Since Tesla Model S has opened his head with a 17-inch central control, the car manufacturers opened a big The non-resting climb of the sized control screen is to show its technical strength.
Honda E
such as Honda The first electric car Honda E, equipped with two 12-inch entertainment screens, across the width of the entire dashboard. 
Ford just listed electric SUV Mach-E screen size has also reached 15.5 inches.
Of course, these are not the most exaggerated, Cadillac will be listed next year’s Lyriq SUV allegedly equipped with a 33-inch curved surface. Big screen.
Mercedes-Benz hyperscreen, size is 56 inch
The inventor of the car Mercedes-Benz announced this year CES will announce the flagship electric The super giant screen with the car EQS, this huge surface screen system is named Hyperscreen, which is more exaggerated than the 48-inch big screen of the start-up company. The width of the entire screen has even reached 56 inches. .
The screen becomes bigger. It is a lot of benefits in manufacturers and consumers, but not only more technological luxury, and more functions that can carry in the vehicle system. Of course, it is also more convenient to read and use these functions.
However, it seems that the manufacturer has an important issue when adding more functions and increasing sizes to the touch screen, and the greater the more touch screen. The attention of the driver, this is exactly that safety experts and legislators are notI often worry.
The British Transportation Research Lab TRL (predecessor for traffic research laboratories) did once in 2020, revealing these central control large screens to make the driver distracted.
Apple Carplay
The operation function of Apple Carplay and Android AUTO significantly increased the driver to respond to emergency events. In response time, the driver is more than the response time of sending SMS or driving under alcohol and cannabis.
The results of the study allow TRL
behavior
scientific person in charge, the organizer of the study NEALE KINNEARAR Open eye.
He is expected to have a significant distraction in the driver, but the driver has exceeded his expectations on some incidents from the road from the road.
“I am surprised about this level of reaction. For example, the driver takes 20 seconds in the SPOTIFY to select music tracks. In the real world, you can’t Imagine how this is affecting traffic safety, “he expressed.
As for the current popular speech control, don’t think it will not distract. TRL’s research data shows that while using voice control, although it is less than using the touch screen, it is still much more than the reaction time of the dangerous response time compared to the driving of a SMS or drunk driving.
Because of the technical concerns,The car itself is becoming more secure, and the DFT considers whether the information entertainment system will be the culprit. It wrote in the comments: “The progress of the automobile information entertainment system and mobile phone technology means that the driver may be more and more factors.”

In the cabin of the car, the touch screen is a normalization configuration of the current mainstream technology has become a vehicle.
IHS Markit is shown that 82 percentage in the United States 2019 has a smart touch screen, and this proportion is 53% before 5 years ago.
The design of the touch large screen interface is clearly related to the driver distract. TRL uses Apple Carplay and Android AUTO mobile phone mirror screen in the in-vehicle system, because their interfaces and operations are the same for all cars that provide these features, while car manufacturers use their own design. There are many ways to interface.
MG ZS electric version 8-inch touch screen
BMW new 3-strand cockpit performance [123
Foreign media What Car has also tested some mainstream vehicle information entertainment systems. Rank 20th is the 8.0-inch touch screen of MG ZS electric version, which is all central control. The BMW 3rd part of the BMW smart interconnected cockpit is the best in the test.
The physical buttons are still the most practical, the safest
The conclusion that the TRL test is obtained is that one item is executed. On the time used by the operation task, the performance of all touch screens is poor than the physical buttons.
For example, adjusting hot wind control on a touch screen or a physical switch may take twice or more, andScaling or finding a broadcast station on a sailing station may take eight times or more.
Therefore, the safety hazard caused by the middle control screen is not small, and the two-way combination of legislation and technology may be required to solve the problem.
First, in technology, automatic emergency braking has made more and more distracted drivers have little trouble (if it is not a life), and the lane assist system can Make sure the driver and their cars are driving in their own lanes.
Secondly, in terms of legislation, the EU first starts actions, considering the new car to force the driver with an eye tracking instrument. The monitoring system will warn the driver, if their sight is removed from the previous road too long.
With the application of automatic driving technology, driver monitoring may be more important, and it can also remind drivers to see how long they look at the screen. Because the study of TRL found that the driver greatly underestimates the time of the road to leave the road when the screen function is operated.
In view of the increasing role of the central control in the vehicle, the government and industry regulatory agencies should also establish a test standard similar to NCAP as soon as possible to assess each new car. The manifestation of the medium control screen in the attention of the driver. 
Tesla’s large screen leads the wind circle
Further, it is worth mentioning that the central control large screen itself Product quality should also establish a clear standard.
It is specifically that the central control screen cannot be used normally because the vehicle’s embedded multimedia memory card (EMMC) failure causes the central control screen.
According to Tesla, its memory card itself has 3000 program / erase cycles, but over time, EMMC hardware will exhaust life cycle of each memory cell. .
When the EMMC storage unit hardware reaches the life limit, the EMMC controller will not maintain the integrity of the file system, which in turn leads to a failure of the central display software function, indirectly leads to reversing images. A series of systems such as defrost / remove control and external steering lamps.
In summary, the car manufacturer is transferring more control over automobile auxiliary equipment due to no standard or constraints. To the touch screen in the instrumentation platform, this kind of practice is safe and reasonable.
, no matter whether domestic or abroad, regulatory measures for information entertainment systems are still very small, in order to Reduce the hidden dangers that it brings, and the medium control screen is necessary to become the focus of new regulations.
