Enhancing Passenger Comfort in Autonomous Vehicles: A Vestibular System-Based Approach to Motion Sickness Evaluation

This paper presents objective indicators for motion sickness susceptibility based on vestibular function assessments using an otolaryngological approach. By correlating these indicators with motion sickness experiments conducted under real-world driving conditions, it addresses the limitations of traditional self-report methods. Motion sickness remains a significant issue across transportation modes, especially with the advent of electric vehicles (EVs) and autonomous vehicles (AVs), which may exacerbate symptoms due to unique acceleration characteristics and non-driving passenger activities. Individual susceptibility, influenced by factors such as genetics, age, and health status, highlights the need for personalized mitigation strategies. The proposed objective measures aim to improve assessment accuracy, enhance passenger comfort, and ultimately reduce motion sickness in EVs and AVs. These findings establish a foundation for future research and technological advancements, contributing to more effective prevention and management of motion sickness in future mobility.
