Provided is a tire pressure monitoring apparatus using a mass of a vehicle including: a radius analyzing unit; a frequency analyzing unit; a mass estimating unit; a calibration unit; and a low pressure determining unit.

Apparatus and method for monitoring tire pressure using mass of vehicle

The present invention relates to an apparatus and a method for monitoring tire pressure according to a tire characteristic. An apparatus for monitoring a tire pressure according to a tire characteristic according to an exemplary embodiment of the present invention includes: a frequency calculating unit calculating a speed interval specific mean frequency by accumulating and averaging frequency data for each speed interval; a tire searching unit searching a tire corresponding to the calculated speed interval specific mean frequency by comparing the calculated speed interval specific mean frequency with a prestored tire specific mean frequency; a low-pressure threshold selecting unit selecting a low-pressure probability threshold depending on the searched tire; and a low-pressure determining unit determining a low pressure by calculating an integration low-pressure probability by integrating frequency and dynamic radius low-pressure probabilities and comparing the selected low-pressure probability threshold and the calculated integration low-pressure probability.
