Description
Technical field
The invention belongs to passenger protection field in safety device for motor vehicle, particularly to one in rear-end impact, protection
The motor vehicle intelligent safety seat of occupant's cervical region safety and control method thereof.
Background technology
Automobile seat is rested the head in addition to providing preferable riding comfort for occupant, and its prior effect is for occupant
Head provides and relies on the most spacing.
In Motor vehicle rear-end crash, adult occupants's upper body is moved rearwards by because of collision inertia force effect.If in the process,
Chair headrest relative to adult occupants's head locus in the horizontal direction, on vertical direction the best, the most in the horizontal direction
On, when occupant's back of head and the horizontal range rested the head between front surface are bigger；Or in the vertical direction, the occupant crown is beyond on headrest
During surface；Occupant's head rearward displacement amount can be caused more than chest rearward displacement amount, it is easy to cause cervical region " to whip " injury.
At present for reducing in rear-end impact, adult occupants's cervical region " whips " injury, and the automobile safety of Lear Compzny grinds
The person of studying carefully proposes the concept of SAHR: 1) when rear-end impact occurs, and occupant's upper body is moved back by because of collision inertia force effect
Dynamic, this headrest can utilize occupant's back, the waist pressure to backrest, and forward upward moves, and shortens occupant's back of head and headrest
Horizontal range between front surface, quickly holds head, reduces head back displacement；Increase height of headrest simultaneously, finally reduce
Cervical region " whips " injury.2) after rear-end impact terminates, SAHR automatically resets.Although SAHR can be necessarily
In degree protect occupant's cervical region, but still have the disadvantage that (1) when rear-end impact occurs, SAHR is gone up the most forward
Fang Yundong, delay of response, the best to the protected effect of occupant's cervical region；(2) stroke of SAHR forward upward motion is limited,
If before rear-end impact occurs, the horizontal range between occupant's back of head and headrest front surface is very big, or the occupant crown far beyond
During headrest upper surface, the protected effect of occupant's cervical region can be significantly reduced by SAHR.
Being similarly and reduce in rear-end impact, adult occupants's cervical region " whips " injury, and Volvo Aktiebolaget is proposed
WHIPS incidence protecting chair: when rear-end impact occurs, the backrest of this seat is first along with occupant's rearward movement, then turns round
Dynamic certain angle, thus buffer the collision impulsive force to occupant's cervical region, significantly reduce cervical region and " whip " injury.But WHIPS head
The shortcoming of neck protection seat is: can not automatically reset after deformation.
IIWPG (international insurance association cervical injuries prevention group) gives relative adult occupants's head space position of resting the head on
Safety evaluatio standard, is used for evaluating headrest and avoids adult occupants's cervical region " to whip " ability injured.This standard is pointed out: when at water
Square upwards, the horizontal range between headrest front surface and adult occupants's back of head is less than or equal to 4cm；Simultaneously at vertical direction
On, when headrest upper surface is beyond the adult occupants crown, it is " outstanding " grade that headrest avoids cervical region " to whip " ability injured, can
It is prevented effectively from cervical region and " whips " injury.
Summary of the invention
For solving the deficiency that above-mentioned SAHR and WHIPS incidence protecting chair exist, make the headrest can be effective simultaneously
Avoid adult occupants's cervical region " to whip " injury, the invention provides a kind of motor vehicle intelligent safety seat and control method thereof.This

(1) driving sensor is according to vehicle wheel rotation, it is judged that whether motor vehicles starts running, if motor vehicles starts running, OK
Running signal is sent to ECU by car sensor；Medicated cushion pressure transducer measures occupant's pressure to medicated cushion, and is sent to ECU,
According to force value, ECU judges whether occupant is adult occupants；When ECU obtains running signal, and confirm when occupant is adult occupants,
Determine that motor vehicle intelligent safety seat is started working.
(2) after motor-driven vehicle going, inclination of the seat backrest sensor measures backrest transverse center face and medicated cushion transverse center in real time
Included angle A 1 between face, headrest obliquity sensor measures headrest front surface and the motor vehicles included angle A 2 that moves forward between direction in real time,
And A1, A2 are sent to ECU.When A1 is between 70 degree to 140 degree (i.e. 70 degree ＜ A1 ＜ 140 degree), when A2 is acute angle simultaneously,
ECU starts servomotor, and the output shaft of servomotor makes headrest rotate backward around its transverse central axis, finally makes A2 become straight
Angle；When A1 is between 70 degree to 140 degree, when A2 is obtuse angle simultaneously, ECU starts servomotor, and the output shaft of servomotor makes
Headrest rotates forward around its transverse central axis, finally makes A2 become right angle；When A1 is between 70 degree to 140 degree, and A2 is former simultaneously
When this is just for right angle, ECU does not start servomotor, and A2 keeps constant.In addition when A1≤70 degree, or during A1 >=140 degree, ECU is not

The intelligent control method of described safety seat includes the following:
After motor vehicles starts running, running signal is sent to ECU7 by driving sensor 12, and ECU7 is according to medicated cushion simultaneously
Pressure transducer 11 measures the occupant the obtained force value to medicated cushion, it is judged that whether occupant is adult occupants.Travel when ECU obtains
Signal, and confirm when occupant is adult occupants, ECU7 makes the decision starting safety seat for motor vehicle.
