4active Systems/4a

Overview

4activeSystems GmbH works in the field of active vehicle safety to develop and produce advanced testing technologies and target objects like pedestrian-, bicyclist-, scooter- or other vehicle-dummies. Our challenge is to simulate a realistic accident situation and displaying the dummies in a realistic way with regard to different sensor systems like radar, infrared, mono- or stereo-cameras.

Our Solutions

4activeSystems focuses on dummies and testing systems for active vehicle safety. Their suite of testing equipment include easily transported mobile products that support several vehicle speeds, static dummies crashable up to 60km/hr and modular articulated dummies that only need minutes for part replacement and minor repairs after rigorous testing.

Test Equipment

4activeSB

The mobile dummy test rig
System installation is performed by two people in about half an hour. The system works battery powered, with a minimum operating time of 10 hours at low temperatures. Platform speed of 20km/h

4activexb2

4activeXB

Extended range surfboard platform
The mobile test rig 4activeXB can be easily transported. The system needs no fixed power supply, it is powered by a 2kW generator. Platform speed 50 km/h.

4a-fb

4activeFB

GPS controlled platform with special materials
Offers a very low radar cross section used for testing AEB VRU scenarios. Extremely low profile and is very robust, can be driven over by passenger and commercial vehicles. Speeds up to 50 km/h (72km/h)

Obstruction Wall

Flat uniform surface with properties similar to brick wall.
The obstruction wall represents a permanent full view blocking obstruction from the ground up between vehicle and bicyclist, running parallel with the bicyclist path.

Test Dummies

pA-adult

4activePA

Pedestrian adult and child articulated dummy
Is detectable by radar, infrared and camera sensors, also the Micro Doppler spread is humanlike.

bs-eu45

4activeBS

Adult and child static bicyclist dummy
Has rotating wheels for realistic characteristics. RCS,IR, visual properties are humanlike. Cyclist speed 35km/h

moped45

4activeMC

Scooter test dummy
The properties are realistic for radar and camera systems. The target is crashable. There are rotating wheels for better RCS detection.

motorbike90

4activeMB

Motorbike test dummy
Has rotating wheels, for more realistic testing. The rotating wheels are spare parts and easy to change.
