概述
Tier 1 suppliers face rising pressure as software‑defined vehicles (SDVs) demand earlier, faster validation. In this video, Janek Jochheim and Erik Panke explore how Software‑in‑the‑Loop (SIL) helps teams front‑load testing, run scalable vECU simulations, and free up HIL capacity – while aligning with OEM requests for virtual ECUs and standardized exchange formats (e.g., FMI/FMI‑LS).
Key takeaways
- Why OEMs are shifting validation left and asking suppliers for vECUs.
- How SIL reduces bench bottlenecks and enables parallel test execution – on PCs or in the cloud.
- Why SIL and HIL work better together than either alone.
- Standards that simplify supplier – OEM collaboration (FMI/FMI‑LS).

FAQs
Q1: What is the main benefit of bridging SIL to HIL testing?
A1: It allows early validation of ECU software in a virtual environment and seamless transition to real hardware tests without rewriting test cases, improving development efficiency and reliability.
Q2: How accurate is the battery cell voltage emulation in the HIL setup?
A2: The system uses high-end hardware capable of 0.3 millivolt accuracy with galvanically isolated power supplies for precise and safe signal generation.
Q3: Can this setup test production-level ECU firmware?
A3: Yes, the virtual ECU includes application and basic software components, enabling testing close to production code.
Q4: How does automation improve the testing process?
A4: AutomationDesk enables repeatable, block-based test cases with automatic execution and reporting, reducing manual intervention and increasing test consistency.
Q5: Are other battery-related test cases supported besides undervoltage testing?
A5: Yes, tests for cell overvoltage, cell balancing, and pre-charge circuit functionality are also supported within the same framework.
Q6: Can this testing approach be adapted to other vehicle types?
A6: While demonstrated on a low voltage scooter, the methodology and tools are applicable to a wide range of battery management systems in automotive and other sectors.
