Ssangyong Motor has expanded the function of smart key to smartphone and developed technology to overcome the shortcomings of smart key. Unlike ordinary smart keys, it is differentiated from economical and convenience.

If you do not accidentally take your smart key at home, or wear a simple outfit for athletics, it's basically a smart phone to replace the existing functions such as entering and starting the car.

The existing smart key has no screen and it is difficult to check the status information of the vehicle. Some smart-key industry has applied display liquid crystal to smart key to overcome this disadvantage, but it is not popularized because of high price, product size, battery discharge amount.

Ssangyong Motor is developing a smartphone-based smart key that displays real-time status of the vehicle through the display of the phone. This technology is based on Bluetooth Low Energy (BLE) communication, which is different from simple smart phone interfacing function using the connected mobile communication network.

The connected car service is a structure that utilizes the mobile communication network, paying the monthly communication monthly fee. It does most of the remote functions without distance restrictions, but car key (smart key) authentication must be done to start the car. On the other hand, Ssangyong Motor is developing the smartphone car key using the BLE communication technology for the first time in the industry. Because of this, there is no need to pay a monthly fee, and remote functions are limited to short distances, but they are convenient in many ways.

Because it uses a smart phone, it implements functions such as car start and door opening without separate smart key authentication. In addition, when the battery of the smartphone is discharged, all functions can be used only by touching a specific part of the vehicle using short range wireless communication (NFC) communication.

There are no cases of mass production of smart key systems using BLE communication. In the case of BLE communication-based smart keys, it is difficult to develop precise technology that can grasp more precise positions than existing radio frequency (RF) or low-frequency (LF) based smart keys.

Another problem with smart key development is security problem solving. There is a risk of hacking by application of BLE communication. When Ssangyong approached the vehicle near the vehicle, Ssangyong Motor adopted a separate security algorithm for the smart key, BLE module, and authentication controller, so that it was recognized only for the authenticated smart key (mobile phone).

A related person of Ssangyong Motor said, "In order to develop future smart key using BLE communication, we are trying to secure BLE positioning technology and security." At the completion of the development, the driver will not only operate the vehicle but also acquire vehicle information It will be possible. "

Opening and starting wi… Busy commuting, driver A does not take his car keys when he leaves the house. When you put your smartphone on the handle of the vehicle, the door opens with the sound of 'pivic'. Putting your smartphone on the driver's seat wireless charger pad and pressing the 'Start' button will start the car. It is not a story of the future. Hyundai Mobis plans to develop 'NFC Smart Key' using proximity wireless communication (NFC) technology and mass-produce it in 2019. Proximity wireless communication is a technology capable of bi-directional data transmission / reception between terminals within a distance of 10 cm. Hyundai Mobis has developed an NFC smart key that can be used as a smart key for a car by installing an app on a smart phone that supports proximity wireless communication technology. Hyundai Mobis is the only company in Korea to complete the development of this technology. Only a handful of companies have acquired relevant technology worldwide. In the IT field, it is widely used for electronic payment and financial transactions such as traffic card, credit card, membership card, etc. However, there are few cases of application of technology in the field of automobiles.

What should I do when I need to use my car with someone else? An NFC smart key can give a vehicle owner a key authorization to a third party, such as a spouse. If you need permission, you can install the app on your smartphone and go through the verification process. At this time, the owner may give up only a part of the authority and prevent the risk of accident caused by unreasonable use of the vehicle. For example, a third party could have the car write at a certain time, or the door might open but not start. Hyundai Mobis developed a 'certified controller' that uses data encryption technology and authentication technology in preparation for the risk that the smart key will be hacked and the car stolen. Highly encrypted car and smartphone information prevents hacking programs from reading information and accurately verifies whether the car and smartphone owner match up. For more complete security, MOBIS plans to verify security threats even after product launches. http://biz.khan.co.kr/khan_art_view.html?artid=201803281642001&code=920508#csidx2b3b3337f0ad73bae4e0d2b58e82346

