The effect of roll and pitch movements of passenger cars on motion sickness

As vehicle automation progresses, there is a growing concern regarding the potential increase in motion sickness (kinetosis) due to increased sensory conflicts. To gain a better understanding of the causes and effects of kinetosis in passenger cars in order to develop suitable countermeasures, this paper examines the influence of roll and pitch motion of passenger cars on kinetosis during lateral and longitudinal acceleration manoeuvres. A study was conducted with 28 participants who took part in two car experiments. Each participant experienced two different magnitudes of the same rotational oscillation, representing a minimum and maximum level of rotational motion. The visual stimulus was held constant to allow for an isolated examination of the influence of the vestibular stimulus. By analysing the mean MISC scores, individual MISC rates, and survival times, the paper demonstrates that changing the magnitude of pitch or roll motion in passenger cars has no effect on kinetosis. Therefore, the potential for mitigating motion sickness in passenger cars through measures aimed at reducing pitch or roll motion is considered to be low.
