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

ACU airbag controller

Use Car Model:Wuling New Energy-G105-3
SAIC-GM-Wuling-E50

The airbag control unit is a basic passive safety electronic system for car manufacturers in emerging markets. By receiving collision acceleration signals from external and internal sensors and calculating them internally, when a serious collision occurs in the vehicle, an ignition current is sent out to ignite the airbag and seat belt pretensioner, so that the air bag and seat belt can more effectively reduce the secondary Collision damage to the occupants, 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 TI solution, supporting up to 4-channel ignition circuit

Main control: Adopt main + auxiliary dual MCU design to further ensure the stability of the controller
