Electric vehicles (EVs) are known for their silent acceleration and instant torque, which can be a thrilling experience for some drivers. However, for others, especially those prone to motion sickness, the lack of noise and strong surge of acceleration can exacerbate feelings of nausea and discomfort.
A study conducted at France’s Université de Technologie de Belfort-Montbéliard found a direct correlation between strong regenerative braking in EVs and passengers feeling sick. Regenerative braking occurs when the vehicle slows down using its electric motors, and the more powerful the regen, the higher the likelihood of passengers experiencing nausea.
William Emond, a PhD student researching car sickness, explains that the brain of EV passengers is not accustomed to the noiseless acceleration and lack of traditional cues like engine revs and vibrations. This unfamiliar motion environment can catch the senses by surprise and lead to feelings of sickness.
To address this issue, artificial signals such as visual, audible, or vibrational cues could be implemented in EVs to provide passengers with a better understanding of the vehicle’s movements. Mercedes-AMG’s upcoming EV, which simulates the sound and rumble of a V-8 engine, may serve as a potential solution for those susceptible to motion sickness.
Personal experiences also highlight the challenges of motion sickness in EVs, with some individuals feeling queasy while driving certain models like the BMW i4 M50. These insights emphasize the need for further research and development in creating a more comfortable and nausea-free experience for all occupants in electric vehicles.
In conclusion, while EVs offer numerous benefits in terms of performance and sustainability, addressing the issue of motion sickness is crucial to ensure a pleasant and comfortable driving experience for all passengers. By incorporating innovative solutions and technologies, automakers can enhance the overall ride quality in electric vehicles and make them more accessible to a wider range of individuals.
