Abstract
The invention relates to the field of automobile safety, in particular to a method for presetting a seat before collision. The method comprises the steps that whether head-on collision of an automobile is inevitable or not is judged, and if yes, the next step is carried out; a safety airbag control unit sends an adjusting instruction to the seat; and seat parameters are adjusted to the factory default position. By means of the method, main parts of the electric seat can be proactively adjusted to the specific design positions before head-on collision, and thus a main restraint system provides the best safety protection for front-row passengers in the automobile.
Description
Technical field
The present invention relates to field of automobile safety, particularly to a kind of side of presetting seat before collision occurs
Method.
Background technology
Air bag system is the protection system of a kind of passive safety, and it coordinates with seat harness makes
With, can be that occupant provides effective Anti-bumping protection.
Air bag is made up of the gasbag folded, aerator, igniter and nitrogen solid particles.
It is through the shock degree of several groups of inductor sensing vehicles with foreign object being arranged in headstock, whether to determine
Want firing safety air-bag.When vehicle suffers frontal impact, it can be driven with protection at moment inflation
The person of sailing and front-seat passenger.During severe crash, air bag realizes rapidly the duty of 100% inflation；Non-
Time serious, air bag first inflates 70%, behind the interval of 0.1 second reinflated 30%, to reduce pressure,
The head making people more mildly contacts with air bag.Driver can be pressed close to when air bag explosion, but will not
People is made to suffocate, because air bag is from sensing, light a fire, ignite, inflate, breaking plate and go out to losing heart, whole
The time that process occurs only has 0.055 second to 0.065 second, almost completes whole within the time at a wink
Individual protection work.Due to air bag, to flick the speed of inflation very fast, if driver and passenger
Take fault, it will bring harm to health.
Collision warning systems be a can predict driving dangerous and risk of collision occur first 2.7 seconds to
Driver sends alarm, the system that prevention traffic accident occurs.At present, only some technical parameter examples
As headway (Time Head Way, THW), collision time (Time to Collision,
TTC) by the major parameter as assessment vehicle collision risk.Wherein TTC be collision avoid be
The most important parameters of system, TTC is this car to the spacing of front truck divided by the relative velocity between two cars,
If TTC will send sound less than the threshold value set, then conventional Automotive active anti-collision system
Tone alerts even self-actuating brake.
The application for a patent for invention of Publication No. CN104379411A discloses a kind of vehicle including air bag
Occupant restraint system, this air bag is received within the backrest of seat and in exhibition in folded state
Open state extends between two seats of vehicle.Air bag has regio pectoris and Head Section, and described regio pectoris is in side
The chest of face covering automotive occupant and described Head Section cover the head of automotive occupant in side.At air bag
On arrange first and fix section, this first is fixed section and is set directly on gas generator, and this gas is sent out
Raw device provides charge air conditioning for air bag, and arranges second and fix section, and this second fixes section in regio pectoris
On be arranged on first and fix between section and backrest upper end.
Summary of the invention
For solving the problems referred to above, a kind of method of presetting seat before collision occurs, thus in front
Before collision occurs, actively regulate each parameter value of automatic seat, provide optimal peace for front-row occupant in car
Full protection.
In view of this, the present invention provides a kind of method of presetting seat, described side before collision occurs
Method includes: judge whether vehicle frontal collision is inevitable, the most then enter next step；
Air bag control unit sends regulating command to seat；Seat parameter is adjusted to factory setting position
Put.
As can be seen here, the present invention can actively regulate each master of automatic seat before head-on crash occurs
Want part to the particular design position in development experiments or testing position so that air bag and
The major constraints system such as safety belt and steering column provides for passenger and is similar to design point
Best safety is protected.

Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearer, by the following examples to this
Invention further describes, but protection scope of the present invention is not limited to described embodiment.
Fig. 1 is the schematic diagram of the conventional vehicle front row each major part of automatic seat.
Vehicle occupant restraint systematic function development experiments is by being set under specific position by seat
Complete, as about 25 degree of the inclination angle of backrest 1, seat are arranged on the centre of fore-and-aft direction
Position, waist torr 2 and leg support 4 etc. are packed up, cushion 3 is adjusted to minimum etc..In this case,
Automobile factory is to air bag in car and the major constraints system associated safety such as safety belt and steering column
Part carries out mating and optimizing, thus finally adjusts and meet the passive of regulation even vehicle safety evaluation
Security performance.
But, in sale of automobile to consumer's hand after, due to the individual height of member, body weight,
The differences such as arm length, front-row occupant would generally adjust position before and after seat, the inclination angle of backrest 1,
The parameters such as the height of cushion 3, the parameters value of such seat just with dispatch from the factory before test time parameter
It is worth inconsistent, and major constraints system needs are in parameter value at the trial, could enter occupant
Row maximizes protection, and after occupant changes these parameter values, major constraints system tends not to right
The protection of occupant shows optimum performance.Therefore, currently invention addresses before collision occurs, short
When rapidly the parameters of major constraints system being returned in the time Default Value or tests
Parameter value, thus can provide to front-row occupant when collision occurs and be similar to experimental design state
Good protection.
In view of this, the present invention provides a kind of method of presetting seat before collision occurs, comprising:
Step 101, by collision warning systems or some technical parameters, such as headway, touches
Hitting the time etc. judges whether vehicle frontal collision is inevitable, the most then enter step 102,
If not then continuing to judge；
Step 102, air bag control unit sends regulating command to seat；
Step 103, the seat parameter such as backrest, cushion, waist torr, leg support is adjusted to rapidly dispatch from the factory
Parameter value when setting position or test；
Step 104, the component triggers such as air bag, safety belt provides protection for occupant.
The present invention relates to field of automobile safety, particularly to a kind of side of presetting seat before collision occurs
Method, described method includes: judge whether vehicle frontal collision is inevitable, the most then enter
Next step；Air bag control unit sends regulating command to seat；Seat parameter is adjusted to dispatch from the factory and sets
Location is put.The present invention can actively regulate each major part of automatic seat and arrive before head-on crash occurs
Particular design position, so that major constraints system provides best safety protection for front-row occupant in car.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all
Within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, all
Within protection scope of the present invention should being included in.
