본 연구에서는 BBW 시스템의 핵심부품인 전ㆍ후륜 EMB의 단품 해석모델을 개발하고, 이를 적용한 전차량 해석모델을 개발하였다. EMB 단품 해석모델은 다물체동역학 해석 S/W인 ADAMS를 이용하여 개발하였으며, 마찰이 없는 이상적인 상태에서의 이론적인 계산결과와 비교를 통해 모델의 구성을 검증하고, 실제 H/W의 Dynamometer 시험결과와 비교를 통해 최종 모델의 적합성을 검증하였다. 또한 개발된 전ㆍ후륜 EMB 해석모델을 전차량 해석모델에 적용하였으며, 주행시 제동 시뮬레이션을 수행하여 EMB 시스템의 제동 성능을 분석하였다.

Automobile is being required electric energy increasingly because of using more and more electric devices. Therefore implementation of the 48V power system is being lead by some major European automobile makers. If the 48V system is applied, the power circuit of EPS(Electric Power Steering) should be developed, compatible with the new power system. R-EPS is one of various EPS types and mainly applied to heavy-duty class sedan vehicles, necessary for the high steering torque. In this paper, performance of R-EPS using 48V under development is tested in the static steering state. Also it is compared and evaluated with the conventional 12V R-EPS.

This paper is focused on simulation and verification of the EMB(Electro Mechanical Brake) system newly developed by the Mando Corporation. In this paper, the virtual model was made in the dynamic analysis software, ADAMS and its verification was achieved by the correlation between the result of an experiment and the simulation result. The correlation in the static state was achieved by the comparison between the result of the experiment using the Load Cell and the simulation result. In the dynamic state the correlation was achieved by the comparison between the braking torque of the dynamometer test and the simulation result. As the result of this process, the virtual model used in this simulation is verified that it is reasonable to be applied to other EMB systems.
