The invention provides an automobile tire pressure monitoring method and system based on multi-sensor fusion, and the method comprises the steps: obtaining the temperature, pressure and vibration parameters of a working environment of a sensor module, building a multiple regression analysis model with the temperature, pressure and vibration as independent variables and the sensor output precision as a dependent variable, and obtaining a sensor performance degradation mathematical model; for deformation and vibration interference in the high-speed running process of a tire, a self-adaptive noise elimination algorithm based on the minimum mean square error criterion is adopted, preprocessing such as filtering and smoothing is carried out on original data of a sensor, and the signal-to-noise ratio and stability of the data are improved; a general data analysis module is designed for data formats and protocol differences of different types of sensors, automatic identification and conversion of heterogeneous sensor data are achieved by configuring a sensor data format template, and the data are mapped to a unified data model.

    本发明提供一种基于多传感器融合的汽车胎压监控方法与系统,包括:获取传感器模块工作环境的温度、压力、振动参数,建立以温度、压力、振动为自变量,传感器输出精度为因变量的多元回归分析模型,得到传感器性能退化数学模型;针对轮胎高速行驶过程中的形变和振动干扰,采用基于最小均方误差准则的自适应噪声消除算法,对传感器原始数据进行滤波、平滑等预处理,提高数据信噪比和稳定性;针对不同类型传感器的数据格式和协议差异,设计通用数据解析模块,通过配置传感器数据格式模板,实现异构传感器数据的自动识别和转换,将数据映射到统一数据模型。
