The invention discloses a left and right wheel positioning method, a tire pressure monitoring chip, a tire pressure monitoring system and a related device. The left and right wheel positioning method comprises the steps: after detecting that a tire rotates, acquiring the duration needed for the tire to rotate by a preset circle; sampling the centrifugal acceleration and the tangential acceleration of the tire within the duration; determining a lead-lag relationship between the centrifugal acceleration and the tangential acceleration of the tire based on the sizes of the sampling point serial numbers corresponding to the sampled centrifugal acceleration and the sampled tangential acceleration respectively; and determining whether the tire is a left wheel or a right wheel based on the lead-lag relationship between the centrifugal acceleration and the tangential acceleration of the tire. According to the scheme, the tire can be positioned through the low-precision acceleration sensor.

    本申请公开了一种左右轮定位方法、轮胎压力监测芯片及系统、相关装置,其中,该左右轮定位方法包括:在检测到轮胎转动后,获取所述轮胎转动预设圈所需的时长;在所述时长内对所述轮胎的离心加速度和切向加速度进行采样;基于采样的所述离心加速度和切向加速度分别对应的采样点序号的大小,确定所述轮胎的离心加速度与切向加速度之间的超前滞后关系;基于所述轮胎的离心加速度与切向加速度之间的超前滞后关系,确定所述轮胎为左轮或右轮。上述方案,能够通过较低精度的加速度传感器实现对轮胎的定位。
