1. A tire location discrimination device, comprising:
- a plurality of pressure gauges each measuring internal pressure of a plurality of tires; and
an operation unit receiving and processing pressure signals each generated from the plurality of pressure gauges, respectively, according to curves of a road surface,wherein signals values or phase differences of the pressure signals are compared with each other by the operation unit to discriminate the tire locations.

20. A tire location distinction method, comprising:
-
measuring, by a plurality of pressure gauges, respectively, internal pressure of a plurality of tires; collecting and processing pressure signals each generated from the plurality of pressure gauges, respectively, according to curves of a road surface; performing grouping to discriminate signals having high similarity between the pressure signals as a location of a front wheel or a rear wheel of the tires by allowing an operation unit to compare magnitudes and phases of the pressure signals at the same time and to discriminate signals having high similarity between the pressure signals as a location of a left wheel or a right wheel by allowing the operation unit to compare magnitudes or phases of the pressure signals in a time difference between the front and rear wheels; and comparing at least one of the pressure signals with signals of motion sensors mounted in a vehicle to discriminate a location of at least one tire and automatically discriminate locations of the remaining pressure signals.
