The invention relates to an air bag control device for judging protecting types based on weight. The air bag control device comprises an air bag electronic control unit (ECU), wherein the air bag ECU is connected with an acceleration sensor, a seat belt sensor, a seat pressure sensor, a vehicle velocity sensor, a seat belt pretensioner, a main air bag, a secondary air bag and an external power source. According to the air bag control device disclosed by the invention, passenger weight information is acquired by the seat pressure sensor, according to the acquired passenger weight information, passenger types are identified, and the information of multi-pass external sensors is combined, so that the ECU can automatically adjust parameters including the size of a deflation hole of an air bag, the initiation time of the air bag, the mass flow rate of the air bag, the length of a drawstring of the air bag and the like according to different passenger types and the information of the sensors, and in a colliding accident, different kinds of passengers can be best protected.
Description
technical field [0001] The invention relates to the technical field of airbags, in particular to an airbag control device for judging protection types based on weight. Background technique [0002] Car airbags have saved the lives of countless occupants since their inception. According to a report by the United States Government Accountability Office (US-GAO) in 2001, when a car has a frontal collision, the use of front airbags alone can Reduce the serious injury rate of occupants by 14%, while using seat belts and airbags at the same time can reduce the serious injury rate of occupants by 50%. However, since the airbag is developed based on the 50th percentile of adult males, it cannot provide the best protection effect for all types of occupants during the detonation process. [0003] When the safety belt is not worn in a high-speed collision, the explosion of the safety airbag will hurt the occupant, but if there is no safety airbag, the occupant will definitely collide ...
