TIRE PATCH DETECTION

The invention discloses tire patch detection. A detection system for extracting information from a sensor module in a rolling wheel. The detection system comprises: a sensor module which comprises a sensor adapted for sensing a physical property of the tire when mounted in a tire of the wheel or on an inner surface of a tire of the wheel; an acquisition module adapted for sampling a signal from the sensor module, thus obtaining a sequence of data samples; a correlation module adapted for cross-correlating a signed reference sequence with the sequence of data samples thus obtaining a correlation sequence; an extraction module adapted for identifying at least one perturbation in the correlation sequence, wherein the perturbation is induced when a part of the tire where the sensor is mountedhits the ground thereby forming the tire patch. 本申请公开了轮胎印迹检测。用于从滚动车轮中的传感器模块提取信息的检测系统。该检测系统包括：传感器模块，该传感器模块包括适于在被安装在车轮的轮胎中或被安装在车轮的轮胎的内表面上时感测轮胎的物理属性的传感器；采集模块，该采集模块适于对来自传感器模块的信号进行采样，从而获得数据样本序列；相关性模块，该相关性模块适于将有符号参考序列与数据样本序列进行互相关，从
