Huawei has disclosed a new patent for a "control system and control method for safety airbags, and transportation vehicles." The application publication number is CN116279275A. It is reported that the disclosed embodiment of the patent presents a control system and control method for a safety airbag, applicable to transportation vehicles, addressing the issue of inadequate protective performance of safety airbags.
The specific solution involves a control system comprising a detection device and a controller. The detection device is used to detect the sitting posture information of the occupants. When instructed to deploy the safety airbag, the controller determines the sitting posture of the occupant to be protected based on the sitting posture information and controls the safety airbag to deploy from a folded state to a target deployed state corresponding to the occupant's sitting posture. This safety airbag can provide protection for rear-seat occupants. For example, the sitting posture information may include the angle between the seat and the seat cushion or the seat coordinates. By considering different sitting postures of the occupants, the deployment status of the safety airbag can be adjusted accordingly, thereby enhancing the protective performance for the occupants.
In the event of a collision, the sensors can detect the impact information and immediately send the collision signal to the control unit of the vehicle's safety airbag. Upon receiving the signal from the sensors, the control unit of the safety airbag examines the current deceleration. If the deceleration exceeds the predetermined threshold, it commands the inflator of the vehicle's safety airbag to ignite and generate an explosion.
