  • Apparatus and method for monitoring tire pressure using speed section
    Patent number: 9757999
    Abstract: The present invention relates to an apparatus and a method for monitoring a tire pressure using a speed section. The tire pressure monitoring apparatus using a speed section of the present invention includes a frequency measuring unit which measures frequency data for every wheel mounted on a vehicle; a frequency calculating unit which calculates a mean frequency for every speed section by accumulating the measured frequency data for every predetermined speed section to obtain a mean; a frequency calibration unit which performs the frequency calibration by calculating a deviation of the mean frequency for every adjacent speed section and comparing the calculated deviation of the mean frequency with the predetermined frequency range; and a low pressure determining unit which determines a low pressure by performing the frequency analysis in accordance with the speed section in which the frequency calibration is completed.
