Abstract
In this paper, a real-time multibody vehicle dynamics and control model has been developed for an intelligent vehicle simulator. The simulator consists of a scenario module for preceding vehicle motion, a control module including ACC (Adaptive Cruise Control) logic and a throttle/brake switching logic, and a real-time multibody vehicle dynamics module. The real-time multibody vehicle model has been developed based on the subsystem synthesis method. To see the effectiveness of the developed model, various ACC simulations such as preceding vehicle following, cut-out, stop-and-go have been carried out. The CPU times taken for the simulations have been also measured to see whether the developed model meets the real-time requirements.
