Problems solved by technology

However, when the vehicle does not have any collision, if the restraint system is triggered by mistake, it will cause serious personal injury to the occupants, especially minors.
Especially when the vehicle is running at high speed, the accidental deployment of the airbag will hinder the driver's sight and pose a serious threat to the safety of the occupants.
[0003] The sensors on cars now have high precision and high reliability, but there may be various unpredictable failure risks during the production and use of the products

Embodiment 1

[0058] An anti-false trigger device for a passive safety restraint system for vehicle occupants, such as figure 1 and figure 2 As shown, the anti-false triggering device of the passive safety restraint system includes a data acquisition and processing system 100 and an ignition logic judgment software system 200 used in conjunction with the data acquisition and processing system. The data acquisition and processing system includes a vehicle body 101, an airbag Controller 102, alarm prompt module 103, central acceleration sensor 104, left front impact acceleration sensor 105, right front impact acceleration sensor 106, left side impact acceleration sensor 107, right side impact acceleration sensor 108, left column side impact acceleration sensor 109 and right The side column side impact acceleration sensor 110, the central acceleration sensor is arranged on the airbag controller, the left front impact acceleration sensor and the right front impact acceleration sensor are respe...

Embodiment 2

[0063] A method for preventing false triggering of a passive safety restraint system for vehicle occupants, such as Figure 4-Figure 7 Shown:

[0064] The method for preventing false triggering of the passive safety restraint system comprises the following steps:

[0065] S1, judging the front detonation event and the side detonation event of the vehicle body;

[0066] If the sensing thresholds of the central acceleration sensor on the airbag controller in the X direction and the Y direction are greater than a certain larger set value, then it is determined as a vehicle body front detonation event;

[0067] If the sensing thresholds of the central acceleration sensor on the airbag controller in the X direction and Y direction are greater than a certain smaller set value, then it is judged to be a vehicle body side detonation event, and the vehicle body side detonation event is divided into vehicle body left side detonation events. Side detonation events and vehicle body righ...

Abstract

The invention discloses a device for false triggering prevention of a vehicle passenger passive safety restraint system. The device comprises a data acquiring and processing system and a detonation logic judgment software system, acceleration sensors are arranged all over a vehicle body, data acquisition is carried out on acceleration sensor signals related to the restraint system arranged on thevehicle body, different data processing modes are formulated for different positions of the vehicle body where sensors are located, and once a safety airbag controller breaks down or a detonation sensor is abnormal, the detonation function is locked, and an early warning is given out. The invention further discloses a method for false triggering prevention of the vehicle passenger passive safety restraint system. After normal power-on, the data acquiring and processing system and the detonation logic judgment software system begin to acquire and process data of each acceleration sensor to perform collision detonation logic judgment. The method plays a role in early warning of the point explosion fault, improves the driving collision safety coefficient of the automobile, avoids a collisionblind area of an automobile body, improves the credibility of collision data, and is reasonable in collision data processing.

Description

technical field [0001] The invention belongs to the technical field of vehicle safety restraint systems, and in particular relates to an anti-mis-trigger device and method for a passive safety restraint system for vehicle occupants. Background technique [0002] If the vehicle encounters a violent collision while driving, it needs to trigger the passive safety restraint system (usually including detonation airbags, seat belts, etc.) to protect the safety of the occupants in the vehicle. However, when the vehicle does not have any collision, if the restraint system is triggered by mistake, it will cause serious personal injury to the occupants, especially minors. Especially when the vehicle is running at a high speed, the accidental deployment of the airbag will hinder the driver's sight and pose a serious threat to the life safety of the occupants. [0003] Nowadays, the sensors on automobiles have high precision and high reliability, but there may be various unpredictable ...
