确定轮胎安装位置的方法、轮胎压力监测装置和系统
摘要：
公开了一种确定轮胎安装位置的方法、轮胎压力监测装置和系统，本发明的技术方案在轮胎内设置双轴磁传感器，至少测量轮胎周向或轴向上的磁场强度和与径向上的磁场强度。利用轮胎安装在左侧和右侧时，磁传感器在周向或轴向上的切割外界磁场的方向相反、而在与径向上切割外界磁场的方向相同的特点，通过不同方向上磁场强度采样值的差值变化趋势可以判断轮胎安装于左侧还是右侧。由此，允许在以较低的采样率来获取磁场强度的前提下，仍能够将不同侧的轮胎进行区分。可以有效降低系统功耗，提高电池使用寿命。
摘要（英）：

Determining installation positions of tires can include: measuring, by a magnetic sensor provided in each tire in the same manner, a first magnetic field strength in a first direction and a second magnetic field strength in a second direction, where the first direction is a circumferential or axial direction of the tire and the second direction is a radial direction of the tire; acquiring a first magnetic field strength sampling value of the tire by sampling the first magnetic field strength; acquiring a second magnetic field strength sampling value of the tire by sampling the second magnetic field strength; calculating a difference between the first and second magnetic field strength sampling values; and determining whether the installation position of the tire is on the left or right side of a vehicle according to a change trend of the calculated difference of the tire.
