Embodiment 1
As shown in figure 1, the embodiment of the present invention proposes a kind of method for disturbing judgement and data processing, applied to automotive wheels
Tire status monitoring, including：
S101, obtain caused multivariate data during unit mileage vehicles traveling.
Obtain caused multivariate data during unit mileage vehicles traveling can the acquisition wrapped of subdivision one or
Obtained after the collection of one cell data of completion by the way of first in first out.
The multivariate data includes：Tire pulse data, tire radius, tire rotational speed, brake opening degree, throttle folding
Degree, steering wheel angle.
S102, judge whether be interfered in vehicle travel process.
It is interfered and specifically includes in the vehicle travel process：
Throttle opening degree rate of change is more than preset value, brake opening degree rate of change is more than preset value, steering wheel angle is more than in advance
If value；
The difference of the pulse data of coaxial tire is more than preset value, coaxial wheels more than the difference of preset value, the radius of coaxial tire
The difference of the rotating speed of tire is more than preset value；
The difference of the summation pulse data of coaxial tire is more than more than the difference of preset value, the summation pulse data of diagonal tire
Preset value；
The difference of the pulse data rate of change of coaxial tire is more than more than the difference of preset value, the rate of change of angular of coaxial tire
Preset value.
S103, when being interfered, interference processing is carried out to the multivariate data.
Interference processing is carried out to the multivariate data to specifically include：Filtering, replace and fill.
Filtering is specially to filter a packet, supplements a packet, ensures to occur without switch in analysis mileage unit.
Replace for there is discontinuous interference non-equilibrium state, abnormal number caused by indivedual interference is replaced with normal value
According to.
Fill for occurring continuously disturbing non-equilibrium state, be only used for monitoring pattern, occur to fast reaction tire
Final state during problem.
By the calculating between mode of learning or similar mode, and tyre revolution speed difference, come reach amendment tire that
Error between this, either value is contrasted or in the stage of tabling look-up as amendment foundation as variable quantity in the monitoring stage, to improve
Monitoring and the method for monitoring precision.
Using from going small examination principle to determine the original differences between coaxial or 4 tires as the corrigenda greatly
Value.
With mode of learning Recognition Different and interference, and data class predication method, data are replaced or the side of integrated application
Formula, the processing method of data is disturbed tire.
Judged by the elementary error between learning process amendment tire, and to interference.
By mode of learning, using the minimum mileage measurement unit of one or more automobile as unit of analysis, to vehicle just
Often caused multiple parameters are acquired and analyzed during traveling, and filter out and may cause coaxial or 4 tyre revolutions
The inconsistent interference data of speed, according to the approximately equalised interpretation criterion of diagonal tire ABS pulse data sums, respectively analysis and
In the case of accumulation calculating relative equilibrium (normal) and uneven (improper), the ABS pulse accumulation numbers of tetra- tires of A, B, C, D
According to, and data statistics is carried out to relative equilibrium and non-equilibrium state occurs, according to from removing small discriminating method greatly, so that it is determined that with
The data source of original differences between 4 tires are calculated, and with this corrigenda value between calculating, judge and eliminate tire
Initial error.
The calculating of corrigenda value, the amendment of corrigenda value and ABS pulse data bags, all it is to be carried out with " bag " for unit, only
It could so facilitate and compare, replace, fill and correct, one " bag " is referred to the minimum odometer of one or more automobile
It is the ABS pulse datas in unit of analysis to measure unit.
Under monitoring pattern, data processing method during for being disturbed influence can also, filtered in a manner of whole bag, mistake
A bag is filtered, supplement one is wrapped, and is also not in the phenomenon of switch；Meanwhile to the receive process of ABS pulse datas, complete the
After one monitoring cycle, the data acquisition of next cycle from the beginning is not required to again, the side of " first in first out " can be taken
Formula, with the packet backmost come in, squeeze out it is most advanced come packet, both can be with using such packet recursion mode
Ensure that analysis mileage unit is consistent, can more further speed up the reaction speed of monitoring.
Monitoring pattern is tabled look-up as tire pressure value with to mark the metering mileage unit of time set and tire condition monitoring, analysis and
Metering cycle, using each all metadata collected from automobile bus, and according to the corrigenda value obtained under mode of learning, to 4
The ABS pulse datas of individual tire are corrected and added up respectively accordingly.If there is discontinuous unbalance condition during this
Occur, according to amendment back coaxial wheel tire and the approximately equalised equilibrium principle of diagonal tire ABS pulse data sums, maintenance data
Class predication method directly replaces abnormal data caused by interference, and to ensure within the monitoring mileage cycle, ABS pulse datas are not in
Switch phenomenon；If Chang continuously occurs the unbalanced extreme situation of n times during this, preserve and cumulative amendment corrigenda during this period
ABS actual pulse data after value, and on the basis of this data, maintenance data class predication method, calculate and fill in whole monitoring
ABS pulse accumulation data in the journey cycle, with the state change of real-time response tire.
