Abstract

A preliminary positioning method for a TPMS uses a receiver to receive a tire pressure signal, then obtains the ID code contained in the obtained tire pressure signal, then compares the ID code with the corresponding ID codes stored in the database, and defines the ID code as a known ID code, when the ID code is found to match with one of the corresponding ID codes prestored in the database. Repeating the above steps until the ID codes of all received tire pressure signals all have been compared. If the number of the known ID codes is equal to the number of the sensors, the known ID codes are designated as specific tires according to an indication of the respective tire pressure signals, so that the positioning function can be achieved in a short period of time.

Claims12

Dependent claims

A preliminary positioning method for a tire pressure monitoring system, wherein the tire pressure monitoring system is installed in a vehicle which has a plurality of tires, and comprises a receiver and a plurality of sensors, each of the sensors is installed in the tires to produce a tire pressure signal which contains a tire pressure data and an ID code, the tire pressure signal is sent to the receiver, the receiver includes a database in which is stored a plurality of corresponding ID codes;

the preliminary positioning method comprising the following steps:
a first step including:
receiving the tire pressure signal and obtaining the ID code contained in the received tire pressure signal;
a second step including:
comparing the obtained ID code with the corresponding ID codes stored in the database, defining the obtained ID code as a known ID code when the obtained ID code is found to match with one of the corresponding ID codes;
a third step including:
repeating the first and second steps until all ID codes of all received tire pressure signals have been compared;
and
a fourth step including:
counting the number of the known ID codes;
either designating each of the known ID codes as a specific tire when the number of the known ID codes is equal to the number of the sensors;
or implementing a procedure of adding tire pressure information when the number of the known ID codes is less than the number of the sensors;
wherein the procedure of adding tire pressure information includes the following steps:
a step A includes:
obtaining a signal parameter of all the received tire pressure signals whose ID codes are not defined as the known ID codes;
a step B includes:
defining the ID code of one of all the received tire pressure signals which have not been defined as the known codes as the known code, according to the signal parameter;
a step C includes:
repeating the steps A and B until the number of the known ID codes is equal to the number of the sensors;
and
a step D includes:
designating each of the known ID codes as the specific tire.
