The invention discloses a safety air bag device on a passenger vehicle. The safety air bag device comprises an air bag, an air generator, a side collision sensor, a detector and a safety air bag controller. The side collision sensor collects collision acceleration information of the collision side of the passenger vehicle; the detector detects the occupancy state of each seat in the passenger vehicle; the safety airbag controller receives collision acceleration information collected by the side collision sensor and calculates the collision acceleration information, and when the calculation result reaches a point explosion threshold value, the safety airbag controller judges that passengers are in the same row of two seats according to the occupancy state of each seat, the safety airbag controller controls the air generator to inflate the air bags matched with the row of seats. The formed airbag is located between passengers on the two seats of the row to isolate passengers on the two seats of the row. When side collision occurs, passengers in the same row of passenger vehicles can be prevented from colliding with one another due to impact force, and effective safety protection is provided for passengers far away from the collision side in time.
本发明公开了一种乘用车上安全气囊装置,包括气袋、气体发生器、侧碰传感器、检测器和安全气囊控制器;侧碰传感器采集乘用车的碰撞侧的碰撞加速度信息;检测器检测乘用车内的各座椅占用状态;安全气囊控制器接收侧碰传感器采集的碰撞加速度信息并进行计算,当计算的结果达到点爆阈值时,安全气囊控制器根据各座椅占用状态来判断同排的两个座椅都有乘员时,安全气囊控制器控制气体发生器对与该排相配套的气袋充气,形成的气囊位于该排的两个座椅上的乘员之间,以隔离该排的两个座椅上的乘员。本发明能够在侧面碰撞发生时防止乘用车同排的乘员受到冲击力而相互撞击,及时为远离碰撞侧的乘员提供有效的安全保护。
