Minimisation of Motion Sickness in Autonomous Vehicles

This paper presents the application of optimal control problem formulation for motion planning in order to minimise motion sickness in autonomous vehicles. The optimum velocity profile is sought for a predefined road path from a specific starting point to a final one within specific and given boundaries and constrains in order to minimise the motion sickness without compromising the journey time. For the representation of the motion sickness as a cost function to our optimal control problem, the illness rating is used. The influence of road width flexibility on illness rating and for a set of fixed journey times are investigated. According to the results, the road with flexible lateral manoeuvrability is found to provide lower sickness compared to the fixed road path. Moreover, the correlation between sickness and journey time can be represented as a Pareto front.
