass production software.

Maximum efficiency

Validate the ECU functionality through processing real driving scene data and shorten the time to market despite more and more complex vehicle network architectures. Profit from high processing power that allows the replay of multiple sensor streams such as camera, LIDAR, or vehicle bus communication.

High level of safety through reproducibility

Simulated tests are easy to reproduce and allow for the detection of errors already during predevelopment, playing a crucial part in bringing vehicles into mass production. Our proven-in-use rest bus simulation plays a major part in this task.

Ready to use, customizable turnkey solutions

A solution built from interlocking and proven-in-use hardware and software products, ready to use right from the start. Easily customizable with specific add-ons.
