The car uses a mobile phone and internet chip is panicked

In China. Furthermore, a vast debate has opened on a subject concerning security and technology of cars. However, It all started after the launch of the new Xiaomi Yu7. Similarly, which uses a chip designed for smartphones (a “general public” chip) to manage the dashboard and infotainment system.

This choice arouses many discussions because this chip is not designed to withstand the difficult conditions that a car can face. However, such as heat, cold, vibrations and shocks. And above all, it is not designed according to the same safety standards required for use in vehicles.

One of the leaders of Audi in China. Li Fengang, wanted to express his point of view by publishing a video where he explained why the use of “general public” fleas in cars can be risky and clearly said:

“Cars are not smartphones. There are no experiences car uses mobile phone internet on motorists.”

But what are, in practice, the differences between “general public” fleas and “automotive” those?

The main differences – Car uses mobile phone internet

As we can read on NewsCarChinaLi explained that there are three major fundamental differences between consumer chips. those intended for the automotive industry:

The consumer electronic devices generally operate in stable interior environments, while vehicles face extreme conditions such as high temperatures, intense cold, rain, snow, dust, shocks and vibrations.

Automotive chips are designed to operate reliably from -40 ° F to 302 ° F (-40 ° C at 150 ° C). while the general public fleas are designed for a much more limited beach, from 32 ° F to 158 ° F (0 ° C at 70 ° C). In addition, car materials must be resistant to high temperatures, corrosion and condensation.

The consumer electronics have a rapid renewal cycle, with chips designed to typically last car uses mobile phone internet 3 to 5 years. Cars, on the other hand, are designed to last 10 to 15 years or over.

The car fleas require suppliers that they guarantee stable supply for more than 10 years. with very high coherence between the different production batches, requiring Multi-Lots validation.

Unlike smartphones, vehicles carry passengers at high speed, and a failure of the components can have fatal consequences.

The general public fleas allow a defect rate of up to 500 ppm (parties per million). or 500 failures for a million units. Highlights, on the other hand, generally require a defect rate of less than 1 ppm (one out of one million).

Is the car that uses phones for phones?

When Tesla, a few years ago, experienced the general public fleas in her vehicles, she underwent reminders for overheating. Today, however, things seem to be different. As the Chinese press reports. Professor car uses mobile phone internet Zhu Xichan, an expert in automotive engineering, explained that modern cars contain around 1,000 fleas, but only those related to security must pass rigorous tests (such as AEC-Q100 and ISO 26262) to be considered as “automotive quality”.

Others, less critical, can also use consumer chips, provided they pass certain environmental tests.

In the case of the YU7. the Snapdragon 8 Gen 3 is a chip too recent for having already obtained all the automobile certifications, which suggests that it has been used without specific specific certification for vehicles.

Xiaomi. however, said that the entire module on which the chip has passed the AEC-Q104 test, a system certification which checks the resistance and stability of all components over time. This does not guarantee that the chip is “automotive quality”. but shows that an effort has been made to adapt it to use car uses mobile phone internet in cars.
