Method and apparatus for adjusting safety air bag control system

Abstract

The invention discloses a method and a device adjusting a security air bag control system, and aims to provide a method and a device that the explosion time of the security air bag can be amended in time when the position of a passenger is changed, an alarm can be given and explosion can be stopped when the position of the passenger exceed the setting security range, and the explosion of the security air bag can be stopped when the passenger does not wear seat belt, so the security air bag can exert the best protection effect. The device comprises the seat belt and the security air bag, wherein, a time delayer is arranged between a security air bag control module and an air generator, a passenger position sensor is arranged on a meter panel of the vehicle and is connected with the time delayer. The method thereof is realized by that the change of the position of the passenger is measured to adjust the security air bag control system, and the error of the touching time of the security air bag aroused by the change of the position of the passenger can be amended. The device is used for the vehicle to protect the security of the passenger.

Description

technical field [0001] The invention relates to an automobile safety technology, in particular to a control system of a safety air bag. Background technique [0002] The airbag is a safety device used to protect the occupants of the car, which can effectively protect the occupants and reduce injuries when the vehicle collides. But the control module of existing safety airbag has already set the triggering time of the gas generator of safety airbag before leaving the factory, and the setting of this value is determined according to the normal position of seat, and in actual use process In different occupants, different occupants will adjust their sitting position according to their height, arm length, driving habits and comfort. The change of occupant's sitting posture will make the optimal triggering time of the airbag that has been set at the factory become inaccurate. , can not achieve the best protection effect, and even cause harm to the occupants; in addition, the airb...

AI Technical Summary

Problems solved by technology

But the control module of existing safety airbag has already set the triggering time of the gas generator of safety airbag before leaving the factory, and the setting of this value is determined according to the normal position of seat, and in actual use process In different occupants, different occupants will adjust their sitting position according to their height, arm length, driving habits and comfort. The change of occupant's sitting posture will make the optimal triggering time of the airbag that has been set at the factory become inaccurate. , can not achieve the best protection effect, and even cause harm to the occupants; in addition, the airbag is only an auxiliary protection measure for the occupant. Generally, the airbag can only play a protective role when the seat belt is in effect. When the occupant When the seat belt is not worn, the airbag cannot be recognized. At this time, it will not only fail to protect the occupant, but will cause injury to the occupant

Such as: Although the technology disclosed in the application number 200510088725.1 of the publication number CN1903615 announced by the Chinese Patent Office on January 31, 2007 "Ignition Signal Acquisition Device and Inspection Method for Safety Airbag System" can effectively control the opening of the safety airbag, but After the position of the occupant changes, the time when the gas generator of the safety airbag cannot be corrected in time to open, so as to bring into play the best safety effect of the safety airbag; the publication number CN1678476 application number 03820934.9 title announced by the Chinese Patent Office on October 05, 2005 Although the technology disclosed in the utility model application "airbag system with vehicle occupant sensor on the airbag" also involves real-time adjustment of the opening time of the gas generator of the airbag, this technology can only reduce the Avoid airbag injuries, and this technology does not consider the role of pre-tensioned seat belts. In fact, using this real-time adjustment method under the condition of installing pre-tensioned seat belts will not only fail to reduce injuries to the occupants , will cause more damage
