Abstract

nd the steering force must be maintained even if the EPS fails during the autonomous driving mode. For this purpose, all electronic components of EPS must be designed to be robust and redundant, and therefore HW and SW technologies are required for operating systems. HW technologies adopt the duplication technology of EPS electric elements and SW technologies adopt control method and fail operation technology for operating the redundant elements. In this paper, the performance of the system was verified by comparing the newly developed EPS with the conventional EPS (eg, system output evaluation and actual vehicle steering evaluation).
