Integrated control of direct yaw moment control and active suspension system for 4wd vehicles

摘要

Recently, due to the increasing needs of active safety systems, various chassis control systems have been introduced in the automotive industry. Such as ABS (anti-lock braking system), ESP (electronic stability program), AFS (active front steering), VDC (vehicle dynamics control system), ASS, DYC and ARS (active roll control system) are being applied to achieve greater performance. Dongshin [1] developed the MANDO ESP, and study the performance of ESP system in the emergency situation such as the final oversteer and understeer. Frequently, these chassis control systems are always designed and developed independent of each other, even though their dynamics often interact. For future prospects, the effect of chassis control systems can be further increased by the integration of those chassis control systems.
