Virtual Crash Zone
Today, it can be very difficult to manage the shorter crush zones of small vehicles. However, by using our 24GHz radar, this deficiency could be overcome, especially if the radar is combined with active seatbelts, pre-impact airbags and active vehicle structures. By using gas generator technology from airbags, active structures could stiffen those parts of the vehicle body that are hit in a crash and prevent the occupant compartment from collapsing. Active structures could also be used to distribute the crash forces in a more efficient manner, thereby lowering the crash load on the occupants.
