<p>The present invention relates to a device and a method for monitoring tire pressure to identify the location of a TPM sensor attached to a tire using the tooth data of an ABS. The present invention identifies the location of the TPM sensor by estimating the tooth data of a wheel based on wheel location angle information sensed by a rotation detection sensor of the TPM sensor using the fact that each wheel has different variations according to the condition of the tire and recognizing that a tire having the same or approximate value to an estimated value has the TPM sensor attached to it. [Reference numerals] (AA) Start; (BB) End; (S700) Transmitting after measuring first location angle information (罐_1); (S710) Storing wheel tooth data (WT1) when the 罐_1 is received; (S720) Transmitting after measuring second location angle information (罐_2); (S730) Storing wheel tooth data (WT2) when 罐_2 is received; (S740) Converting to wheel tooth difference (WTD) after calculating the number of 罐_2 - 罐_1; (S750) Calculating wheel tooth data (WTe2) expected when the 罐_2 is received by using WT1 and WTD; (S760) Assigning the location of the WT2 location closest to WTe2 to a received sensor ID</p> |
