With 0, wherein 1 representing positive class, 0 represents negative class.Such as, n=5, classification corresponds to 1,2,3,4,5 respectively, tire pressure value correspondence respectively
It is 1.0,1.5,2.0,2.5,3.0；By many classification problems being converted into multiple two classification problems, set up multiple two classification moulds
Type, such as some two disaggregated model are used to distinguish classification 1 and classification 2, and another two disaggregated model is used to region class
Other 1 and classification 3, another is used to distinguish classification 1 and classification 4, by that analogy, then the classification submodel set up.
Further, described modeling unit is based on the described tire pressure disaggregated model built, it is thus achieved that have obvious classification effect
Characteristic attribute, based on described characteristic attribute, described characteristic attribute is carried out preset processing mode (such as Logic Regression Models) enter
Row processes, it is thus achieved that under multiple dimensions (i.e. acceleration, angular velocity and direction), processes by above-mentioned processing mode and obtains different tire pressure
The threshold value of value correspondence or threshold range；Wherein, there is a numerical range, by institute owing to tire pressure is in tire pressure value under normal condition
State threshold value corresponding to the tire pressure value beyond numerical range or threshold range writes described abnormal tire pressure characteristic range.Based on this, build
Model that form unit is set up as above-mentioned processing mode and model combination and data processing method form the tire described in the present embodiment
Pressure prediction model.
Certainly, the embodiment of the present invention is not limited to use disaggregated model to process, it is also possible to carried out by regression model
Processing, the concrete processing procedure using regression model can refer to, described in prior art, be not described in detail in the present embodiment.
In the present embodiment, during tire pressure monitoring, described detector unit gets vehicle from described data acquisition unit
Behavioral data, and the state characteristic information (including velocity information and/or the positional information of vehicle) of described vehicle, by above-mentioned
The tire pressure forecast model that modeling unit is set up is analyzed processing, it is thus achieved that corresponding numerical value；Or adopt in preset time period
