For cornering ratio measured value；
S4: cornering ratio measured value obtains cornering ratio measured value and standard is horizontal compared with standard lateral force coefficient
To the measurement error of force coefficient；
S5: adjustment cornering ratio test macro repeats step S3 and S4, until cornering ratio measured value and standard are horizontal
To force coefficient measurement error in defined error range.
In the prior art, calibration system only the individual part to cornering ratio test macro in laboratory carry out calibrating or
Person's calibration, and be only capable of reflecting the equipment measured value situation under static simulation state, live whole equipment can not be measured,
Thus it can not reflect the accuracy of dynamic measurement results of the whole equipment under normal driving states, to keep measured value inaccurate
Really.In the metering method of the application, the standard lateral of multiple and different standard components is measured using standard lateral force coefficient test macro 3
Force coefficient, obtained standard lateral force coefficient precision is high, as the standard of judge, evaluates subsequent cornering ratio,
So that the cornering ratio test macro of calibration also has relatively higher precision；Intermediary of the standard component as calibration,
Precision influences the stated accuracy of cornering ratio test macro, and the standard component that completion is measured in the application is laid with road surface on site,
Enough spaces are provided for lateral force test system dynamic measurement to be calibrated, cornering ratio test macro dynamic to be calibrated passes through

Time and manpower reduce expense expenditure, while ensure that the precision of cornering ratio test macro to be calibrated, so that cross to be calibrated
Precision to force coefficient test macro is high, meets measurement request.
More specifically, step S1 is specifically included:
S101: standard component is layed in conveyer belt 7, and the testing wheel of standard lateral force coefficient test macro 3 is placed on standard component；
S102: load measurement module 5 is placed in below the testing wheel of standard lateral force coefficient test macro 3, and adjustment criteria is horizontal
To the counterweight of 3 testing wheel of force coefficient test macro, so that the load that load measurement module 5 measures is standard load；
S103: adjusting the water supply of environment temperature, the linear velocity of conveyer belt 7 and water supply module 4, so that these parameters and mark
The parameter for determining environment is consistent；
S104: the standard lateral force coefficient of standard component is measured using standard lateral force coefficient test macro 3；
S105: repeating above step, completes the standard lateral force coefficient measurement of multiple and different horizontal antiskid performance standard components.
Above-mentioned steps guarantee that the determination of the environment of standard component is standard, that is, load, temperature, linear velocity, water supply etc.
All environmental factors are all to be manually set, and on the one hand guarantee that the performance of standard component is stablized, will not cause surface sliding because of environmental change
Dynamic performance changes, and on the other hand, is only measured in the case where environmental factor is with calibration state consistency, obtained
Measured value is only standard, this standard value just has comparativity, if environment is variation, the standard of the standard component measured
Value is also not standard, has no idea to carry out subsequent calibration, even if carrying out subsequent calibrations, obtained calibration result is also not smart
True.
It is understood that increase the accuracy of measurement result, the quantity selection of standard component no less than four, to multiple
Standard component is measured, and when the larger situation of measurement error occurs in one of standard component, other standard components can mutually be should be used as
With reference to, to calibration personnel provide foundation.
And, it is preferred that the standard lateral force coefficient measurement of same standard component should be repeated five times at least in step S104,
In five groups of obtained data, remove maximum value and minimum value, it is to be understood that repeatedly measurement can reduce measurement error, maximum
The error of value and minimum value is maximum, removes maximum value and minimum value, takes the average value of remaining three groups of data, as standard lateral power
Coefficient improves the accuracy of measurement in this way.
More specifically, in step S2, the laying length of standard component is not less than the survey of standard lateral force coefficient test macro 3
Twice of examination wheel perimeter.It is understood that since cornering ratio test macro to be calibrated in step S3 is dynamic by mark
Quasi- part, if the length that standard component is laid with is too short, cornering ratio test macro to be calibrated is likely to unstable in traveling
Or pass through standard component in the case where offsetting, at this time measurement error is big, causes to cornering ratio test macro to be calibrated
Measurement result inaccuracy, cannot be according to cornering ratio test macro to be calibrated be adjusted with the measurement result.
In embodiments herein, step S3 is specifically included:
S301: adjusting the speed of cornering ratio test macro to be calibrated, guarantees that speed is at the uniform velocity；
S302: the testing wheel uniform rectilinear of cornering ratio test macro to be calibrated crosses standard component, obtains cross force system
Number measured value；
S303: above step is repeated, multiple groups cornering ratio measured value is obtained, is averaged, as the cross of the standard component
To force coefficient measured value.
When due to cornering ratio test macro driving status difference to be calibrated, obtained measured value is different, therefore to protect
The accuracy of measurement result is demonstrate,proved, cornering ratio test macro to be calibrated is in the driving status of uniform rectilinear, and guarantees each
Travel speed it is identical so that each measured value can remove the big measured value of error, improve systematic survey mutually as reference
Accuracy.
According to an embodiment of the present application, cornering ratio measured value obtains compared with standard lateral force coefficient in step S4
The measurement error of cornering ratio measured value and standard lateral force coefficient, since standard component has multiple, measured errors also will
Have multiple, multiple measurement errors can be actually maximized as final error, the as reference error of system calibrating.
