Abstract: This paper presents the study on the effects of lateral vehicle dynamics parameters on motion sickness of the passengers inside. Motion sickness is induced by low-frequency whole-body vibration. The frequencies and the amplitudes of whole-body vibration can be changed by changing the parameters of a conventional suspension system in a design phase or by changing the parameters of a semi-active or active suspension system during vehicle movement. By doing so, one can reduce the negative effects either by changing the vibration frequency or by reducing the vibration amplitude. For the purpose of the study, a vehicle model was developed using MATLAB to simulate the lateral dynamics with different suspension setups and to find the optimal one, which will be the most favourable to the passengers in terms of motion sickness induction. Presented methodology gave an insight into potentials to reduce the motion sickness incidence. The possibilities for methodology improvement are discussed and some guidelines for further investigations are given.
