Abstract: A method for alarming decrease in tire air-pressure. The method includes the steps of: detecting rotational information of respective tires; respectively calculating and storing a wheel speed, a vehicle acceleration, a slip ratio between front and rear wheels, a running distance and a turning radius; accumulating the running distance, the moving-averaged vehicle acceleration and the slip ratio between front and rear wheels; obtaining a linear regression coefficient and a correlation coefficient of the vehicle acceleration and the slip ratio; judging whether at least a driving wheel tire has decompressed upon comparing a judged value of the linear regression coefficient and a reference value for internal pressure of the linear regression coefficient; and issuing an alarm of decrease in tire air-pressure. It is possible to improve performance and safety of the vehicle since it is possible to detect decompression of tires including at least one driving wheel tire, for instance, of not less than two wheel tires including the right and left driving wheels.
