Mercedes-Benz has patented a novel solution to address a growing issue in the electric vehicle market: motion sickness among passengers.
While traditionally associated with winding roads, motion sickness is increasingly reported by individuals traveling in electric vehicles. This unexpected challenge is prompting automakers to seek innovative solutions to enhance passenger comfort. The growing prevalence of EVs and the unique driving experience they offer are driving the need for these advancements.
Research indicates that the issue stems from a disconnect between the sensory information received by the brain in EVs compared to traditional combustion engine vehicles. As William Emond, a doctoral student researching motion sickness at Université de Technologie de Belfort-Montbéliard in France, explained, “The brain cannot accurately estimate the forces of movement because it relies on prior experience in other types of cars.”
The human body has become accustomed to the sounds and vibrations of gasoline and diesel engines over decades, providing cues that prepare it for movement. Electric vehicles, with their near-silent operation and smooth acceleration, remove these familiar signals. This, combined with features like aggressive regenerative braking and one-pedal driving, can create a sensory mismatch, leading to nausea.
Mercedes-Benz Patents System to Combat EV Motion Sickness
Mercedes-Benz has filed a patent for a system designed to mitigate this issue by simulating the sensation of movement through a combination of interior lighting and airflow. As reported by CarBuzz, the proposed system utilizes strategically placed air vents that adjust airflow intensity based on the vehicle’s speed and acceleration.
The patent, registration number 1020251092435, also details the use of ambient lighting to provide additional visual cues. The system would alter light color during acceleration and braking, and employ dynamic patterns and directional signals to create a more intuitive sense of motion. Further details on the technology can be found on the DPMAregister.
While Mercedes-Benz is not the first automaker to explore solutions to this problem, the patent underscores the growing recognition of motion sickness as a significant challenge in the EV transition. As AutoBlog notes, a patented technology does not guarantee its implementation in production vehicles, as patents often serve to protect intellectual property rather than ensure immediate product development.
