Abstract

A code learning method for a tire monitoring device installed in a vehicle comprising a front left tire, a front right tire, a rear left tire, and a rear right tire, comprising the following steps of: providing a plurality of sensor modules installed in the tires of the vehicle for sensing condition and acceleration of the tires and each having an identifying code and a radio transmitter for transmitting signals including the condition of the tire, the acceleration of the tire, and the identifying code of the sensor module; inflating the front tires and the rear tires with different pressures, respectively; receiving the signals for identifying the signals transmitted from the sensor modules installed in the front tires or the rear tires by the order of the pressures in the signals; and driving the vehicle and receiving the signals for identifying the signals transmitted from the sensor modules installed in the left tires or the right tires by the acceleration in the signals.

Claims

1. A code learning method for a tire monitoring device installed in a vehicle comprising a front left tire, a front right tire, a rear left tire, and a rear right tire, comprising the following steps of:

providing a plurality of sensor modules installed in the tires of the vehicle for sensing condition and acceleration of the tires and each having an identifying code and a radio transmitter for transmitting signals including the condition of the tire, the acceleration of the tire, and the identifying code of the sensor module;

inflating the front tires and the rear tires with different pressures, respectively;

receiving the signals and, by means of the order of the pressures in the signals, identifying the signals transmitted from the sensor modules installed in the front tires or the rear tires; and

driving the vehicle, receiving the signals and, by the acceleration in the signals, identifying the signals transmitted from the sensor modules installed in the left tires or the right tires.

2. The code learning method according to claim 1, wherein the vehicle further comprises a spare tire and the code learning method further comprises the steps of:

providing a sensor module installed in the spare tire of the vehicle for sensing condition and acceleration of the spare tire and having an identifying code and a radio transmitter for transmitting signals including the condition of the tire, the acceleration of the tire, and the identifying code of the sensor module; and

driving the vehicle, receiving the signals and, by means of the acceleration in the signals, identifying the signals transmitted for the sensor module installed in the spare tire.

3. The code learning method according to claim 1, wherein the signals are radio frequency signals.

4. The code learning method according to claim 1, wherein the condition of the tire is selected from the group consisting of pressure, temperature, and the combination thereof.

6. The code learning method according to claim 1, wherein the signals are radio frequency signals.

7. The code learning method according to claim 1, wherein the condition of the tire is selected from the group consisting of pressure, temperature, and the combination thereof.

5. A code learning method for a tire monitoring device installed in a vehicle comprising a plurality of tires, comprising the following steps of:

providing a plurality of sensor modules installed in the tires of the vehicle for sensing condition of the tires and each having an identifying code and a radio transmitter for transmitting signals including the condition of the tire and the identifying code of the sensor module;

inflating the plurality of tires of the vehicle with pressure in a predetermined order according to the positions of the tires; and

receiving the signals and, by the order of the pressures in the signals, identifying the positions and the identifying codes of the sensor modules transmitting the signals.
