Method for detecting decompression of a tire and apparatus, and a program for determining the pressure of the tire can be read by a computer recording medium recorded

摘要

Based on the rotational speed of the wheel mounted on the vehicle A method for detecting the pressure of a tire is a predetermined from the step of detecting each rotational speed of the wheel, determining a ground speed of the vehicle, the rotational speed of the wheel calculating the speed information of the wheel speed information of the wheel in the step of calculating the decision value of the wheel position by comparing the speed information of said wheels with the ground speed of the vehicle, defining a ground speed of advance the vehicle internal pressure and comparing step of comparing the reference value and the decision value of the wheel positions of the wheels obtained by the location, and a step of determining the pressure of the tire based on the relationship between the comparison value with a predetermined threshold value of the reference value and the decision value. To expand the pressure-determining region of the tire, and can improve the pressure-determination accuracy.; Tire, wheel, rotating speed, ground speed, the same time a reduced pressure
