Abstract
Traffic accidents, traffic congestions, and environmental issues are serious problems in the current automobile society. In order to solve these problems, research and development for transportion are being done under the name of ITS. In the ITS technology, a driving simulator is developed for fundamental studies of human performance while driving in various situations. The simulator system used in this study has six-degrees-of-freedom, and the motions are controlled by six servomotor-powered electric actuators. At present, the simulator motion system can only simulate vehicle accelerations. In order to obtain better simulation, this paper discusses vehicle vibrations created by road surface irregularities added to the simulator system.
