Motion sickness in passenger vehicles during test track operations

Area of Science:

• Human-computer interaction
• Automotive engineering
• Human factors psychology

Background:

• Automated vehicles (AVs) are transitioning drivers to passengers, potentially increasing motion sickness incidence.
• Understanding passenger motion sickness is crucial for AV adoption and safety.

Purpose of the Study:

• To quantify motion sickness in front-seat passengers performing typical activities under AV conditions.
• To identify factors influencing motion sickness, including task engagement and acceleration levels.

Main Methods:

• Fifty-two adults participated in controlled driving simulations on a closed test track.
• Motion sickness was rated during various passenger activities and acceleration conditions.
• Participant age and self-reported susceptibility were recorded.

Main Results:

• Motion sickness ratings increased with task engagement compared to no task.
• Moderate acceleration levels induced higher motion sickness than low acceleration.
• Higher susceptibility and younger age (<60) correlated with increased motion sickness.

Conclusions:

• Passenger activities and acceleration significantly impact motion sickness in AVs.
• Motion sickness susceptibility and age are key covariates influencing passenger experience.
• Addressing motion sickness is vital for the widespread acceptance of automated vehicles.
