Abstract
A method for detecting abnormalities of a tire which detects abnormalities of a tire on the basis of rotational information obtained from tires attached to wheels of a vehicle. The method includes the steps of: detecting rotational pulses of wheels of the tires, calculating and storing rotational information of the tires on the basis of the rotational pulses, calculating and processing fluctuations in rotational pulse intervals in a single rotation of the tires on the basis of the rotational information, and storing data during driving which have been processed for each single rotation and performing prediction of abnormalities of a tire on the basis of changes in the data. Irregularities in rotational information of rotational pulses in a single rotation of the tires are detected for predicting a danger of abnormalities occurring to the tires to thus enable safe driving.
