Detailed description of the invention
Elaborate below in conjunction with the specific embodiment of accompanying drawing to the invention.
As shown in Figure 1, a kind of constrained system of automatic adaptation passenger type, comprise frontal airbags 8, leg air bag 9, installing side airbag 10, side gas curtain 11 and safety strap 12, described frontal airbags 8, leg air bag 9, installing side airbag 10, side gas curtain 11 and safety strap 12 are arranged on vehicle rotine positioning, also comprise Real-time Image Collecting System 3, vehicle-state and speed of a motor vehicle interface 4, seat front sensor 5, seat rear sensor 6 and control unit 7 in frontal collisions detecting sensor 1, side collision detection sensor 2, car;
Described vehicle-state and speed of a motor vehicle interface 4 inside are provided with vehicle running state sensor and Vehicle Speed sensor;
Described frontal collisions detecting sensor 1 is placed in car body head, described side collision detection sensor 2 is placed in car body sidewall, in described car, Real-time Image Collecting System 3 is placed in Inner Front End top, compartment and the position relative with chaufeur, can detect that the position of real-time condition and chaufeur basic document in car is as the criterion, described vehicle-state and speed of a motor vehicle interface 4 are fixed on autopilot control panel, described seat front sensor 5 and seat rear sensor 6 are separately fixed at the front and rear of seat, and described control unit 7 is arranged on interior;
The input end of described control unit 7 is connected with Vehicle Speed sensor with the vehicle running state sensor in Real-time Image Collecting System 3, seat front sensor 5, seat rear sensor 5, vehicle-state and speed of a motor vehicle interface 4 in frontal collisions detecting sensor 1, side collision detection sensor 2, car respectively, and the mouth of described control unit 7 is connected with the startup control setup of frontal airbags 8, leg air bag 9, installing side airbag 10, side gas curtain 11 and safety strap 12 pretension control setup respectively.
As shown in Figure 2, the principle of design of the invention is: by seat front sensor 5 and seat rear sensor 6 Real-Time Monitoring occupant weight and passenger riding position; Collect data by Real-time Image Collecting System in car 3, these data comprise occupant's head and the location gap of chest apart from air bag, the location gap etc. of occupant side square shoulder portion distance car door, send data in the determining device in control unit and carry out data analysis; Vehicle-state is detected in real time by vehicle running state sensor and Vehicle Speed sensor and frontal collisions detecting sensor 1 and side collision detection sensor 2; The information obtained according to said apparatus calculates the spacing between each position of occupant and each air bag by data analysis; by detonate moment and the limiter grade of the information determination air bag and safety strap such as whether to collide to the occupant's attitude information collected and vehicle, to all kinds of occupant to reach occupant restrain system can be cushioned to greatest extent and be protected effect.
As shown in Figure 3, described seat front sensor 5 and seat rear sensor 6 measure mass M and the buttocks distance seat slide distance BL foremost of the superior member of seat; In described car, Real-time Image Collecting System 3 measures occupant's chest and air bag spacing CL, head and air bag spacing HL, above the waist height UL and shoulder in real time apart from side B intercolumniation SL; Whether described vehicle running state sensor measurement vehicle is in running order, if it is output signal 1, is not then output signal 0; Whether described frontal collisions detecting sensor 1 detects vehicle front and collides, if had, exports FT=1, if not, exports FT=0; Whether described side collision detection sensor 2 detects vehicle side and collides, if had, exports ST=1, if not, exports ST=0;
By measuring occupant weight M and upper part of the body height UL reckoning occupant thigh length, according to occupant's thigh length, buttocks, apart from seat slide, distance BL and seat instrument carrier panel spacing can calculate occupant's knee distance meter dash board relative spacing KL foremost;
By recording occupant weight M and upper part of the body height UL according to Chinese's sign feature medical statistics table reckoning occupant size, according to Vehicle Speed V and occupant size, by inquiry new car demarcate safely setting table draw occur traffic accident time to the best air bag burst time point of this passenger protection, and at this moment chest apart from safety air bag spacing CLX, head apart from safety air bag spacing HLX, knee apart from knee air bag spacing KLX and shoulder apart from side B intercolumniation SLX, and by determining device corresponding in these four parameters input control units;
What whether be greater than that constrained system starts floor V0 by Vehicle Speed judges whether signal and frontal collisions detecting sensor 1 record collision alarm and provide the signal whether air bag and safety strap allow to detonate, as long as and vehicle is in running order, this air bag and safety strap allow the signal detonated once provide and will be kept;
Record KL in real time once be less than KLX if above-mentioned, and seat records occupant weight M>0, and central collision occurs, air bag allows time break to provide, and this leg air bag 9 will be detonated;
If above-mentioned in real time once record CL and be less than CLX or HL and be less than HLX, and seat records occupant weight M>0, and central collision occurs, and air bag allows time break to provide, and this frontal airbags 8 will be detonated;
By recording occupant weight M and upper part of the body height UL reckoning occupant size size, according to Vehicle Speed V and occupant size's size table look-up draw occur traffic accident time to this member protection best safety strap limiter value, and allow time break to provide once there is frontal collisions safety strap, and seat records occupant weight M>0, then this safety strap limiter will be set to the best limiter value of gained of tabling look-up;
Once vehicle generation frontal collisions, safety strap allows time break to be presented, and seat records occupant weight M>0, then this safety strap pretension powder charge will be detonated;
Detect whether side collision occurs by side collision detection sensor 2, once there is side collision in vehicle, and seat records occupant weight M>0, installing side airbag 10 allows time break to be presented, as long as this signal is once seat also have occupant and M>0 after providing, then this signal is kept always; If record SL in real time above-mentioned and be less than SLX, and installing side airbag 10 allows time break to provide, the installing side airbag 10 of this correspondence will be detonated.
Above design consideration passenger type carries out conservative control to safety strap pretension amount, limiter threshold value, airbag aeration amount and inflation speed etc., and reaching occupant restrain system can provide the design goal cushioning and protect effect to greatest extent to all types of occupant.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
