Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to an expandable safety airbag control device and method. Background technique [0002] The airbag control unit (Airbag Control Unit, ACU) is used to receive the collision signal and control the detonation of the airbag, and send the detonation command to the airbag. On the central channel of the car body. When a car collides, the airbag control device comprehensively judges the degree of vehicle collision, and decides whether to detonate related ignition circuits, such as seat belt pre-tightening, side airbags, side air curtains and other ignition circuits. The airbag control device is the core of the airbag system, and its key technologies are reflected in: accurate judgment of collision, precise control of ignition timing, super strong anti-interference ability and super high reliability and stability. [0003] In the existing technology, due to the different requirements of regul...

AI Technical Summary

Problems solved by technology

[0004] However, in practical applications, the development of a variety of airbag control devices with different circuits will require additional development time, additional component development and verification costs, and additional product costs, increasing the cost of vehicle airbag control devices. The cost of the airbag control device reduces the economy of the airbag control device for OEMs with small sales volume and many configuration steps