A car that can be used to open and open the car door without a key using a phone is being developed, the Wall Street Journal (WSJ) reported Wednesday. The rugged keychain or electronic key needed to open the car door and start it is now in the same position as the cassette to enter the list of antiques to be found in car history books. Several major auto parts suppliers have developed a system that can connect to a smart phone and open the door without a key. Car manufacturers also offer mobile apps that allow drivers to open or start the car remotely, but now the electronic key must be in the car before the car can move. However, if you lose your electronic key, it will be cumbersome and expensive to replace. Denso Corp., a Japanese auto parts company, announced today that it has acquired InfiniteKey Inc., a US-based software startup with patented technology that allows smartphones to open doors without a key. This key-free technology can quickly spread through Denso's extensive supply network. "Vehicles with Denso's new technology will be available to dealers in 2019," said Bill Foy, senior vice president of Denso's US operations. Hotels and other businesses are also researching smartphone apps that replace traditional keys. Keyless cars are the latest in a series of innovations that make old standard car parts obsolete, from wire antennas to dangling fuel tank caps. Manufacturers of these components also need to keep pace with this new technology. Vehicle antennas with sophisticated wireless connectivity do not appear hidden in roof mounted 'shark fins', and in newer models cars do not have caps on fuel tanks. Parts maker Martinrea International Inc., who contributed to the market with a cap-less fuel filler 10 years ago, says that 30 percent of cars sold in North America are equipped with screw cap tanks. In addition, cigarette lighters, compact disc players and spare tires are just some of the things that will remain in the foreseeable future. The keys to the car made of metal gave way to a thick electronic key or push-button, and now it's time for them to disappear. http://www.econovill.com/news/articleView.html?idxno=328505
The biggest rival in the smartphone market Samsung and Apple are expected to use the same kind of 'digital key'. Two companies are participating in a technology development consortium that can use smart phones like car keys. According to industry sources, the Car Connectivity Consortium (CCC) group, which Samsung and Apple are part of, will launch a 'Digital Key 1.0' system that can use smartphones as a car key, (Local time). According to CCC, digital key 1.0 allows you to open, lock and start your car through the smartphone app. Because it uses Near Field Communication (NFC) technology, it can be used even a few steps away from the car. In addition, other settings allow you to have access to your car even with someone else's smartphone. This technology is expected to be used in emergencies, ballet parking and car sharing industry. "The digital key we provide is very popular with a lot of people," said Maffir Rahman, CCC group president. Leading global innovation for smartphone-based automotive connectivity solutions, the CCC Group is an organization in Oregon, USA that focuses on developing systems such as 'digital keys' using smartphones to help people get more comfortable with their cars. . CCC is also known as MirrorLink ™, a solution that links bi-directional links between smartphones and in-car displays. Rahman said he has "the best security system" for Digital Key 1.0, and showed strong confidence in the security issues people might be worried about. "We used the same NFC chips used in our existing Android and iOS smartphones and based on TSM (Trusted Service Manager), so we have thorough security from start to finish even when connected to mobile apps," he said. The digital key service can be used for all vehicles belonging to the CCC group such as Hyundai Motor, Audi and BMW. Volvo cars have also been applied for, but have not been commercialized yet. The CCC group has already begun developing the next step, 'Digital Key 2.0'. The market launch date is scheduled for the first quarter of 2019. Rahman said, "Digital Key 1.0 already boasts a strong influence in the market." Digital Key 2.0 is expected to have even greater impact.

When the driver puts the smartphone on the handle of the car door, the near-field wireless communication (NFC) receiver mounted inside the door recognizes the signal of the smartphone and opens the door. After sitting on the driver's seat, put the smart phone on the car stand, press the start button, the wireless charging starts and the car and the smartphone are connected with Bluetooth. As NFC technology is applied to car keys, driving habits are changing rapidly. According to the industry on November 11, NFC technology, which was developed in 2002 and used mainly for transportation cards and credit card payments, has been expanded to car keys, and smart phones are turning into car keys. NFC is a kind of electronic tag (RFID) that transmits and receives bidirectional data by bringing two or more terminals close to each other. In the second half of last year, Mercedes-Benz E-Class was the first to adopt the first type of digital key using NFC. Hyundai Mobis participated in the Consumer Electronics Show (CES) held in Las Vegas in January and introduced the NFC-enabled digital key system. When NFC technology is applied to a car key, the driver automatically adjusts the seat according to the driver's body type, and the smartphone screen cooperates with the display of the car to reproduce the usual favorite music according to the driver's voice command. When you turn off the car, you can see the status of the car, the driving record, and the parking position, etc. The proliferation of car digital keys has a side to prepare for the expansion of 'car sharing' service, which will be coming soon. If autonomous vehicles become commonplace, autonomous vehicles can be obtained in a short time through smartphone applications, and it is more convenient to share the car than to own it. It is an analysis that digital key using smart phone will be utilized for such car sharing. In some cases, there is a concern that smartphones can become targets of hackers if they replace their car keys. However, it is safe to apply advanced encryption techniques used in financial settlement to automobile digital keys http://www.hankookilbo.com/News/Read/201809101443388972
