Electronic airbags are mainly composed of airbag sensors, anti-collision airbags and electronic control devices. The driver’s side collision avoidance airbag is installed in the steering wheel; the passenger side collision avoidance airbag is generally installed on the dashboard. The airbag sensors are respectively installed on 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. Airbag components are mainly composed of airbags, gas generators and igniters. For example, the electronic control device is used for data acquisition and data processing, to diagnose the reliability of the airbag, to ensure that the ignition signal is issued in time when the preset value is reached, and the ignition is timed to ensure that the driving gas generator has a large enough driving current.
