ACU airbag controller-Zhejiang Itronsvs Technology Service Co., Ltd.

ACU airbag controller

Use Car Model:Chery-T1J
Foton Motor-EVB2/EVM2

The airbag control unit is a basic passive safety electronic system for car manufacturers in emerging markets. When a serious collision occurs in the vehicle, the ignition current is emitted to ignite the airbag and seat belt pretensioner, so that the air bag and seat belt can more effectively reduce the damage to the occupants from secondary collisions and better protect the occupants. The functions provided by this system include front and rear collision protection, continuous detection of restraint system status and notification of seat belt usage status through fault indication. The extended system can be equipped with additional side collision protection and seat belt reminder functions, and can receive messages from other parts of the car. information and store it with the EDR function.

Ignition: Using the National Core solution, a single chip supports a maximum of 16 channels of ignition circuits, with a maximum of 32 circuits reserved

Master control: using National Core MCU to further match the stability of the ignition chip

External sensor: supported
