“…The confidence drive level could be neglected considering the lack of a driver, and the fun to drive could be transformed to “fun to ride”, considering the subjective feel of the passengers and how they perceive the ride in addition to the motion comfort. A metric able to capture the subjective feel of the occupants is the perceptible roll index (

), as proposed by Trivedi et al [ 34 ]. The metric (

) combines the most common metric for roll performance, i.e., the roll gradient and the position of the passengers.…”

Automated vehicles are expected to push towards the evolution of the mobility environment in the near future by increasing vehicle stability and decreasing commute time and vehicle fuel consumption. One of the main limitations they face is motion sickness (MS), which can put their wide impact at risk, as well as their acceptance by the public. In this direction, this paper presents the application of motion planning in order to minimise motion sickness in automated vehicles. Thus, an optimal control problem is formulated through which we seek the optimum velocity profile for a predefined road path for multiple fixed journey time (JT) solutions. In this way, a Pareto Front will be generated for the conflicting objectives of MS and JT. Despite the importance of optimising both of these, the optimum velocity profile should be selected after taking into consideration additional objectives. Therefore, as the optimal control is focused on the MS minimisation, a sorting algorithm is applied to seek the optimum solution among the pareto alternatives of the fixed time solutions. The aim is that this solution will correspond to the best velocity profile that also ensures the optimum compromise between motion comfort, safety and driving behaviour, energy efficiency, journey time and riding confidence.

“…Yamaguchi et al (8) showed that the difference in the holding ability of the seat affects the roll feel. Trivedi et al (9) showed that the roll feel differs not on the absolute magnitude of the roll angle but depends on the distance between the driver's seating position and the roll axis. Yoshioka et al (10) mentioned that the difference in G-Vectoring Control (GVC) could cause a difference in the roll-pitch related vehicle posture and depending on the closedloop of the driver-vehicle system, the steering operation also differs.…”

This paper presents a study to quantify the difference in roll feel experienced by the driver with a change in damper characteristics between "comfort" and "sport" mode. The vehicle and driver's motion are measured during the double lane change maneuver. In "sport" mode, the timing of steering operation was found to be faster (P = 0.0456), which can be explained by the driver being able to make quick upper body corrections to resist the slow vehicle roll motion. This difference in steering operation because of the man-machine feedback system can be considered as an objective measure to quantify roll feel.
