Recent research published in the journal ‘Applied Sciences’ explores how automated vehicles can better accommodate passengers engaged in non-driving tasks, such as reading or using screens. As these vehicles become more prevalent, understanding how they affect human postural stabilization is crucial, especially since passengers may not be focused on the road. This lack of attention can lead to discomfort and even motion sickness during dynamic driving situations.
The study, led by Mojtaba Mirakhorlo from the Faculty of Mechanical, Maritime & Materials Engineering at Delft University of Technology, introduces a sophisticated multi-segment full-body human model that simulates how the body responds to vehicle motion. This model incorporates feedback mechanisms from the vestibular system and muscle spindles, which are vital for maintaining head and neck stabilization. The research specifically examined how passengers react to a “sickening drive,” characterized by a 0.2 Hz slalom motion with acceleration, revealing that the model closely mirrors human motion in these conditions.
Mirakhorlo states, “Human modeling can enable the insights required to achieve breakthrough comfort enhancements, while enabling efficient developments for a wide range of driving conditions.” This insight is essential for automotive manufacturers aiming to design seats and suspension systems that minimize discomfort. The findings suggest that active muscle control in the legs is crucial for stabilizing the trunk during high-amplitude movements, which has significant implications for seat design and vehicle motion-control strategies.
The commercial opportunities stemming from this research are vast. Automotive manufacturers can leverage these insights to create more comfortable seating arrangements and advanced suspension systems that cater to passengers engaged in non-driving activities. Additionally, companies focused on automated vehicle technology can use this research to enhance user experience, potentially reducing the incidence of motion sickness and improving overall satisfaction.
As automated vehicles continue to evolve, understanding the biomechanics of passenger comfort will be a key factor in their design and functionality. This research not only highlights the importance of human-centered design in automotive engineering but also opens the door for innovative solutions that could redefine passenger experiences in the future.
