Fleet of self-driving trucks rumbles across Europe
8 April 2016 | 0
A caravan of about a dozen self-driving, semi-trailer trucks for the first time finished a trip across parts of Europe this week.
The autonomous truck challenge was organised by the Dutch Ministry of Infrastructure and the Environment and included rigs from six manufacturers, including Volvo, Daimler and Volkswagen subsidiary Scania. The convoy journeyed from manufacturing facilities in Belgium, Denmark, Germany and Sweden to the port of Rotterdam in the Netherlands.
A Scania semi-trailer traveled the longest distance – more than 2,000 miles and across four national borders. The network of authorities involved in the pilot project included federal governments, roadway authorities and consumer groups from six nations.
“Over the past six months, there has been intensive and multidisciplinary cooperation/teamwork to realize this new form of mobility,” the EU Truck Platooning Challenge said in a statement.
“Truck platooning is a form of innovative mobility with a wide range of benefits in the areas of safety, traffic flows and efficiency. Truck platooning also reduces fuel consumption and CO2 emissions,” the challenge organizers said.
Platooning is a method of lining up trucks in columns where they follow each other at close distances (about 30ft) as they drive at a constant speed.
The trucks are linked via Wi-Fi, which allows them to brake faster than a human driver could. The responsiveness of each truck within the platoon is estimated at 25 times faster than the average human reaction time of one second – saving critical time in case of emergency braking.
Platooning also saves gas by keeping each truck in the wind stream of the one ahead of it.
Autonomous semi-trailers would also likely reduce shipping expenses by cutting labour costs since platooning trucks could drive nonstop to their destinations while human drivers would need to to stop and sleep.
“There are tens of thousands of people being killed on European roads each year,” said Melanie Schultz van Haegen, Dutch minister of Infrastructure and the Environment. “At present, 90% of all accidents are caused by human failure. New technologies can help mitigate the results of our shortcomings. What’s more, a self-driving car will drive more economically, saving fuel, which is good for the environment and consumers. This is especially interesting for freight transportation. Tests show that trucks that drive very close to each other save between 5% and 15% on fuel.”
The technology consists of a sophisticated vehicle-to-vehicle (V2V) communications system call RoadLINK, which was developed by NXP. RoadLINK uses the wireless communications standard IEEE 802.11p combined with NXP radar technology enabling trucks in a platoon to securely exchange information in real time and automatically brake and accelerate in response to the lead truck.
The high speed of communication and responsiveness of the autonomous system allowed extremely tight distances and synchronous driving between the platooning DAF Trucks, the group said.
In the US, the first autonomous semi-trailer hit the road in Nevada for its first pilot test almost a year ago today. Daimler unveiled its 18-wheeler during a ceremony at the Hoover Dam.
The Freightliner Inspiration Truck, a concept truck, underwent extensive testing, Daimler said, before the Nevada Department of Motor Vehicles granted it a license to operate on public roads in the state. This past year, the truck was driven more than 10,000 miles during a test in Germany.
