Currently, the working principle of automotive safety airbags involves sensors detecting collision information when a vehicle experiences a traffic impact. These sensors then immediately send an impact signal to the control unit of the vehicle's safety airbags. Upon receiving the sensor's signal, the control unit measures the current deceleration. If the deceleration exceeds a predetermined value, it commands the inflation device of the safety airbags to ignite the ignition device, resulting in an explosion.
The rapid inflation of the airbags from the explosion helps prevent collisions between the vehicle's occupants and objects such as the dashboard, steering wheel, and cabin, thus protecting the lives of passengers. However, the current safety airbags still have room for improvement in terms of their protective performance.
The newly disclosed patent by Huawei introduces a control system and control method for safety airbags in transportation vehicles, aiming to address the issue of inadequate protective performance of airbags.
According to the patent abstract, the proposed solution includes a detection device and a controller in the control system. The detection device is used to sense the seating posture of the occupants. When instructed to deploy the safety airbag, the controller determines the seating posture of the occupant based on the sensed information and controls the airbag's deployment from its folded state to the target deployed state, which corresponds to the occupant's posture.
Furthermore, the safety airbag described in the patent can also provide protection for rear-row occupants. For example, the seating posture information mentioned earlier can include the angle between the seat and the seat cushion or the seat coordinates. By considering different seating postures, the airbag can adjust its deployment accordingly, thereby improving its protective performance for different occupants.
