A driving Simulator is very useful instrument not only to test the device of future cars but also to evaluate the HMI(Human-Machine Interface). It has already been developed since 1970's. Most driving simulators has the motion platforms which are installed below the cabin for realistic driving feel. However this causes undesirable reverse force during sudden maneuvers. During a sudden left hand turn, the driver is expected to experience a pulling force toward the right due to centrifugal forces. However at the start of the tilting motion, the driver experiences a force in the opposite direction for a short period of time due to inertial accelerations. This is responsible for the simulator sickness which is the major shortcoming of driving simulators. This paper describes and introduces a new type motion platform, the inverted driving simulator. With the inverted motion platform, the initial force at the start of the tilt and the resulting force due to gravitational pull after the motion platform is tilted are in the same direction. Therefore, with proper motion modulation, the driver can be made to feel the desired force in the correct direction right away form the beginning of motion.
