실시간 다물체 차량 동역학 모델을 이용한 ESC Hardware-in-the-loop 시뮬레이션

다국어 초록 (Multilingual Abstract)

Intelligent vehicle consists of several control systems such as ESC (Electric Stability Control), CDC (Continuous Damping Control), etc. To develop such control subsystems, extensive vehicle tests are necessary to evaluate control subsystems. To reduce the number of vehicle tests, which are mostly time consuming and costy, HILS (Hardware-In-the-Loop Simulation) is necessary. In the HIL-simulaor, the software vehicle dynamics model must be solved in real-time, and it must also reproduce real vehicle motions. In order to carry out real-time simulation, real-time multibody vehicle dynamics model has been developed using subsystem synthesis method. In this paper, the real-time multibody vehicle dynamics model has applied into the HIL-simulator constructed in KATECH (Korea Automotive Technology Institute). Performance evaluations of intelligent chassis controller such as ESC have been carried out. Fish-hook test simulations have been carried out to see the performance of the intelligent chassis controller.
