Abstract

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 result; and a low pressure determining unit which determines a low pressure of a tire mounted on a vehicle using the set critical value.

Description

technical field [0001] The present invention relates to a tire pressure monitoring device and its method, more specifically, to a tire pressure monitoring device and its method considering the low pressure condition and capable of accurately judging the low pressure of a tire mounted on a vehicle. Background technique [0002] The air pressure of the tire is one of the elements that the car can run safely. If the air pressure of the tires is low, the vehicle can easily cause a major accident due to skidding, and the fuel efficiency will be greatly reduced due to the increase of fuel consumption. In addition, not only the life of the tire is shortened, but also the ride feeling and braking force will be greatly reduced. If the tire's air pressure drops, functional problems like reduced fuel efficiency, tire wear, etc. may occur. Not only that, but if the air pressure drops significantly, it may be impossible to drive or the tire may blow out, resulting in an accident, etc.,...
