Mercedes-Benz test four driverless cars difficult to solve!

School buses, lane-specific tiles, ride-in lanes, and speed limit signs, how do autopilot cars recognize these things? For Mercedes-Benz researchers is a big challenge.

At the "IntelligentWorldDrive" event, Mercedes-Benz implanted autopilot technology for the S-Class. Researchers found that when self-driving cars are driven in the United States, the four things above will make the driverless cars feel confused.

school bus

In the United States, school buses have a special status. Once the school bus stops, the red sign glows and the nearby car must stop immediately. Even cars that come in the opposite direction must stop. Mercedes-Benz is trying to find a way to find a new way for autopilot cars to identify school buses and determine whether the school bus is manned.

Lane dividing tiles

In the United States, some states do not use paint to draw road signs. They use raised plastic or ceramics. If it is painted with paint, the internal system of a self-driving car can be easily identified. If ActiveLane Keeping Assist and Active Steering Assist systems, it is difficult to identify. California is working hard to clear the tiles used to divide lanes to ensure uniform lane markings. Mercedes-Benz hopes other states can learn.

Shared driveway

At certain locations on the road, there are sometimes high-occupancy lanes and high-occupancy lanes, which may be on the left, right or middle of the road. These lanes are distinguished by metal guardrails or two uninterrupted yellow lines, often with different signs. Mercedes-Benz self-driving cars are difficult to distinguish. Mercedes-Benz is trying to optimize the camera and radar systems so that they can distinguish between lanes. In addition, Mercedes-Benz is also developing a new technology that will allow autopilot cars to automatically determine whether they can use the shared drive lane.

Speed ​​sign

In the United States, the speed signs have different shapes and sizes, and they are not the same everywhere in the world. Mercedes-Benz self-driving cars are difficult to distinguish.
