To enhance lateral active safety in intelligent connected vehicles, the identification and definition of unintended functional safety scenarios for the Electric Power Steering (EPS) system are integrated into system design and development process. By combining scenario domain analysis, equivalence partitioning, and boundary value analysis with the deconstruction of vehicle model variants and lateral motion scenarios related to EPS, more potential hazardous operational scenarios are expanded from known operational scenarios. Meanwhile, the Driver-In-the-Loop (DIL) system based on hardware-in-the-loop simulation is utilized. Relying on its advantages of “driver-vehicle-environment” closed-loop, more unknown risk scenarios are transformed into valid known scenarios. Subsequently, the existing safety technical requirements are optimized and the overall performance of the EPS system is further improved.
