In the description of the present invention, term " center ", " longitudinal direction ", " transverse direction ", "front", "rear", "left", "right", "vertical",
The orientation or positional relationship of the instructions such as "horizontal", "top", "bottom" "inner", "outside" is that orientation based on the figure or position are closed
System, is merely for convenience of description of the present invention and simplification of the description, rather than the device or element of indication or suggestion meaning must have
Specific orientation is constructed and operated in a specific orientation, therefore should not be understood as limiting the scope of the invention.
As shown in Fig. 1 a, Fig. 1 b, Fig. 3 a and Fig. 3 b, the intelligence of drive automatically human posture provided by the present embodiment is driven
Room control method is sailed to include the following steps:
S1 installs the image sensing provided in the first imaging sensor, such as Fig. 1 b on the inside of the car door of driver side
Device 30 is identified by imaging sensor 30 and drives human posture.After in left outside rearview mirror, right outside rear-view mirror and car outside vehicle
Second imaging sensor is installed respectively, such as left outside rearview mirror 31,32 and of right outside rear-view mirror shown in Fig. 1 a and Fig. 1 b on visor
Inside rear-view mirror 33 can identify that the eyes of driver are driving indoor locating position by the imaging sensor on each rearview mirror
It sets.Pressure sensor is installed on the seat, the quantity of pressure sensor is at least three, is separately mounted to seat base, seat
On backrest and headrest, it is respectively used to identify and record to drive the main force part of human body (back B3, buttocks B4 and head B2)
Stress condition.
Demarcate the position of each imaging sensor (including the first imaging sensor and the second imaging sensor).
The first imaging sensor and the second imaging sensor in the present embodiment is using monocular cam, the present embodiment
It is middle using in cameras with fixed focus acquisition driver's cabin, pattern distortion is smaller, therefore ignores tight shot distortion effect, using linear
Model describes camera imaging process.On this basis, first using the prior art (such as bibliography: Zhang Z.A
FlexiBle New Technique for Camera CaliBration. IEEE Transactions on Pattern
Analysis and Machine Intelligence, 2000,22 (11): 1330-1334.) in propose camera internal reference mark
Determine the internal reference that method calibration this patent uses camera, then establishes the coordinate system of vehicle-mounted vision system, and thus design base
In the scaling scheme of vertical chessboard calibration plate.
S2 obtains driver's sample in initialized location using the pressure sensor in S1 and the imaging sensor demarcated
The aspectual character information at moment and be adjusted to corresponding seat attitude data of best sitting posture moment, steering wheel attitude data,
Inside and outside gesture of rearview mirror data and safety belt attitude data.
In S2, the aspectual character information of driver's sample and it is being adjusted to corresponding seat posture number of best sitting posture moment
According to, steering wheel attitude data, inside and outside gesture of rearview mirror data and safety belt attitude data acquisition pattern it is as follows:
As illustratively, driver's sample specifically includes that the height T of driver in Fig. 3 a and Fig. 3 bi, weight Wi.It is marking
After being taken a seat in quasi- driver's cabin, each equipment initialized location moment in driver's cabin, seat attitude data include pedestal rearmost end with
Horizontal guide rail rearmost end spacing Li0=0, the sitting height H of floor in a vehicle to eyessi0, heel to seat base rearmost end horizontal distance
Lfi0, angle β between backrest and seat basei0, at the top of Chain cushion with driver's cabin ground level Hi0, hip joint to vehicle
Height H between interior floorki0.It is being adjusted to best sitting posture moment, seat base rearmost end and horizontal guide rail rearmost end spacing Li,
Sitting height H of the floor in a vehicle to eyessiAnd heel is to seat base rearmost end horizontal distance Lfi, backrest and seat base
Between angle βi, at the top of Chain cushion with driver's cabin ground level Hi, hip joint to height H between floor in a vehicleki0。
Steering wheel attitude data includes the angle of steering lever column and floor in a vehicle, and steering wheel centre is in vehicle axis system
Position.The acquisition of steering wheel attitude data:, can be light according to the initial designs drawing of driver's cabin in driver's cabin reset state
The easily position of acquisition steering lever column and the angle and steering wheel centre of floor in a vehicle in vehicle axis system.Database
Stage records steering wheel pitching motor, steering wheel telescope motor when driver adjusts the suitable position that steering wheel is thought to him
The amount of feeding, and then can convert to obtain current angular and the current location of steering wheel centre of steering lever column and floor in a vehicle.
Inside and outside gesture of rearview mirror data include the mirror surface point of left outside rearview mirror 31, right outside rear-view mirror 32 and inside rear-view mirror 33
Not with the Y in vehicle axis systemVOZVThe angle of plane.Inside and outside gesture of rearview mirror data are respectively Xi、XC1、XC2With YVIt is folded
Acute angle.
Safety belt attitude data is mainly the height of safety belt guide plate, and guide plate adjusts motor control by belt height
System, can by record its amount of feeding calculate safety belt guide plate locating for height, while need record security band tighten-loosen motor
The amount of feeding.
S3, according to S2 obtain driver's sample the initialized location moment aspectual character information and be adjusted to most
Good sitting posture moment corresponding seat attitude data, steering wheel attitude data, inside and outside gesture of rearview mirror data and safety belt posture number
According to establishing database, as shown in table 1.
Table 1 drives personal data collection capacity table
After acquiring N driver's parameters with above-mentioned scale, database is established immediately.Driver's total sample number N need to expire
Sufficient certain amount condition, and the height of driver's sample database, weight distribution curve should meet Chinese driver's somatic data
The height in library, weight distribution trend.
S4 is believed using the aspectual character that the pressure sensor in S1 and the imaging sensor demarcated obtain current driver
Breath, by the obtained current driver of measurement driving in the aspectual character information at initialized location moment and the database purchase of S3
The aspectual character information that proper manners sheet is sailed at the initialized location moment is matched, to search out in the database and current driver
In the immediate driver's sample of the aspectual character information at initialized location moment.That is, the Database is completed
Afterwards, for any one strange driver, its sitting height is measured by the second imaging sensor being mounted on room mirror 33
Hsi0, the imaging sensor that is mounted on car door measure its heel to hip joint horizontal distance Lfi0With the location parameter of each artis
Afterwards, controller will match and the immediate driver's sample of aspectual character of current driver in the database automatically.
S5, the immediate driver's sample searched out according to S4, according to the corresponding data stored in database, adjustment is worked as
Seat posture, steering wheel posture, inside and outside gesture of rearview mirror and the safety belt posture of preceding driver.That is, according to database
Driver's sample of middle storage corresponding relevant parameter when being adjusted to optimum drive sitting posture adjusts the seat of current driver
Attitude data, steering wheel attitude data, inside and outside gesture of rearview mirror data and safety belt attitude data.
Aspectual character information in step S2 and step S4 includes body posture and eye position, in which:
The preparation method of the body posture of driver includes: each pass using the collected driver of the first imaging sensor
Position where node obtains each artis of driver corresponding angle in vehicle axis system, and then obtains driver's
