Model airbag position

The Modely airbag is located on the steering wheel to protect the driver airbag, and the passenger airbag is located on the passenger dashboard. The safety factor of Tesla Model Y is also particularly high. Both models are equipped with five airbags. It is also a pity that the active braking system and the road departure warning system are not equipped with fatigue driving tips and traffic road identification systems.

Development history of airbag

The airbag was first proposed by Hetrick in August 1953, and obtained the patent of "automobile buffer safety device" in the United States. With the formulation of automobile safety standards in various countries, the deployment rate of airbags is getting higher and higher. In Europe, America, Japan and other countries, the equipped rate of automobile airbags is close to 65,438+0,000%.

It is mainly composed of airbag sensor, anti-collision airbag and electronic control device. The driver side anti-collision airbag device is arranged in the steering wheel; The passenger side anti-collision airbag device is generally installed on the instrument panel. Airbag sensors are respectively installed at the left, right and middle of the cab partition; The airbag sensor and airbag system in the middle are installed together with the electronic control device. The airbag module is mainly composed of airbag, gas generator and igniter.

The electric control device is used to collect and process data, diagnose the reliability of the airbag, ensure that the ignition signal is sent out in time when the preset value is reached, and ignite at the appropriate time to ensure that the driving gas generator has enough driving current.
