Lane Centering Control Tuning for EPS Steering Delay

The patent applies preliminary action by developing a simulation environment and determining transfer functions before actual in-vehicle testing. The methodology involves creating virtual models of the EPS system and ADAS controller, then tuning parameters in the simulation environment first. This preliminary simulation-based parameter tuning reduces the need for extensive iterative in-vehicle testing, thereby decreasing development time while maintaining reliability improvement goals.

The patent applies copying by creating a virtual copy of the ADAS system through simulation environments. Instead of directly testing and tuning parameters in the actual vehicle through extensive iterative testing, the methodology creates digital models and transfer functions that replicate the system behavior. Parameter optimization is performed on these copies first, then validated with minimal actual vehicle testing, thereby achieving manufacturing precision while reducing device complexity and testing resource requirements.

The patent applies feedback by establishing a closed-loop process where simulation results are continuously compared with actual in-vehicle test data. The methodology involves determining transfer functions from real vehicle data, using these to build simulation models, tuning parameters in simulation, then validating and refining the models based on actual testing feedback. This iterative feedback mechanism ensures model accuracy improves to match the required measurement precision while maintaining high development efficiency through simulation-based tuning.
