Tire positioning method and tire positioning system

摘要

A tire positioning method includes the following steps. Four wireless signals transmitted from four tires of a car are received by a wireless signal receiver. Each wireless signal includes a uniaxial acceleration. One of the tires which is located at a first location is identified according to the intensity of the wireless signals. The first location is the closest to the wireless signal receiver. When the car makes a turn, one of the tires which is located at a second location is identified according to the direction of each uniaxial acceleration. The second location and the first location are both located at one side of the car. The direction of the uniaxial acceleration of the tire which is located at the first location is identical to that of the tire which is at the second location. The side of the car is right side or left side.

1. A tire positioning method, comprising:
receiving four wireless signals transmitted by four tires of a vehicle by a wireless signal receiver, wherein each of the wireless signals comprises only a uniaxial acceleration; identifying a tire of the tires at a first position according to the intensity of the wireless signals, wherein the tire at the first position is closest to the wireless signal receiver; and identifying a tire of the tires at a second position according to the positive direction of the uniaxial accelerations when the vehicle make a turn, wherein the first position and the second position are both at the left side of the vehicle or both at the right side of the vehicle; wherein the positive direction of uniaxial acceleration of the tire at the first position is identical to the positive direction of uniaxial acceleration of the tire at the second position.
