The Hyundai automaker presented a new technology for unmanned control of the column truck
Hyundai Motor Company successfully spent the first in the history of the company’s cargo trucks at the Smart Highway of Yuzhu (YEOJU) in the symotic setting of the real road. The demonstration has passed with the participation of the two main tractors of XCIENT with trailers.
The «smart» Highway is 7.7 km by a length of 7.7 km, established by the Korean government to develop unmanned driving systems. The highway where cars are constantly driving, imitating the conditions of the real high-speed highway, is used to develop unmanned driving technologies.
Hyundaimotor successfully demonstrated the following features: the coordinated movement of trucks, between which other cars are periodically embedded, simultaneous braking, as well as data exchange between vehicles (V2V). For safety reasons, the speed did not exceed 60 km / h.
With a coordinated movement of the autocolone behind the head car, a smaller resistance of the air is created, which allows to reduce fuel consumption and harmful emissions and in general increase the environmental friendliness of transport traffic.
The formation of the autocolone occurs when the driver of the second truck is approaching the head and includes coordination mode. When activating the auto-roll mode, the slave truck is withstanding the distance of 16.7 m and adjusts to accelerate and braking the head car. The driver does not need to use accelerator pedals and brakes, which seriously reduces fatigue on the road and increases traffic safety.
In this mode, the retention system is also activated in the movement strip, allowing the driver of the truck does not keep his hands on the steering wheel.
In autocolon mode, trucks are coping with situations without problems when other cars are interconnected inside the columns. If the car is embedded in front of a truck in the column, he automatically increases the distance to at least 25 m.
When a head truck for any reason suddenly stops, the system will slow down and stops the slave truck.
In this experiment, the V2V system was installed on both trucks, which allowed them in real time to exchange various data, including data from the camera and radar of the driver assistance (ADAS), which contributed to more efficient control over acceleration and braking.
In addition, the V2V system made it possible to implement the function of the general front view in real time. It transmits the video from the head car to the driver of the slave truck, which receives a great road overview ahead.
