According to foreign media reports, Hyundai Motor Company copied the real world traffic conditions on the intelligent Expressway in Lizhou City, Gyeonggi Road, South Korea, and successfully carried out the company's first truck formation test. In this test, Hyundai Motor Company adopted two xcient trucks connected with trailers.

The freeway is often crowded with vehicles for autonomous driving research, so it is very similar to the actual freeway traffic situation. The test successfully demonstrated the following technologies of Hyundai: vehicle formation, other vehicle insertion / exit fleet, simultaneous emergency braking and V2V (vehicle to vehicle) communication technology. To ensure safety, the speed limit of such vehicles is 60km / h. The test is part of a project launched by the South Korean Ministry of land, infrastructure and transport (Molit). Molit has been committed to supporting the groundbreaking work of autonomous driving technology since 2018. Along with Hyundai, the national program also involves governments, businesses and academia. Vehicle formation can reduce air resistance, improve vehicle fuel efficiency and reduce emissions, which is an environmental protection technology. When the rear truck approaches the lead truck, formation mode is activated and formation operations begin. Once the formation mode is activated, the rear truck will keep a distance of 16.7 meters from the front truck, and fine tune in real time according to the acceleration and deceleration of the leading vehicle. The driver does not need to step on the accelerator or brake, which greatly reduces the fatigue on the road and improves the safety. In addition, the mode activates lane keeping technology to allow the driver's hand to move away from the steering wheel. With vehicle formation technology, you can also seamlessly manage the insertion or insertion of other vehicles between trucks. If a vehicle is suddenly inserted into the truck fleet, the rear truck will automatically extend its distance from the lead truck to at least 25 meters. If the leading truck suddenly stops in an emergency due to an accident, the technology can also slow down and stop the following truck. In the test, the two trucks were also equipped with V2V system, which showed how to share information in real time between fleet vehicles (to improve acceleration and deceleration control), and also combined with ADAS (advanced driving assistance system) information of various sensors (such as camera and radar). In addition, V2V technology is used to realize the real-time video sharing function. By displaying the video of the leading vehicle, the driver following behind can see the road ahead, which solves the problem of limited vision in front of the driver behind. Hyundai will strive to achieve a high level of vehicle formation technology, so that vehicles can work at a closer follow distance, and in the future to achieve traffic information that can optimize the journey. In August 2018, Hyundai Automobile and logistics company Hyundai glovis cooperated to complete the first self driving truck trip on a 40 km highway between Gyeonggi Yiwang city and Incheon city in South Korea. The truck has L3 self driving ability. The modern xcient truck weighs 40 tons and is sold all over the world. In addition, Hyundai is also leading environmental initiatives in the field of commercial vehicles, launching xcient trucks in September last year, and plans to deliver 1600 vehicles to Switzerland by 2025.
