Video: this is what it looks like when a truck is threaded autonomously

According to the institute’s announcement, it is above all complex traffic situations during the onboarding and overtaking processes that require a high level of attention from the driver. In this context, lack of concentration easily leads to accidents, automated assistance while driving counteracts this. On a test track in Sweden, the Fraunhofer Institute has now demonstrated, together with partners such as truck manufacturer Scania, what it looks like when a truck changes lanes independently and does not ignore traffic.

Autonomous threading is a very complex process

The step that has been taken now is important for the autonomous driving of the future. Because vehicles are already taking individual steps while driving alone. For example, when parking, but also when accelerating and braking independently in traffic jams or moving traffic. Now, for the first time, it has been possible to demonstrate the process of threading a truck between two cars that circulate alongside it, in a fully automated way. This should be emphasized because many systems and sensors must work together to successfully complete the threading process.

As part of the test that has already been completed, not only radars and cameras were used in the vehicle, but also satellite signals and other navigation solutions. Complemented with reference stations along the route, participating companies also rely on a combined GNSS / sensor (GNSS: Global Navigation Satellite System) solution with position sensing down to the decimeter range.

“It’s about ensuring a precise threading process and avoiding accidents. This is only possible with a highly accurate and reliable position. “Matthias Overbeck, Fraunhofer IIS

According to the Fraunhofer Institute, the system that has now been demonstrated should also work under bridges and tunnels. Because for short periods of time it is possible to bridge signal interruptions so that driver intervention is superfluous under certain conditions.
