Apparatus and method for monitoring tire pressure considering low pressure situation

摘要

The present invention relates to an apparatus and a method for monitoring a tire pressure considering a low pressure situation. Provided is a tire pressure monitoring apparatus considering a low pressure situation including: a radius analyzing unit which calculates a radius analysis value using a relative velocity difference and an average velocity calculated from wheel velocities of the wheels mounted on the vehicle; a critical value setting unit which compares the calculated radius analysis value with a predetermined determination reference value and sets different critical values in accordance with the comparison resu and a low pressure determining unit which determines a low pressure of a tire mounted on a vehicle using the set critical value.
