Semi-autonomous cars are expected to hit the roads in Europe next year with truck convoys following a few years later. But before different brands can share the roads, vehicle manufacturers need to agree on standards for automated functions.<\/strong><\/h3>\n
\n
\n
\n

Automation will increasingly allow vehicles to take over certain aspects of driving. However automated functions are still being fine-tuned, for example, to ensure smooth transitions when switching between the human driver and driverless mode.<\/p>\n

Standards also need to be set across different car manufacturers, which is one of the goals of a project called\u00a0L3Pilot<\/a><\/u>. Although each brand can maintain some unique features, automated functions that help with navigating traffic jams, parking and motorway and urban driving must be programmed to do the same thing.<\/p>\n

\u2018It\u2019s like if you rent a car today, your expectation is that it has a gear shift, it has pedals, it has a steering wheel and so on,\u2019 said project coordinator Aria Etemad from Volkswagen Group Research in Wolfsburg, Germany. \u2018The approaches and the interfaces to the human driver are the same.\u2019<\/p>\n

To get the same functions from different brands to operate in an identical way, the team is creating a code of practice. This will result in a checklist for developers to run through when creating a self-driving function. \u2018It\u2019s like a cookbook for how to design and develop automated driving functions,\u2019 said Etemad.<\/p>\n

So far, the project team, which includes representatives from 13 vehicle manufacturers, has been conducting initial tests to make sure their company\u2019s technology works. Cars are equipped with several sensors as well as cameras and computers which need to be properly calibrated to deal with real-world traffic.<\/p>\n

The next step is to test the automated functions on public roads to ensure that the vehicles are ready. The tests will begin this month. Volunteer drivers will be chosen from diverse backgrounds, including different ages and genders. \u2018We plan, all in all, to have 1,000 drivers using 100 vehicles in 10 different countries,\u2019 Etemad said.<\/p>\n

Transition<\/strong><\/p>\n

The technologies being trialled will cover a wide range of situations from\u00a0overtaking on motorways to driving through urban intersections. Long journeys are also planned to see how people are able to transition back to driving after a long time in automated driving mode.<\/p>\n

\u2018We really want to understand if the way we have designed our systems is the way drivers expect them to behave,\u2019 said Etemad.<\/p>\n

The team will also be investigating other aspects of automated driving such as the effect on traffic flow and CO2 emissions. Self-driving features are likely to make driving more efficient due to connectivity between vehicles and infrastructure, for example, although research so far has shown mixed results due to other contributing factors such as more people choosing to drive.<\/p>\n

The first automated functions, which should be available in the next year, are likely to be for motorway driving, according to Etemad. Parking functions are likely to come to market next followed by automated urban driving, which is much more complex due to additional elements such as pedestrians and cyclists moving around.<\/p>\n

\u2018There will be a good contribution from the project with results about long-term automated driving and a general understanding of people and functions that will impact how these systems are developed,\u2019 said Etemad.<\/p>\n

Automated functions are of interest for trucks too, where networked vehicles driving in a convoy could help save fuel, cut down on driving time or help with traffic flow. Truck platooning involves several trucks linking up through a wireless connection when they are close by so that they can share information and use automated functions to drive together as one. But so far, the concept has\u00a0mostly been demonstrated in trucks of the same brand and in very few cases, with\u00a0two brands<\/a>.<\/p>\n

\u2018Each automotive manufacturer tries it out and develops the technique within their own factory,\u2019 said Dr Marika Hoedemaeker, a senior project manager at the Netherlands Organisation for Applied Scientific Research (TNO) in Helmond.<\/p>\n

\n

\u2018It’s not only communicating with the platoon (of networked trucks) but also with the outside world.\u2019<\/p>\n

Marika Hoedemaeker, senior project manager, Netherlands Organisation for Applied Scientific Research<\/p>\n<\/blockquote>\n<\/div>\n

Truck platooning<\/strong><\/p>\n

Hoedemaeker and her project partners are now trying to break new ground by developing truck platooning that works across different brands as part of a project called\u00a0ENSEMBLE<\/a>. \u2018Now we\u2019re going to show that we can do this together with all the European truck manufacturers,\u2019 said Dr Hoedemaeker.<\/p>\n

The first phase, which the team has just completed, involved coming up with specifications that need to be implemented by all manufacturers. For example, braking and speed keeping will be automated whereas steering won\u2019t be.<\/p>\n

They\u2019ve also come up with guidelines for how a convoy will respond when it enters a zone with a new speed limit or passes a toll gate, for example. \u2018It’s not only communicating with the platoon but also with the outside world,\u2019 she said.<\/p>\n

The team is also keen to gauge the impact that a platoon will have on traffic. They would like to calculate its effect on traffic flow and whether it would in fact reduce congestion on the roads. Driving simulators will also be used to see how other drivers react when they encounter an automated truck convoy.\u00a0 \u2018Will it change their traffic behaviour or will they never drive in the right lane anymore? There are lots of questions around this other traffic behaviour as well,\u2019 said Dr Hoedemaeker.<\/p>\n

Once specifications have been implemented in the trucks, they will start to test platoons on dedicated grounds then on public roads. Since trucks cross borders quite often, they will have to respect laws in different countries which vary across EU member states. The minimum following distance between vehicles, for example, differs from country to country.<\/p>\n

In a final showcase event in May 2021, trucks from seven different brands, such as Daimler and Volvo, will drive together in one or more convoys across national borders, most likely to a key goods transport destination such as a large European port.<\/p>\n

Following this deployment on European roads, Hoedemaeker expects the first generation platooning trucks to start being manufactured and sold a year after the project ends in 2021.<\/p>\n

Since platoons are being developed worldwide, the standards created during the project could also be adopted more widely.<\/p>\n

\u2018I think there is potential that the rest of the world could say they (Europe) already thought about the standards so we can use these and not do the whole thing over again,\u2019 she said.<\/p>\n
