Safety First Listening Engineer Explains Seat Belt & Airbag System
With the continuous improvement of people's living standards, vehicles have become the standard for every family. However, the traffic safety problems that ensued have greatly plagued people, especially how to reduce the damage of occupants in the process of vehicle collision. The degree has always been the focus of automotive research. This small editor had the honour to come to Changchun on the 25th anniversary of FAW-Volkswagen. He also visited the collision laboratory and learned some relevant knowledge from FAW-Volkswagen engineers.
â— Essential airbag
As an occupant safety protection system, the airbag is mainly used to prevent people from directly colliding with the interior of the vehicle when the vehicle is collided, thereby protecting the safety of the vehicle personnel to some extent.
Airbag systems generally include airbag bags, impact sensors, inflation systems, controllers, and warning lights. Its work mainly depends on the sensor collecting the signal of speed and acceleration, and sending the signal to the controller. The controller judges whether it is necessary to open the airbag. When the controller determines that the airbag needs to be turned on, it will send an ignition command to the gas generator and quickly generate enough gas to fill the airbag until the airbag is fully opened.
The airbag can detonate the airbag under various combinations of conditions to avoid airbags from popping out in unnecessary situations under similar crash operations.
"Airbags should burst when they should burst, they shouldn't burst anytime when they shouldn't burst, and reduce the gray area. This is our requirement for airbags." An engineer engineer at the FAW-Volkswagen Collision Laboratory told us that the gray area It is the case that some systems cannot accurately identify whether they should be exploded.

In the experiments of airbags and seatbelts, car manufacturers have spent a very large amount of money on the cost of doing what they can do. Although these investments are invisible to us, they are actually passed through countless experiments and will be safely delivered to customers. Therefore, the expensive car has its own reason, but no matter how safe the car is, If the occupant does not wear the seat belt as required, the danger is still unavoidable.
â— Summary
I remember that the director of FAW-Volkswagen Collision Laboratory was very helpless to say that engineers spent a lot of money and a lot of energy on airbags and seat belts, trying to bring five-star safety to all drivers and passengers, but still see the news There are many people who are injured or even lost their lives because they are not wearing seat belts. They also see people on the road who do not wear seat belts. It is a pity that it is not easy to spend so much money on a car. How do you say to buy the "peace" to it.
