Modeling and validation of carsickness mechanism

Numbers of researches on carsickness are less than researches on seasickness and space sickness. However, the clarification and applications of carsickness mechanism is a serious problem for the developers in pursuing vehicle comfort ability. We developed prediction model of carsickness incidence and verified to simulate Griffin\´s horizontal oscillation experiment. Our model could predict distribution characteristics of Griffin\´s "mild nausea" basically. In addition, we tried to improve prediction accuracy by reformatting model and parameter study.
