Active safety systems are being developed with the aim of helping to reduce the number of traffic accident casualties to zero, but the creation of more effective systems requires analysis of driving behavior and verification of the effectiveness of accident prevention technologies. For this reason, a driving simulator (DS) has been developed that reproduces realistic scenarios of Japanese city streets where accidents are prevalent. The DS consists of a mock vehicle, a turntable inside a dome, a 6-degree-of-freedom (DOF) hexapod system, shakers (vehicle vertical vibration actuators), and a translational motion system capable of moving 35 meters longitudinally and 20 meters laterally. The system is also capable of projecting images of actual city streets and highways onto a 360° spherical screen. As a result, it can reproduce a driving environment that is virtually the same as the real traffic.
