Problems solved by technology

[0004] The existing technology cannot completely judge whether the occupants are in a safe state based on the information of the occupants and the driving state of the vehicle. Therefore, in the existing road accidents, the airbag still frequently injures (or kills) the occupants.

Embodiment Construction

[0015] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0016] On the basis of the existing intelligent airbag, the present invention simulates all the situations that the airbag may accidentally injure the driver and occupants through a computer, and stores all possible accidental injury data on the airbag ECU. When the vehicle is driving on the road, the information of the driver and passengers and the vehicle speed are collected through sensors and cameras, and the built-in chip and program are used to judge whether the airbag detonation will hurt the driver and passengers at this time. If it is possible to hurt the driver and passengers, Then remind the driver and passengers to take corresponding measures, such as reducing the driving speed, or moving the seat to a safe...

Abstract

The invention discloses a control method for an accidental injury prevention safety air bag. On the basis of an existing intelligent safety air bag, analogue simulation is conducted through a computer for all situations where safety air bags may cause accidental injuries to drivers and passengers, all possible accidental injury data are stored in a safety air bag ECU, when vehicles run on roads, information of the drivers and the passengers and the running speeds of the vehicles are collected through sensors and cameras, whether the drivers and the passengers can be hurt or not when the air bags are detonated at the moment is judged through built-in chips and programs, if the drivers and the passengers can possibly be injured, the drivers and the passengers are reminded to take corresponding measures such as the measure of decreasing the running speed or the measure of moving the sitting positions backwards to the safe area, and if the drivers and the passengers pay no attention to the reminding, the air bags are temporarily closed, and meanwhile the states of the drivers and the passengers are recorded. By means of the preset judgment technology, if the air bags may cause accidental injuries to the drivers and the passengers, the drivers and the passengers are reminded to move to the safe area; if the drivers and the passengers continue to be in the unsafe state, air bag denotation is stopped.

Description

technical field [0001] The invention relates to a safety airbag, in particular to a method for controlling the accidental injury prevention safety airbag. Background technique [0002] Car airbags can pop out from inside the car in the event of a collision to prevent the driver and passengers from contacting hard objects inside the car, resulting in secondary collision damage. Since the airbag must be filled with gas in a very short time (usually about 30ms) after the collision, the airbag must be inflated with a huge inflation pressure when it is deployed. If the driver and occupant are in the deployment area of ​​the airbag during the airbag deployment stage, they may be injured by impact. [0003] At present, the technical solutions of airbags are to sense the collision intensity through sensors, and if the collision intensity reaches a preset level, the airbag will be detonated. Existing automobile airbags are all matched and designed according to the relevant laws and...
