Automating Restbus Simulation
In HiL setups, real ECUs need to receive valid IVN* signals to operate correctly.
Given high data streams and platform peculiarities, Restbus simulation becomes:
- time-consuming
- based on manual signal selection
- difficult to scale across vehicle models
Result: higher integration workload and inconsistent HiL turnaround.
*In-vehicle network
During his PhD at Meccanica 42, Alessio Anticaglia developed a structured, software-implemented method to parse the CAN database and streamline Restbus simulation.
The tool highlights and quantifies signal dependencies, otherwise laborious and non-trivial to detect, and outputs a fully defined Restbus
signal set, removing manual signal selection and accelerating integration.
The beneifts:
- Reduced dependency on protocol-level expertise
- Same method usable to different vehicle platforms
- Clear, repeatable signal configuration
- Fewer iterative loops
