Successfully completed demonstration at Hwaseong City's test track and Gwacheon City's general roads

LG Electronics has succeeded in developing the first LTE mobile communication-based V2X (Vehicle to Everything) terminal in Korea and autonomous driving safety technology utilizing it.

LG Electronics recently successfully completed performance verification through a demonstration of its self-developed V2X safety technology at the Korea Transportation Safety Authority’s Automobile Safety Research Institute’s test track in Hwaseong, Gyeonggi-do, and on a public road in Gwacheon, Gyeonggi-do.

LTE V2X is a technology that establishes a safer and more convenient transportation environment by connecting vehicles and all entities—such as Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), and Vehicle-to-Pedestrian (V2P)—via high-speed LTE mobile communication.

Autonomous driving safety technology is broadly divided into ♦ADAS (Advanced Driver Assistance System) sensor methods and ♦V2X methods. Among them, the method in which the vehicle directly detects surrounding hazards through ADAS sensors such as cameras, radar, and lidar has limitations, including a short detection range and the inability to detect situations behind obstacles.

LG Electronics’ V2X safety technology, the first of its kind in Korea, can overcome the limitations of such ADAS sensors by utilizing LTE communication to exchange and respond to the location, direction, speed, and traffic information of surrounding vehicles in real time.

LG Electronics showcased its "Sudden Braking Warning" and "Construction Site Warning" technologies during this demonstration. The "Sudden Braking Warning" technology prevents the risk of collisions by sending a warning message via LTE V2V technology before a following vehicle reaches the minimum braking distance, when a preceding vehicle—unvisible due to adverse weather conditions or blind spots—suddenly decelerates in the driving lane or the lanes to the left or right.

When two vehicles equipped with this technology are driving on the road and the leading vehicle brakes suddenly, the information is transmitted in real time to the following vehicle along with a Level 1 warning. Even after the Level 1 warning, if the following vehicle does not apply the brakes and approaches to a safe distance, a warning is sounded again.

"Construction Site Warning Ahead" is an LTE V2I technology that transmits construction site information to approaching vehicles via road IT infrastructure, helping them avoid hazards ahead while driving. Drivers of vehicles entering within a certain distance of the construction site will receive a safety warning message to slow down or change lanes.

Accelerating LTE V2X commercialization and leading the 5G-based V2X field

The newly developed LTE V2X terminal supports the LTE V2X international standard defined by the 3GPP (3rd Generation Partnership Project, a global technical cooperation organization for mobile telecommunications standardization) in March of this year, offering excellent versatility. LG Electronics plans to further accelerate technology development for the commercialization of LTE V2X.

Based on this, we plan to lead the 5G-based V2X field, which is considered an essential technology for the development of next-generation connected cars as it is about 4 to 5 times faster than LTE and can reduce communication latency to one-tenth.

LG Electronics has been acting as the lead developer for mobile communication-based V2X technology standards selected by 3GPP since 2015, and is leading the industry by recording the number one global market share in the telematics sector, a vehicle communication module, for five consecutive years since 2013.

In addition, last October, it established a joint research institute with Qualcomm, a leading company in the mobile communications semiconductor field, to develop next-generation connected car solutions, including 5G-based V2X.

"The successful development of this V2X safety technology once again proves the technological prowess of LG Electronics, which has been leading the industry," said Yoon Yong-chul, Executive Vice President and Head of LG Electronics' Automotive Components Technology Center. "We will continue to introduce advanced next-generation connected car solutions so that LG Electronics can become a key partner for autonomous driving for major automakers."
