Profile: Securing an accident scene

 

Warning triangle robot

Function

A robot is carried at the rear of the vehicle. In the event of a breakdown or accident, this leaves the vehicle and automatically puts out an illuminated warning triangle at a requisite distance to warn other road users.

In detail

In an emergency, a small robot (length/width/height: 38/26/14 cm) automatically emerges from its drawer-like box in the vehicle's underbody. As soon as it has left the stationary vehicle, the warning triangle is automatically unfolded. Later the robot returns to the vehicle with the triangle folded. If required the robot can also be deployed by the driver when stationary. Activation of the warning triangle could take place after receipt of a crash signal or via the backend server. The robot is charged via spring contacts in its box.

Additional function

The warning triangle can no longer be forgotten, and there is less personal risk when positioning it. Moreover, automatic deployment is of relevance for driverless vehicles.

Sensors

Video cameras in the robot for orientation with the help of line and crash barrier recognition plus GPS information. Infrared LEDs show the robot the way back to the vehicle.

 

Roof warning triangle

Function

When the warning triangle robot leaves the vehicle after an accident or breakdown, a warning triangle automatically folds out of the vehicle's roof. Thanks to its prominent position, it is able to warn other road users very effectively. The warning triangle can also be operated manually by a switch in the interior.

In detail

The warning triangle is integrated into the carrier of the communication LEDs, and normally lies flat on the roof. It is erected by electrically driven, threaded spindles connected to the two lower corners of the warning triangle by hook-shaped fittings. Once the danger has passed it is folded down again. The warning triangle likewise has LED lights.
