Tire pressure monitoring system and method for registering identification code in the same
First Claim
Patent Images
1. A tire pressure monitoring system comprising:
- a plurality of sensor units, each of which senses a tire pressure of each tire and sends a signal indicative of the sensed tire pressure and an identification code uniquely assigned to each sensor unit; and
a monitoring unit that receives the signal from the sensor unit and monitors the tire pressure based on the identification code contained in the signal and the sensed tire pressure, wherein the monitoring unit has a register means for registering the stored identification code as an identification code of the sensor unit, the register means receives a signal indicative of an identification code via an external device, stores the identification code, compares the identification code contained in the signal from the sensor unit with the stored identification code, and register the stored identification code as an identification code of the sensor unit.

Abstract
A tire pressure monitoring ECU receives inputs indicative of identification (ID) codes, each of which is uniquely assigned to each sensor unit provided to each tire of a vehicle, via a bar code reader. It stores the ID codes and compares it with ID codes contained in signals from the sensor units, respectively. When the result of the comparison satisfies a predetermined condition, the stored ID code is registered as an ID code corresponding to the uniquely assigned ID code of the sensor unit.

8. A method for registering an identification code uniquely assigned to each sensor unit in a tire pressure monitoring system for a vehicle including a plurality of sensor units for sensing a sensor signal containing the sensed tire pressure and the identification code, and a monitoring unit for monitoring a tire pressure of each tire based on the identification code and the sensed tire pressure contained in the sensor signal, including:
-
inputting respective identification codes of the sensor units to the monitoring unit;
comparing the identification code contained in the sensor with one of the inputted identification codes;
determining whether a result of the comparison satisfies a predetermined condition; and
registering the inputted identification code as an identification code corresponding to the uniquely assigned identification code of the sensor unit when the result satisfies the predetermined condition. - View Dependent Claims (9, 10)
