Abstract
A method for detecting a deflated condition of a tire, comprises the steps of (a) detecting the angular velocity of each wheel, (b) producing a signal proportional to the angular velocity detected, (c) detecting acceleration of the vehicle in a forward or backward direction, (d) obtaining a speed of the vehicle in the forward or backward direction by integrating the detected acceleration, (e) producing a signal proportional to the obtained speed of the vehicle in the forward or backward direction, and (f) arithmetically processing the signals produced in steps (b) and (e). In step (f), the angular velocity of each wheel at the speed in the forward or backward direction obtained in step (d) is obtained from a normal wheel angular velocity table previously prepared; and the result is compared with the angular velocity detected in step (a), and if the difference therebetween is within the range of 0.05% to 0.60%, a device for warning of a deflated tire is operated.
