The new patent of Huawei airbag has been announced, and the deployment state of the airbag can be adjusted according to the sitting position.
CTOnews.com June 24 news, Huawei Technology Co., Ltd. applied for "airbag control system and control methods, means of transportation" patent announced.
The CTOnews.com obtains from the patent abstract, and the embodiment discloses a control system, a control method and a vehicle of the airbag, which relates to the field of transportation and solves the problem of poor protection performance of the airbag. The specific scheme is as follows: the control system includes a detection device and a controller, and the detection device is used to detect the passenger sitting posture information; when instructing to deploy the airbag, the controller determines the occupant sitting position of the occupant to be protected according to the occupant sitting posture information, and controls the airbag to expand from the folded state to the target deployment state, which corresponds to the occupant sitting position.
The airbag can protect the passengers in the back row. For example, the aforementioned occupant sitting posture information is the angle between the seat and the cushion and the seat coordinates. In this way, the sitting posture information of the occupants is different, the deployment state of the airbag is different, and the protection performance of the occupants is improved.
It is understood that when the car has a traffic collision, the sensor can feel the impact information and immediately send the impact signal to the control unit of the car airbag. When the car airbag control unit receives the signal from the sensor, it will detect the current deceleration, and if the deceleration exceeds the predetermined value, it will issue instructions to the inflatable device of the airbag, ignite the ignition and cause an explosion.
Among them, the gas produced by the explosion quickly fills the airbag to avoid collisions between the driver and the front dashboard, steering wheel, carriage and other objects, thus protecting the lives of the people in the car. However, the protection performance of airbags to occupants needs to be improved.
