ZF Design External Airbags Will Be Realized Immediately
For three decades, airbags or airbags have become mandatory safety components. Its function is vital, protecting the driver and passenger during an accident. The bag that expands on the front or side, prevents the human body from hitting the interior of the car.
As time went on, evolution also took place. Airbags on the body of the car are very interesting innovations. Reportedly, soon it will soon enter the market. A renowned German automotive supplier, ZF Friedrichshafen AG, who designed and developed this technology, confirmed it. According to them, the first car to implement external airbags was immediately launched in two years. However, there is no certainty which manufacturer will use it for the first time.
A decade of ZF developed this innovative air bag method. Introduced at the 2016 Consumer Electronics Show, then the 2018 Airbag symposium in Mannheim, Germany, November last year, the response was quite enthusiastic. As the vehicle population grows, it needs an improvement in safety devices. So that the impact of accidents on passengers is not fatal.
External airbags are designed to expand on the outside of the car. Get out of the bottom or side sill, and come out like a pillow to cover the door. The point is, protect the open area when a side hit occurs. But the way is different from interior airbags. The air bag does not expand immediately after an impact.
ZF uses radar, cameras and LiDAR sensors that actively monitor the surroundings of the car. The radar is responsible for measuring the distance of potentially crashing objects and the camera quickly detects them. The LiDAR sensor is used to make a detailed three-dimensional map of the vehicle's side area.
When an accident is detected that cannot be avoided, the airbag immediately expands less than 100 milliseconds. The bag, which is like a balloon, acts to absorb impact energy so it doesn't destroy the door. Based on the results of the ZF internal test, the impact into the cabin was reduced by 30 percent and reduced passenger injury rates to 40 percent.
The question is whether additional airbags are easily installed in the car. The placement of new modules, inflators, sensors and side sill designs needs to change many existing car designs. The solution is to make sensors with dual tasks for other safety features. In order to save more on production costs, the sensors used also function such as: lane departure warning, lane correction system, collision warning system, automatic emergency braking system, and others.
This year, ZF began a more comprehensive test phase. Direct demonstrations will be carried out, while testing the intelligence of sensors and computers. According to ZF, there are already several manufacturers that show interest. But there is no collaboration.
