Problems solved by technology

[0004] However, the inventor found that with the development of automatic driving, the seat position and sitting posture of the occupants will change greatly, and the airbag components in the existing vehicles are independent of each other work, cannot cooperate with each other, cannot support each other, and cannot provide protection for occupants of different sizes in different seating positions and different sitting postures for different collision situations

Embodiment 1

[0061] Please refer to figure 1 To understand the following embodiments of this system, the system for enhancing the safety of drivers and passengers through airbags includes: an in-vehicle observation system 1 , an inflatable restraint system 2 , an integrated safety domain control unit 3 , and a collision prediction system 4 .

[0062] Wherein, the in-vehicle observation system 1 is used to collect one or a combination of the attitude data of the occupants in the vehicle, the body shape data of the occupants in the vehicle, the posture data of the seats in the vehicle, and the mental state data of the occupants in the vehicle.

[0063] The inflatable restraint system 2 includes a plurality of airbag assemblies 21, wherein the airbag assembly 21 may be composed of an airbag, a gas generator and an igniter, and the gas generating agent in the gas generator is ignited by the igniter to generate a large amount of gas to The airbag is inflated, so that the airbag will be deployed...

Embodiment 2

[0090] Embodiment 2 can also add the following systems or modules on the basis of the foregoing embodiment 1, and only the added parts will be described below.

[0091] The collision prediction system 4 also includes a vehicle networking module 44, which can provide distance information between vehicles through communication with other vehicles and network systems, wherein the vehicle networking module 44 can communicate with the vehicle external information monitoring module 41 The external information of the vehicle body is jointly provided, and the modeling unit continuously updates and models the obstacles around the vehicle body in real time according to the external information of the vehicle body.

Embodiment 3

[0093] Embodiment 3 can also add the following systems or modules on the basis of the foregoing embodiment 1, and only the added parts will be described below.

[0094] Among them, the integrated safety domain control unit 3 provides collision judgment according to the mental state data of the driver and passengers and the collision probability. The collision judgment includes: judging whether the driver and passengers cannot notice the possibility of a collision. If the possibility of collision occurs, a reminder strategy is formulated. Wherein, the reminder strategy includes: pre-inflate the airbag or repeatedly inflate and deflate the airbag before the collision moment. It should be noted that the pre-inflation referred to here can be a small amount of inflation in the airbag through a suitable inflation device such as a high-pressure gas storage tank. It can be understood that the small amount of inflation refers to the inflation of the airbag when the collision occurs. q...

Abstract

One purpose of the invention is to provide a system for enhancing the safety of a driver and passengers through an air bag, and the system can provide adaptive protection for the passengers at different seat positions and in different sitting postures; the invention further aims to provide a method for enhancing the safety of the driver and the passengers through the air bag. Another object of the invention is to provide a computer readable medium. The system for enhancing the safety of the driver and the passengers through the air bag comprises an in-vehicle observation system, an inflation restraint system, a collision prediction system and an integrated safety domain control unit. The integrated safety domain control unit formulates an explosion strategy according to data transmitted by the in-vehicle observation system, the inflation restraint system and the collision prediction system so as to selectively inflate at least one safety air bag assembly and control the inflation amount of the inflated safety air bag assembly.

Description

technical field [0001] The present invention relates to a system and method for enhancing the safety of drivers and passengers through airbags. Background technique [0002] The airbag system is a passive safety protection system, which is usually used in conjunction with seat belts to provide effective crash protection for occupants. According to statistics, when a car collides, the car airbag can reduce the head injury rate by 25%, and the face injury rate by about 80%. [0003] In order to improve safety, more types of safety airbags and their setting positions are provided in some vehicles, as the patent application with publication number CN104691487A records a kind of safety airbag assembly, which provides a safety airbag assembly arranged on the head, trunk and knees. The front airbags deploy in the event of a collision and provide uniform structural cushioning energy and protection for the head, torso and lower limbs of the front passenger. [0004] However, the in...
