With electric cars that rise in popularity in the world – in 2024, 22% of new car sales Around the world, electric vehicles, compared to 18% in 2023 – an increasing set of studies and an increasing number of people have found that they feel more traffic in electric vehicles than in traditional petrol or diesel cars. Anecdotes of feel sick In the passenger or rear seat of electric cars Litter social networkslike that questions Being potential buyers.
There is a scientific explanation on the reason why a person may feel more sick in an EV, however, according to several academic studies.
“A greater disease in electric vehicles can be attributed to a lack of previous experience, as a driver and as a passenger, where the brain lacks precision in the estimation of movement forces, because it is based on previous experience in other types of cars,” said William Emond, a doctoral student who is looking for the car disease.
Although electric vehicles are becoming more and more popular, combustion cars are still dominating. The runners have a longer story with gas cars and therefore had more time to adapt to their specific indices. If a person has spent most of their life driving a combustion engine car, their brain forecasts the acceleration after the engine reverend, a warning that he is about to undergo a change of speed. In a car supplied by battery, the electric motor does not make such noises.
In addition to general ignorance, research has found links between specific characteristics common to electric vehicles and transport evil. A 2024 Study concluded that there were strong correlations between the severity of evil of evil 2020 study have found that the lack of engine sound in an electric vehicle could be a major factor contributing to the increase in feelings of malasy.
“If we are used to traveling in non-EVS, we are used to understanding the movement of the car according to signals such as engine diets, engine vibrations, torque, etc. However, traveling in an EV for the first time is a new brain movement environment, which needs adaptation, ”explains Emond.
In addition, the regenerative braking technology used in electric vehicles – where the engine converts the kinetic energy to slow down the car with electricity which is then stored in the battery – causes low frequency decelerationThis means that the vehicle slows down gradually and regularly, over a relatively longer period, rather than quickly or in rapid pulses. Such low -frequency deceleration tends to be associated with higher levels of transport evil.
A 2024 Study suggested that functionality acted as one of the main triggers of transport evil in electric vehicles. The authors of the study wrote: “Our results confirmed that higher levels of RB (regenerative braking) can induce MS (transport evil).”
It is believed that transport evil is caused by a gap between various sensory signals that the brain receives the movement of the body simultaneously. More specifically, this happens when the inner ear, which helps control balance, eyes and body send contradictory brain information.
“A better knowledge of self-movement allows us to anticipate movement forces, which is crucial for transport evil. However, when movement forces such as estimated or anticipated by the brain differ from what is really experienced, then the brain interprets this” neuronal shift “as a conflict situation,” said Emond. “If this conflict persists over time, it can exceed a threshold for triggering the autonomous reactions of the body such as the symptoms exposed to” transport evil “.”
Being able to anticipate the movement of a vehicle seems to be an integral part of the experience of transport evil, which is why people who drive a car do not tend to feel symptoms. They know what will happen.
The interaction between the anticipation of the movement and the experienced real movement can be the reason why electric vehicles are associated with a transport evil, because these vehicles provide fewer indices on future movements.
“When you discover a new movement environment, the brain must get used to it because there is no knowledge of the previous experience in such a context. This is, for example, why almost everyone falls ill in zero-gravity environments, ”says Emond.
While the EV property continues to increase, some researchers are already examining a solution for the specific type of car nausea. Several research items have suggested that transport evil in autonomous electric vehicles could be treated by Visual use signals, such as interactive screens and ambient lighting, or Vibratory indices To allow the brain of a passenger to anticipate movement changes, attenuating the feeling of plants at the back of an electric taxi.
