NFC TREND

- Sep 27, 2018-

After the car became the most important market segment in the electronics industry, many technologies were slowly ported to the car. Who will be next?

When chatting with friends in the electronics industry, the car cloud can often hear this argument: "The industry is getting thinner, that is, the car has saved us." And whether the electronics industry is really thin, but the car, indeed It has become a very important market segment for them. Many companies are working hard to find the second spring of the housekeeping skills in the automotive industry.

For example, HUD (head-up display), although HUD is not popular in the car, it is only available on some high-end models, but in many conceptual technologies and concept cars, the existence of HUD is already a habit. . So, what is the next technology that will be ported to the car?

A recent article by the American Society of Engineers (SAE) argues that NFC technology will be the next technology to be ported from the mobile end to the car.

NFC technology is a technology? NFC is similar to Bluetooth, except that the communication distance is much shorter than Bluetooth. The full name of English is Near Field Communication, so the scientific name is called short-range wireless communication, allowing non-contact between different electronic devices. Point-to-point data transmission, the effective distance is only about 10 cm. Now NFC technology is used on the bus card and some mobile phones to support the app.

Although the transmission distance is extremely short, the biggest advantage of NFC is that the interaction process is very simple. The same is the connection between the mobile phone and the car. If you use Bluetooth, you should open the Bluetooth of the phone and the car from the settings, and then search for the specified device for pairing. As long as NFC puts the phone close to the NFC chip position of the car and enters the effective distance, the connection screen will appear on the mobile phone. All you have to do is tap the page. After the connection is established, media files such as music videos can be transmitted, and the path set on the mobile navigation app can also be transmitted to the vehicle.

Another application scenario for NFC in the car is the car key. NFC's energy consumption is so low that it can be implanted in the car key to unlock the door. Extending further, you can also store some personalized settings in the device, such as seat position, favorite music and radio programs, etc., can also be used for identity verification, reading vehicle information and so on.

Another solution is to turn NFC-enabled mobile phones into car keys. NFC is a good solution for scenarios that require flexibility, such as car sharing, car rental and fleet management.

So, is the NFC era coming?

The earliest link between NFC and the car was actually pushed back four years ago when Nokia joined hands with the mobile phone manufacturer and car manufacturer to establish the Car Connectivity Consortium (CCC). At that time, one of the goals of the CCC was to be able to develop universal standards and promote the application of NFC in automobiles. If most people are not familiar with the name CCC, then MirrorLink should have heard about it. This is one of the achievements of CCC.

In four years, MirrorLink was carried forward, and NFC did not achieve the same result. One of the most important reasons is that the support of hardware products has not kept up. Unlike consumer electronics, cars have a much harsher working environment. Being able to adapt to such a work environment is one of the thresholds. The second threshold is that such a goal must be achieved at an acceptable cost.

And let SAE conclude that this year, several semiconductor manufacturers have successively introduced NFC chips specifically for use in automobiles. These chips can meet the requirements of the car in terms of cost, power consumption and development time. Popular demand.

Broadcom released an NFC chip BCM89095 at the beginning of last month. Compared with the previous Bluetooth chip, the energy consumption of the NFC chip is reduced by 60%, the number of components used is reduced by 30%, and the chip size is reduced by 35%. -40 ° C ~ 85 ° C working environment. The BCM89095 has a transmission speed of around 100kb/s and supports the latest NFC specifications.

NXP released NFC solutions for cars at earlier CES, including the NCF29A1 and NCF3340. The NCF29A1 integrates Passive Keyless Entry (PKE) and RF transmitters to enable remote control of the vehicle and as one of the anti-theft methods. The NCF3340 is the industry's first NFC-based control interface for use in automobiles. The NFC controller can interoperate with other NFC components, saving manufacturers' development time and enabling car companies to promote NFC applications to the market faster.

Hallexis is also developing related NFC devices for PKE and working with Freescale to develop wireless charging; analog integrated circuit and sensor manufacturer AG released an NFC development tool last fall. There are software interfaces for Android, Linux, Win7/win8 and other operating systems, so that the application environment of NFC technology has been moved outside the mobile phone.

Hyundai, one of the founding members of CCC, announced at the end of 2012 that it is working with partner Broadcom to replace the car keys with smartphones in 2015, using NFC technology to unlock the doors, start the engine, and be able to The content is mapped to the car.

All the news came from good news, but it can't be said that the NFC era is coming. It can only be said that the era of NFC in the car has begun. After the technical and cost issues are resolved, there are still security issues to be resolved. Smartphones can be described as the current information leaks. Is this unlocking method easy to crack? What should I do if the phone is lost? Vendors must give consumers a reassurance before they can be implemented.
