Riding an electric car is uncomfortable with motion sickness, why won't the oil car?

Users who are familiar with electric vehicles will be "captured" by the unique driving texture of the tram: pure linear power release, silky smoothness without any pauses, accelerator pedal (used to call it so, let's not say "electric gate") without delay, millisecond-level response with pedaling... To sum it up in 3 words, it is - too! Refreshing! Finish!

Riding an electric car is uncomfortable with motion sickness, why won't the oil car?

But driving is driving, and people who sit in cars, maybe they feel very differently from those who drive. There are not a few people who react to "feeling dizzy in an electric car, and even feeling motion sickness". And the people who hold this view, they usually ride in fuel vehicles, and they do not feel any discomfort.

Riding an electric car is uncomfortable with motion sickness, why won't the oil car?

What is the truth of this? Why do not any of the drivers of electric vehicles say "feel motion sickness", but the people who ride the car give frequent feedback? According to the majority of media or radio car programs, most people attribute this phenomenon to "the violent acceleration of the tram".

Tram passenger "motion sickness experiment" phase I

Throttle depth limit!

So is acceleration fierce the main culprit that causes passengers to "feel motion sickness"? Big Tiger You used his car to do a "rough demonstration experiment". The car currently in use by Dahuyou is a GAC Trumpchi GA5 PHEV sedan purchased in 2015 and has driven 110,000 kilometers.

This is not a pure electric, but an "extended-range tram". The battery has an effective capacity of 10 degrees and can travel 40 kilometers in "pure electric mode". Usually, in order to save money, Dahu You commutes to work, charging every day, except for occasionally burning gasoline on weekends, weekdays are mainly in "pure electric mode".

There are 2 neighbors in the Dahu Youzuo community who go to work just right on the road, so they will take them together every day to "travel with the same car". At the beginning, Dahuyou installed a "limiter" on the accelerator pedal of his car (and call it so, not to say "electric door"). Make sure that if you press the accelerator pedal down 2 cm, you will no longer be able to press down.

In this state, the 2 female neighbors never felt dizzy or any other discomfort. Because after the throttle limit, the power of the vehicle motor is limited to 31KW, so the acceleration is very soft, through the intersection comparison observation, it is found that the starting acceleration of this car at this time is not faster than other fuel vehicles (even if the accelerator is pressed to a depth of 2 cm, it is limited)

Tram passenger "motion sickness experiment" phase II

Shallow throttle limit + no limit!

In the "Phase II experiment", I set the limit depth of the accelerator pedal limiter at 3 cm, at which point the power of the car's motor was limited to 45KW, and the acceleration was already significantly faster than the vast majority of logarithmic fuel vehicles on the road (except for modified steel cannons, sports cars, and other "people with a full throttle starting fetish").

At this time, the sound of tire idling "scratching the ground" can be occasionally heard at the moment of sharp acceleration, and the obvious "push back feeling" can be felt at the moment of starting and about 2~3 seconds after starting. But even so, the passengers in the car still did not respond to "dizziness" or other discomfort, but only felt "nervous".

Finally, I removed the limiter on the accelerator pedal, the throttle can be pressed normally to the end, at this time the motor can exert the original 94KW power, so to speak: the Trumpchi GA5 PHEV at this time, even if there are muscular performance luxury cars such as Porsche Cayenne and Mercedes-Benz Big G parked next to it, I am not worthy.

Riding an electric car is uncomfortable with motion sickness, why won't the oil car?

However, miraculously, the passengers in the car still only felt stimulated and nervous, but no one expressed "discomfort" or "motion sickness". ——So it seems that the violent acceleration of electric vehicles is not the cause of passengers' "motion sickness"! So what exactly triggers passenger discomfort?

After the same car turns off the "single pedal"

There is no discomfort for the passengers

An accidental incident caught my attention: readers familiar with Dahuyu must know that I often do tire performance measurements at tire test sites, and one of the test cars is a Tesla Model S-70D. This Tesla was purchased in 2015 and is currently about 180,000 kilometers.

Riding an electric car is uncomfortable with motion sickness, why won't the oil car?

UNLIKE THE NEW TESLA, THIS 2015 OLD MODEL S, ITS SYSTEM CAN BE SET SEPARATELY "KINETIC ENERGY RECOVERY" (THE CURRENT NEW TESLA SYSTEM CAN NO LONGER BE SET, IT IS ALREADY MANDATORY "SINGLE PEDAL")! . And my habit of driving that Tesla test car has always been "turn off the single pedal" mode.

Riding an electric car is uncomfortable with motion sickness, why won't the oil car?

At first, I didn't pay much attention until one day my colleague on the car asked about the "single pedal" function, so I set it up to him and explained the principle of "single pedal". As a result, when I turned on the "single pedal" mode, in the subsequent driving, the 2 colleagues in the car said that "people are uncomfortable and dizzy"!

After the same car turns on the "single pedal"

Passengers collectively react to dizziness and discomfort

Everyone knows Tesla's ability to accelerate, but he has also walked with colleagues so many times before, and no one has ever reported discomfort, and even several times colleagues in the back row have slept comfortably. ——So I have to suspect that the "single pedal" function is the culprit that causes everyone's discomfort!

Riding an electric car is uncomfortable with motion sickness, why won't the oil car?

The "single pedal" function, that is, the kinetic energy recovery function of the motor, as long as the accelerator pedal is raised, the motor will enter the "violent deceleration" state (that is, "braking by the electromagnetic force of the motor", which is called "single pedal"). ——But the texture of this brake is indeed very different from the traditional mechanical brake.

Passenger feedback "trams are more prone to motion sickness"

Could it be energy recovery (single pedal)?

In the "single pedal" state, the braking force of the motor is proportional to the speed of the car, and the faster the speed, the more fierce the deceleration (on the contrary, the deceleration effect at low speed is not obvious). In other words, the motor braking in the "single pedal" state, the acceleration curve is a very weird parabola (traditional mechanical braking is a straight line)!

Riding an electric car is uncomfortable with motion sickness, why won't the oil car?

So at the moment, based on my own experience and "experiments", I can conclude that the cause of electric car passengers feeling "motion sickness" is most likely the energy recovery (single pedal) function of the tram! At present, I have observed that some models with weak energy recovery, basically passengers rarely react to discomfort. For models with strong energy recovery, this negative evaluation will be more. So what do you think about this matter?
