Hyundai & KT Test 5G C-V2X Tech

Hyundai Mobis held the “Technical Cooperation Result Demonstration” together with KT and Hyundai MnSOFT at the Hyundai Mobis Proving Ground in Seosan, Chungcheongnam-do to share the results of joint development of the 5G connected car technology, and discuss future collaboration projects. The above autonomous driving situation is part of the scenario that was actually demonstrated at this meeting.

Hyundai Mobis and KT, which have been cooperating closely with each other since they formed a technical alliance for connected cars last year, successfully completed the first cooperative development projects.

The two companies entered into an MOU for jointly developing the ‘5G-based connected car technology’ last August, and KT built the 5G infrastructure for technology development at the Hyundai Mobis Seosan Proving Ground by the end of last year. Hyundai Mobis began to work in earnest with Hyundai MnSOFT on the first project in January, i.e. development of the real-time navigation update technology and the mobile communication-based Cellular Vehicle to X (C-V2X) technology, and has since been endeavoring to secure related technologies.

Hyundai Mobis developed the technology for collecting traffic information through the sensors of the autonomous driving test vehicle M.Billy, and extracting core information that affects driving and transmitting it to the server. KT supported the connection between the 5G terminals installed in M.Billy and 5G communication base stations, and Hyundai MnSOFT modified and updated the map based on the received information in real-time.

The real-time navigation update technology reflects the traffic information, which preceding vehicles collect and send to the server, in the map in real-time and delivers it to following vehicles. The C-V2X technology uses the mobile communication network to share vast amounts of data with vehicles, infrastructure, other cars and pedestrians in real-time, and thus enhances the safety of autonomous driving. They are essential technologies for securing safety in the age of fully autonomous driving in which the system takes the initiative completely.

Hyundai Mobis and KT used these two technologies to demonstrate 5 scenarios, i.e. real-time precise map update, avoiding construction sections, preventing collision in case the vehicle, which is two cars ahead, makes a sudden stop, emergency situation 5G video streaming and perceiving pedestrians. These scenarios are representative cases of the connected car technology, proposed by the Society of Automotive Engineers (SAE) of the US, which match the levels of technology with global standards.

“Through synergy with KT which has the world-best 5G communication technology, we were able to secure a high level of technology in a short period of time,” said Chang Jae-ho, Senior Vice President and Head of Electrical and Electronics R&D Division of Hyundai Mobis. “We will enhance the reliability of connected car technology and realize the age of safe future cars without the risk of accidents by further reinforcing the cooperation between the two companies.”

“While developing this technology with Hyundai Mobis as an R&D partner, we could verify the competitiveness of its autonomous driving sensor and control technology once again,” said Jeong Yoon-sik, Executive Vice President of KT Enterprise Customer Business Unit. “We will lead the coming age of future cars by expanding our collaboration, including providing contents for autonomous vehicles to the entire connected car ecosystem.”

[Situation #1]
Two M.Billys, Hyundai Mobis’ autonomous driving test vehicle, start autonomous driving one after the other. The information, which the preceding vehicle secured through autonomous driving sensors, e.g. cameras and radars, is reflected on the map in real-time, and delivered to the following vehicle. As the preceding vehicle turns into a side road, comes across a construction zone and stops, the M.Billy, which was just tens of meters behind, uses this information to modify the best route in real-time and takes a detour.

[Situation #2]
Another vehicle is added, and three M.Billys are driving on the road this time. When the M.Billy in front finds a bicycle that suddenly appears and proceeds to make a sudden stop, the car right behind perceives the situation with its sensors and makes a sudden stop as well. The M.Billy following the second M.Billy does not perceive the sudden stop of the first vehicle with its sensors, but receives this information through the network and immediately changes lanes and avoids collision. Also, the situation that made the vehicle in front suddenly stop is shown in real-time video streaming through the 5G communication network.
