Abstract

Virtual methods utilization is increasing during vehicle development phases, to speed up the process, explore broader design space and increase the design detail before producing the first physical prototype. For complex systems like ADAS, which are inherently multidisciplinary, the use of multi-domain simulation environment is advisable: therefore, the utilization of test benches to integrate the virtual development with the first physical prototypes can increase opportunities in development and validation phases.

This work focuses on the development of a test bench and a test scenario for testing the Lane Centering system in all its components. Using a steering bench, capable of reproducing forces on the real steering system, and a camera in the loop bench, the LCA system has been entirely implemented on the static simulator and validated in virtual high-fidelity scenarios, reproducing a real test track.

Firstly, the testing apparatus construction and calibration is described. Secondly, the scenario creation procedure is shown. Lastly, various evaluation tests are carried out on the simulator, following the same methodologies as if the system is mounted on a real vehicle.

The proposed bench and testing methodologies has resulted capable of accurately reproduce the key performance index of the real system, allowing its complete assessment on the static simulator, thus broadening the design space, allowing for development time and cost reduction.
