Abstract
A system for detecting deflated tires by making a relative comparison among rotation speeds of tires attached to a vehicle. The system includes a rotation speed information detection means for detecting rotation speed information of the tires; a rotation speed calculation means for calculating rotation speeds of the tires; and a determination means for determining deflated tires by comparing a decreased pressure determination value using the calculated rotation speeds with a predetermined threshold value. The determination means determines that the vehicle is going straight when it is found, with regard to factors composed of a lateral G, a yaw rate, and a steering angle of the vehicle, at least two of the factors including the yaw rate show that a difference between the maximum value and the minimum value at a predetermined time is lower than a predetermined value, thereby detecting deflated tires.