ECU7 starts inclination of the seat backrest sensor 10 and headrest obliquity sensor 5, and inclination of the seat backrest sensor 10 is measured in real time and leaned on
Carrying on the back the included angle A 1 (as shown in Figure 2) between 8 transverse center faces and medicated cushion 9 transverse center face, headrest obliquity sensor 5 measures head in real time
Rest the head on 1 front surface and included angle A 2 that motor vehicles moves forward between direction, and A1, A2 are sent to ECU7.
Generally, in motor vehicles normally travels, the A1 of pilot set is all in (i.e. 70 degree ＜ between 70 degree to 140 degree
A1 ＜ 140 degree), now it is normally carried out following steps；For the passenger seat of other positions, as 70 degree of ＜ A1 ＜ 140 degree, take advantage of
Visiting chair is in normal condition, is now normally carried out following steps, when A1≤70 degree, passenger seat be in improper " from
Position " state, now terminate following steps, when A1 >=140 degree, passenger is in lying position, and now cervical region has obtained preferably
Protection, the most also terminates following steps, and i.e. when A1≤70 degree, or during A1 >=140 degree, ECU terminates running safety seat for motor vehicle.
When A1 is between 70 degree to 140 degree, when A2 is acute angle simultaneously, ECU7 starts servomotor 6, servomotor 6
Output shaft makes headrest 1 rotate backward around its transverse central axis, finally makes A2 become right angle；When A1 is between 70 degree to 140 degree,
When A2 is obtuse angle simultaneously, ECU7 starts servomotor 6, and the output shaft of servomotor 6 makes headrest 1 around its transverse central axis forwards
Dynamic, finally make A2 become right angle；When A1 is between 70 degree to 140 degree, when A2 is originally just for right angle simultaneously, ECU7 does not start and watches
Taking motor 6, A2 keeps constant.
When A1 is between 70 degree to 140 degree, A2 is that (i.e. rest the head on 1 front surface and the motor vehicles side of moving forward at right angle simultaneously
To vertically, 1 upper surface of the resting the head on direction that moves forward with motor vehicles is parallel) time, ECU7 first starts infrared detector 4.Infrared ray
After detector 4 starts, the real-time forward horizontal of infrared emitting mouth 40 of infrared detector 4 launches infrared ray, at infrared ray
In the linear extent of emission port 40 horizontal front 20cm, infrared detector 4 is detectable to be gone out to block with or without object.Because infrared ray is sent out
Loophole 40 is positioned at headrest 1 front surface top edge midpoint, it is generally the case that straight at infrared emitting mouth 40 horizontal front 20cm
In the range of line, only can there is " head of adult occupants 2 " this kind of object.When infrared detector 4 is detected with adult occupants 2
Head block, i.e. in the vertical direction, the crown of adult occupants 2 beyond headrest 1 upper surface time, ECU7 starts servomotor 6,
The output shaft of servomotor 6 makes headrest 1 the most vertically move, in headrest 1 upwards vertical moving process, and infrared detector 4
Real-time detection is blocked with or without object, if headrest 1 upper surface is beyond the crown of adult occupants 2, then infrared detector 4 detects
Head without adult occupants 2 blocks, and now ECU7 closes servomotor 6, and headrest 1 the most vertically moves；When infrared ray is visited
Surveying device 4 to detect and originally block without object, when 1 upper surface script of i.e. resting the head on is the most just beyond the crown of adult occupants 2, ECU7 does not opens
Dynamic servomotor 6, does not change the position of headrest 1.
When A1 is between 70 degree to 140 degree, A2 is that (i.e. rest the head on 1 front surface and the motor vehicles side of moving forward at right angle simultaneously
To vertical), and headrest 1 upper surface beyond the crown of adult occupants 2 time, ECU7 restarts radar range finder 3.Radar range finder
After 3 start, the radar emission mouth 30 of radar range finder 3 launches forward radar wave in real time, thus radar range finder 3 can be surveyed in real time
Horizontal range S between amount headrest 1 front surface and adult occupants 2 back of head, and this horizontal range S is sent to ECU7.When S is more than
During 4cm, ECU7 starts servomotor 6, and the output shaft of servomotor 6 makes headrest 1 forward horizontal move, at headrest 1 forward horizontal
In moving process, S measured in real time by radar range finder 3, if S has foreshortened to 4cm, then ECU7 closes servomotor 6, and headrest 1 is no longer
Forward horizontal moves so that S is maintained at 4cm；When S is less than 4cm, ECU7 starts servomotor 6, the output shaft of servomotor 6
Making headrest 1 move horizontally backward, during headrest 1 moves horizontally backward, S measured in real time by radar range finder 3, if S increases
To 4cm, then ECU7 closes servomotor 6, and headrest 1 moves horizontally the most backward so that S is maintained at 4cm；When S is originally just for 4cm
Time, ECU7 does not start servomotor 6, does not change the position of headrest 1.
To sum up, safety seat for motor vehicle intelligent control method of the present invention is utilized, by safety seat for motor vehicle
ECU7, various sensor, radar range finder 3, infrared detector 4 and the synergism of servomotor 6, first in vertically side
