Detailed Description
The invention is further illustrated by the following examples:
the present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present invention, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
As shown in fig. 1, the side split curtain airbag of the present invention has independently controllable side curtain airbags for each row of passengers of a vehicle, each airbag does not interfere with each other and has no related structural connection, and each airbag can independently perform protection region design, arrangement and ignition timing control. Each row of side curtain airbags has its own independent inflator for its squint inflation. Also, the side curtain airbag of the present invention does not get stuck or dig into the A, B, C pillar inner panel.
Specifically, aiming at the side protection area positions of different vehicle types, independent side curtain type airbags are designed at each row of seats, each row is subjected to ignition control by an independent gas generator, the side curtain type airbags of each row can be matched with a corresponding seat passenger identification system, the seat passenger identification system is used for judging whether a seat takes a passenger or not and sending information to an airbag controller, each side curtain type airbag is also respectively connected with the gas generator, the airbag controller is respectively connected with the plurality of gas generators in a control mode, and the plurality of gas generators are controlled by the airbag controller to determine whether the side curtain type airbags are ignited or not in the collision process, for example, the side curtain type airbags at the position take the corresponding passenger, and the side curtain type airbags at the position are ignited in the collision process of the side; the side curtain airbag does not ignite at this position during a collision on that side without the corresponding occupant being seated at that position.
The side curtain airbag arrangement is performed according to the vehicle safety development target, and it is usually necessary to arrange the first row side curtain airbag 4 and the second row side curtain airbag 5, and the seven-seat vehicle type determines whether or not the side curtain airbag 6 is arranged as necessary. The first row of side curtain airbags 4 and the first row of gas generators 7 are disposed between the a pillar 1 and the B pillar 2 of the vehicle, and the remaining side curtain airbags and gas generators are disposed between the B pillar 2 and the C pillar 3 of the vehicle at respective row positions.
When the algorithm of the safety air bag controller is calibrated, corresponding ignition time is determined according to the configuration situation of each row of side curtain type safety air bags, and meanwhile, the side curtain type safety air bags are matched with a seat passenger identification system, when passengers at the position take the side curtain type safety air bags, the safety air bags are normally ignited when the ignition conditions of the safety air bags are met, when no passenger is at the position, a non-ignition strategy can be selected, and the side curtain type safety air bags at other positions are analogized.
The seat occupant recognition system can recognize whether the seat is occupied by an occupant, and also recognize whether an adult or a child is occupied based on the weight. If the passenger sits on the right side of the five-seat vehicle and no person sits on the right rear seat, only the right front air curtain is detonated and the right rear exhaust curtain is not detonated when a right side collision occurs. By analogy, as long as a passenger sits on the seat at the corresponding position, the side air curtain corresponding to the position is detonated when collision occurs.
The seat occupant recognition system recognizes whether or not an occupant is seated in a seat, and there are generally two recognition methods: the safety belt is used for judging whether the safety belt is fastened or not, the occupied sensor is arranged in the seat cushion for identifying whether the seat is taken or not, the information can be sent to the safety airbag controller, and the safety airbag controller determines whether the safety airbag corresponding to the position is detonated or not through an identification result.
The first recognition mode is as follows: and judging whether the safety belt is fastened or not. The seat passenger identification system comprises a safety belt identification module which is used for identifying whether a safety belt is fastened at the corresponding seat or not, further identifying whether the seat is taken or not at the position and sending information to an air bag controller.
The second recognition mode is as follows: the seat is judged by arranging an occupancy sensor inside the seat cushion. The seat occupant identification system comprises an occupancy sensor arranged inside a seat cushion and used for identifying whether a passenger sits at a corresponding seat and sending information to an airbag controller.
The seat occupant recognition system further comprises a weight recognition module which can recognize whether an adult or a child is seated according to the weight value.
The safety airbag controller is internally provided with a front collision sensor and a side collision sensor which are used for collecting collision data information, and when collision occurs, the collision data information collected by the sensors and the whole vehicle collision test data can be calibrated, if the ignition threshold is reached, the corresponding safety airbag is ignited. Specifically, the airbag controller algorithm calibration and ignition moment determination are based on a whole vehicle crash test in a development stage. The method comprises the steps of firstly carrying out a whole vehicle collision test, collecting collision test collision data through a front collision sensor and a side collision sensor, carrying out algorithm calibration according to the collision test data, carrying out a verification stage collision test, inspecting and checking a calibration result, adjusting and locking a calibration parameter according to actual conditions, determining an ignition threshold, and controlling a gas generator to ignite the airbag when the ignition threshold is reached by an airbag controller.
The front-rear split curtain type safety air bags are adopted, different gas generators are used for controlling the safety air bags at different positions to explode, structural design can be carried out aiming at different collision areas so as to achieve the effect of protecting passengers in the vehicle, particularly the vehicle type with a third row of seats, the side split curtain type safety air bags have better protection effect on the passengers in the third row, and meanwhile, under the collision mode of a rigid barrier overlapped by 25% on the front surface, the front-row curtain type safety air bags are larger in coverage area and better in protection effect.
