Optimize your ECU validation with HIL-SIL hybrid simulations

This video introduces the concept of hybrid simulations, in particular the integration of software-in-the-loop (SIL) and hardware-in-the-loop (HIL) test methods for electronic control units (ECUs). Learn how the VEOS-SCALEXIO coupling solution overcomes the challenges of varying simulation speeds and the necessity of maintaining synchronization between both simulators, SIL and HIL. Andre, our Product Manager, shares our demonstration that showcases the functionality of adaptive cruise control and autonomous emergency braking systems, highlighting the advantages of this hybrid approach for automotive simulations.

A: It allows developers to start with virtual testing and progressively integrate real hardware components, providing a flexible and scalable testing approach. Q2: How do VEOS and SCALEXIO communicate in the hybrid setup? A: They are connected via an Ethernet cable using the VEOS SCALEXIO Coupling Solution, which synchronizes data exchange in real time. Q3: Why is real-time synchronization challenging in HIL-SIL hybrid simulations? A: Because SIL simulations can fluctuate in speed due to operating system resource allocation, while HIL requires strict real-time execution. Q4: What kind of delays can be expected in the hybrid simulation? A: Maximum delays of 5 to 10 milliseconds have been observed, which is acceptable for systems with cycle times of 10 milliseconds or longer. Q5: Can this hybrid approach be used for safety-critical real-time systems? A: It depends on the system’s timing requirements; for very fast cycle times or safety-critical timing, further optimizations may be necessary. ******************** Optimize your ECU Validation with HIL-SIL Hybrid Simulations #HybridSimulations #SIL #HIL #VEOS #SCALEXIO
