The invention provides an automatic tire positioning system for automobile tire pressure monitoring. The automatic tire positioning system comprises a processor U1, four tire pressure sensor assemblies U2 and a rotation position detection unit U3. The processor U1 calculates a sensor ID (Identity) corresponding to each tire according to the corresponding relationship between an acceleration characteristic curve and a rotation position tooth number under the same tire through tire acceleration information monitored by the four tire pressure sensor assemblies U2 and tooth number information of the rotation position detection unit U3; and the ID information obtained through calculation is compared with the tire pressure ID information stored in the processor U1, and the ID information which needs to be reserved finally is determined according to the comparison result. After the ID of the tire pressure system is wrong, the ID can be automatically calibrated in the driving process, and the requirement for the computing power of the central processing unit U1 in the calibration process is low.
本发明提出一种汽车胎压监测的轮胎自动定位系统,包括处理器U1、四个胎压传感器总成U2和旋转位置检测单元U3。所述处理器U1通过四个胎压传感器总成U2监测的轮胎加速度信息和旋转位置检测单元U3的齿数信息,根据同一轮胎下加速度特性曲线与旋转位置齿数的对应关系,计算出每个轮胎所对应的传感器ID,并将计算得出ID信息与处理器U1存储的胎压ID信息进行对比,根据对比结果,确定最终应保留的ID信息。本发明在胎压系统ID错误后能够在行驶过程中自动校准ID,且校准过程对中央处理U1的算力要求比较低。
