Abstract

The present invention disclosed herein is a tire pressure monitoring system (TPMS) with a time encoded wireless tire condition sensing device and warning signal, wherein each transmitter ID is assigned its own timing parameter through the controlling device wherein each timing parameter has a different time delay to prevent any launch time transmission overlap. Furthermore, when the main controller receives data from a transmitter indicating abnormal tire condition, the vehicle velocity information is recorded and vibration detection is activated to determine whether there is abnormal vibration and, therefore, whether to transmit vibration warning signal to the display unit and/or to the mobile device of the driver.

Claims

1. A method for monitoring tire pressure comprising

a. providing a main controller wherein said main controller is comprised of a second micro-processing unit, a second memory unit, a first receiver unit, a display unit, an operating unit, a control switch, a second transmitter unit, and a master wireless transceiver unit;

b. providing one or more tire transmitter wherein said tire transmitter is comprised of a first micro-processing unit, a first memory unit, a second receiver unit, a first transmitter unit, a second receiver unit, and a first detection unit;

c. having said first micro-processing unit transmit a pairing signal via said first transmitting unit to said second micro-processing unit via said first receiver unit;

d. performing a matching process on said pairing signal wherein said matching process is comprised of assigning a first time interval to said pairing signal;

e. storing said pairing signal to said second second memory unit;

f. transmitting said pairing signal back to said first micro-processing unit via said second transmitting unit to said second micro-processing unit via said second receiver unit at and storing pairing signal to said first memory unit;

g. obtaining at least one data point of a tire by said first detection unit;

h. transmitting said data point of a tire by said first micro-processing unit via said first transmitting unit to said second micro-processing unit via said first receiver unit at said time of transmission;

i. synchronized retrieval and storing at least one data point of a vehicle by said main controller at second memory unit via said second micro-processing unit upon detecting said data point of a tire meeting one or more predetermined criterion.

2. The method of claim 1 wherein said data point of a vehicle comprised of vehicle velocity.

3. The method of claim 1 wherein said data point of a vehicle comprised of vehicle acceleration.
