Hyundai Motor company recently demonstrated level 3 autonomous truck driving technology by autonomously navigating a semi-trailer truck across a 40 km highway in South Korea.
The demonstration was conducted using Hyundai’s Xcient model truck, which has a maximum load capacity of 40 tons. This was semi-equipped with a Society of Automotive Engineers (SAE) standard Level 3 autonomous driving system, enabling it to steer, accelerate or decelerate, and manoeuver through traffic, all without human input. A human driver was on-board to take over manual control when required. During the demonstration, the vehicle changed lanes during the natural flow of traffic, detected lane changes made by vehicles in front of it, navigated through tunnels, and performed a complete halt or acceleration according to the road traffic.
Maik Ziegler, director of commercial vehicle R&D strategy group at Hyundai Motor company said, “This successful demonstration proves that innovative autonomous driving technology can be used to transform the trade logistics industry. At this stage, a human driver is still used to control the vehicle manually in certain situations, but I think we will achieve level 4 automation soon as we are constantly upgrading our technological capability.”
Sang-Sok Suh, head of strategy and planning group at Hyundai Glovis said, “Hyundai Glovis’ success in utilising self-driving trucks as part of its delivery service proves that the self-driving technology is being utilised in actual logistics transport and can lead to mutual development. The company will be a leader in adopting future mobility technology like autonomous driving for the trade logistics industry.”
Special equipment for the special task
The semi-trailer truck is approximately 3.5 times longer, 1.4 times wider, and 9.2 times heavier than the average compact sedan, when comparing to an empty truck’s weight. This requires an advanced and detailed autonomous navigation system. Accordingly, Hyundai Motor equipped sensors similar to the ones featured in autonomous sedans, and additional sensors optimised for heavy-duty trucks, like a hitch angle sensor and trailer rear radar sensor. The equipment list consisted of 10 different sensors, including 3 front and side-rear cameras, 2 frontal and rear radars, 3 Lidars in the front and sides, and a hitch angle sensor in the trailer coupler which computes the change in angle between the truck and trailer in real-time, allowing the truck to be safely stabilised upon sharp turns.
Driving the future autonomously
Autonomous trucks maximise efficiency by maintaining the most efficient speed and velocity, reducing fuel costs, which makes up about one-third of long-distance delivery costs and thereby lowering the vehicles’ carbon footprint. Hyundai is currently investing in truck platooning technology (multiple trucks travel in a convoy behind a lead vehicle) that will enable this process to continue with autonomous vehicles, which it plans to complete by 2020s.
Hyundai Motor is planning to undertake further autonomous navigation technology tests in future in a variety of areas like Busan and plans to concentrate on its enterprise development capabilities with the aim of early commercialisation of the technology.
