Two, static check, calibrator (-ter) unit are mounted on position on automobile；Automobile is parked on horizontal road surface, and acquisition is current to be added
Speed counts the conversion method for obtaining equipment Installation posture Yu automobile XYZ axis, and the XYZ number of axle evidence of equipment is converted to automobile water
On flat coordinate, gravity axis is found out；
Three, dynamic check judges vehicle traveling direction and XYZ axis direction relationship；The movement for filtering reversing automobile, is adopted
Collect the data of gyroscope and accelerometer, while guaranteeing the certain speed of automobile, obtains vehicle traveling direction and XYZ axis direction relationship；
Four, after verification, show that automobile emergency accelerates, anxious to slow down, the travelings movement such as zig zag.
Preferably, finding out the judgment method of gravity axis in step 2 are as follows: if which axis reading in tri- axis of XYZ
Data close to 1G, this axis be exactly gravity axis, other two axis just in the horizontal plane, other two axis and automobile reference coordinate
It is obtained by automobile positive traveling.
Preferably, if can not find gravity axis, equipment is installed after rotation in step 2, pass through reading
Data find out rotary shaft, and rotary shaft data are converted close to 0 by coordinate, obtain device coordinate and automobile coordinate relationship.

For the number of axle according to judging, which is vehicle traveling direction axis, the direction of axis and garage positive relationship.
The present invention provides one kind to be based on six axle sensor equipment Installation posture calibration methods, being capable of preferably posture school
Standard, so that the automobile of different automobile types, which can easily install running car behavior, judges system.
Specific embodiment
To further appreciate that the contents of the present invention, the present invention is described in detail in conjunction with the embodiments.It should be understood that
Embodiment be only to the present invention explain and and it is non-limiting.
Embodiment 1
It present embodiments provides a kind of based on six axle sensor equipment Installation posture calibration methods comprising following steps:
One, sensor readings are opened；
Two, static check, calibrator (-ter) unit are mounted on position on automobile；Automobile is parked on horizontal road surface, and acquisition is current to be added
Speed counts the conversion method for obtaining equipment Installation posture Yu automobile XYZ axis, and the XYZ number of axle evidence of equipment is converted to automobile water
On flat coordinate, gravity axis is found out；
Three, dynamic check judges vehicle traveling direction and XYZ axis direction relationship；The movement for filtering reversing automobile, is adopted
Collect the data of gyroscope and accelerometer, while guaranteeing the certain speed of automobile, obtains vehicle traveling direction and XYZ axis direction relationship；
Four, after verification, show that automobile emergency accelerates, anxious to slow down, the travelings movement such as zig zag.
In the present embodiment, in step 2, equipment is installed to car, is not necessarily Z axis and horizontal plane, it is also possible to
Be X-axis or Y-axis, find out the judgment method of gravity axis are as follows: if the data which axis is read in tri- axis of XYZ close to 1G, this
Axis is exactly gravity axis, and just in the horizontal plane, other two axis and automobile reference coordinate are travelled other two axis by automobile positive
It obtains.
In the present embodiment, in step 2, if can not find gravity axis, equipment is installed after rotation, passes through reading
Access evidence, finds out rotary shaft, rotary shaft data are converted close to 0 by coordinate, obtain device coordinate and automobile coordinate relationship.
In the present embodiment, coordinate conversion is column matrix to be turned in the profound matrix more than direction that is projected through of a certain reference frame
Change to the process on another coordinate system.Such as:
R1=Cr2；
Wherein, C be a column matrix is transformed into vehicle level coordinate system 1 from carrier coordinate system 2 direction more than profound square
Battle array.
If remaining profound direction matrix C is available around Z rotational angle β:
Then obtain:
R1={ x2cos β-y2sin β, x2sin β+y2cos β, z2 }；
Because automobile is off in the horizontal plane, then { 0,0, g } r1=at this time, r2 is read by sensing data, can be solved
Cos β and sin β out, while obtaining remaining profound direction matrix C；
If around other axis rotation also similar calculating.
In the present embodiment, in step 3, device coordinate system and vehicle axis system relationship have been known by two step of front,
But also one is exactly that coordinate conversion rear direction is not necessarily the same with driving direction, so to come in automobile normal running
Judgement.First pass through read automobile RPM or GPS speed, when running car be greater than 20Km/h, 100 groups of accelerometers of continuous acquisition and
The data of gyroscope, gyro data guarantee automobile straight-line travelling, are judged by accelerometer X and Y-axis data, which is vapour
Vehicle travels axis of orientation, the direction of axis and garage's positive relationship.
Equipment Installation posture can be obtained by static check and dynamic check, remaining profound direction matrix is found out, sensing
On device data transmission vehicle axis system, so that it may calculate vehicle driving state.Above schematically to the present invention and its embodiment party
Formula is described, and description is not limiting.So not departed from if those of ordinary skill in the art are inspired by it
In the case where the invention objective, frame mode similar with the technical solution and implementation are not inventively designed
Example, is within the scope of protection of the invention.
