The 4activeXB is the big brother of 4activeSB, the official Euro NCAP test system for all AEB/AES-VRU tests. With the open standard concept, it is very easy to precisely synchronize with all driving robots and GNSS/Inertial systems (full synchro). Beside the standard VRU scenarios with pedestrian and bicyclist targets, it can move motorcycle (PTW) and vehicle targets (GVT) with a speed up to 50km/h. With the help of supercapacitor, the system can handle the needed high power with just a 2,5kW generator.
