Abstract
The invention provides an adaptive constraint method. The method includes the steps of allowing a first sensor set in a seat slide to measure positions of the front and rear of a driver's seat; allowing a second sensor set in a safety belt buckle to detect usage of a safety belt; allowing third sensors set on a front bumper and on the side to measure collision strength; allowing a fourth senor set on another seat to measure pressure of the seat; allowing an A/D (analog/digital) converter to convert output signals of the first, second, third and fourth sensors into a digital form; allowing a single-chip microcomputer to receive an output signal of the A/D converter, outputting a control signal according to the position of the driver's seat, usage of the safety belt, the collision strength and seat pressure, controlling electric reels to tension the waist-shoulder safety belts of the front seats, and controlling safety airbags at corresponding positions to open.
Description
Technical field
The present invention relates to vehicle electronics field, refer to a kind of self adaptation constrained procedure especially.
Background technology
The development of automobile not only creates great function to social economy, also brings important impact to the life of the mankind.Automobile become people trip main traffic instrument, its convenience be aircraft, steamer and train incomparable.
China is as newly emerging economy, and become global first automobile consumption state, the vehicle guaranteeding organic quantity of current China has broken through hundred million.Car is many, and road has been blocked up, and traffic accident also gets more and more.
Accident research shows, safety strap and safety air bag can reduce the chance of injury of navigating mate greatly, but due to the awareness of safety of chaufeur and passenger weak, usually safety belt buckling free, when airbag-releasing, can cause unnecessary injury.
How to make safety strap, safety air bag with the use of reaching best effect, reducing the chance of injury of chaufeur and passenger in traffic accident, is current problem demanding prompt solution.
Summary of the invention
For solving the problem, the present invention proposes a kind of self adaptation constrained procedure.
Technical scheme of the present invention is achieved in that
A kind of self adaptation constrained procedure, comprises the following steps:
The front and back position of driver's seat is measured by the first sensor be arranged in seat slide;
The second sensor smashed by being arranged on seat belt detects safety strap service condition;
By being arranged on the 3rd sensor measurement impact strength of front bumper and side;
The pressure on seat is measured by the four-sensor arranged on the seat;
By A/D converter, the output signal of described first sensor, the second sensor, the 3rd sensor and four-sensor is converted to digital form;
The output signal of described A/D converter is received by micro controller system, control signal is exported according to driver's seat position, safety strap service condition, impact strength and seating pressure, control Motorized retractor tension front stall three-point belt, the safety air bag controlling relevant position is opened.
The invention has the beneficial effects as follows: by being arranged on first sensor in seat slide, being arranged on the second sensor, the 3rd sensor being arranged on front bumper and side and the four-sensor arranged on the seat that seat belt smashs and measuring driver's seat position, safety strap service condition, impact strength and seating pressure, Single-chip Controlling Motorized retractor and safety air bag, the injury that further minimizing causes occupant because airbag deployment is improper, particularly for the front-row occupant that stature is less.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the diagram of circuit of a kind of self adaptation constrained procedure of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Accident research shows, safety strap and safety air bag can reduce the chance of injury of navigating mate greatly, but due to the awareness of safety of chaufeur and passenger weak, usually safety belt buckling free, when airbag-releasing, can cause unnecessary injury
The present invention by being arranged on first sensor in seat slide, be arranged on the second sensor, the 3rd sensor being arranged on front bumper and side and the four-sensor arranged on the seat that seat belt smashs and measure driver's seat position, safety strap service condition, impact strength and seating pressure, Single-chip Controlling Motorized retractor and safety air bag, the injury that further minimizing causes occupant because airbag deployment is improper, particularly for the front-row occupant that stature is less.
As shown in Figure 1, a kind of self adaptation constrained procedure of the present invention, comprises the following steps: the front and back position being measured driver's seat by the first sensor be arranged in seat slide; The second sensor smashed by being arranged on seat belt detects safety strap service condition; By being arranged on the 3rd sensor measurement impact strength of front bumper and side; The pressure on seat is measured by the four-sensor arranged on the seat; By A/D converter, the output signal of described first sensor, the second sensor, the 3rd sensor and four-sensor is converted to digital form; The output signal of described A/D converter is received by micro controller system, control signal is exported according to driver's seat position, safety strap service condition, impact strength and seating pressure, control Motorized retractor tension front stall three-point belt, the safety air bag controlling relevant position is opened.
Preferably, the quantity of described safety air bag is multiple, and described safety air bag comprises air bag and side air bag before twin-stage.
Preferably, above-mentioned micro controller system is dsp processor.
Above-mentioned dsp processor can be TMS320F2812DSP, and be 32 fixed DSPs, it has the AD data acquisition of EVA, EVB task manager and supporting 12 16 passages, has abundant Peripheral Interface, as CAN, SCI etc.The ADC module of TMS320F2812 is 12 bit resolutions, has the A and D converter of pipeline organization, the built-in dual-sampling hold circuit of TMS320F2812, and when keeping data acquisition, window has and independently calibrates control in advance.And allow system to same Channel-shifted repeatedly, allow user to perform over-sampling algorithm, this more traditional single transformation result adds more solution, is conducive to the precision improving sampling.There is multiple trigger source can start ADC conversion.Fast speed transfer time, ADC clock can be configured to 25MHz, and the highest sampling bandwidth is 12.5MSPS.When building data acquisition system with TMS320F2812, need not external ADC, avoid complicated hardware design.
The present invention by being arranged on first sensor in seat slide, be arranged on the second sensor, the 3rd sensor being arranged on front bumper and side and the four-sensor arranged on the seat that seat belt smashs and measure driver's seat position, safety strap service condition, impact strength and seating pressure, Single-chip Controlling Motorized retractor and safety air bag, the injury that further minimizing causes occupant because airbag deployment is improper, particularly for the front-row occupant that stature is less.
