Where can we find driverless cars

Autonomous driving from A to Z: Part 2

Test tracks

On some test tracks in this country, highly or fully automated level 3 and 4 vehicles are allowed to drive in normal traffic. In order to test the cars in as different situations as possible, the routes range from motorways to federal and country roads to urban areas and housing estates. For example, there are self-driving cars in downtown Hamburg and on the A9 motorway in Bavaria. There is also an international test area in the border triangle between Germany, Luxembourg and France. It should show how the cars cope with different traffic lights, signs and cell phone systems.


When an autonomous vehicle detects an object on the road via a sensor, it has to assign within a fraction of a second whether it is a person or something else. Give it Uncertainty values information on how reliable the current AI forecast is. In order to find out how certain an autonomous vehicle is in its assessment, one must precisely determine the uncertainty. In this blog article we compare four methods that are suitable for this.

Road Signs

In principle, autonomous vehicles can identify conventional traffic signs using image recognition. But that doesn't always work out without any problems. If a sign is only slightly rotated, the vehicle can refer to it, even though it is intended for the cross street. Machine perception is also prone to accidentally or maliciously changed signs. What appears to be an unsuspicious spot to the human eye can lead to the confusion of the speed limit with a stop sign in an autonomous vehicle. Approaches to solving this problem range from special "training" of vehicles to road signs that are invisible to humans.

Car wash

Just send the self-driving car to the car wash around the corner? Unfortunately it's not that easy. Autonomous vehicles are not suitable for conventional car washes. Sensors and electronics are too sensitive. Brushes and soap could destroy the sensors or at least prevent them from working properly after washing. So far, people have been washing the vehicles. There are initial approaches to at least partially automatically cleaning the sensors. But it will be a long time before hand washing is no longer necessary.
