摘要： A method and apparatus for judging a decrease in internal pressure of a tire attached to a four-wheeled vehicle and for accordingly generating an alarm, wherein a threshold for judging decompression is set to be larger immediately after switching an ignition key ON when compared to a threshold for the vehicle in a normal running condition, and decompression is judged in a decompression judging time which is shorter than a time for the vehicle in a normal running condition. The threshold for judging decompression and the decompression judging time are returned to that for the normal running condition of the vehicle in the case no decompression is judged. It is thus possible to detect a condition in which a large decompressed condition exists at an early stage before running begins so that it is possible to improve the accuracy of detecting decompression.

摘要： An apparatus for alarming decrease in tire air-pressure in which decrease in internal pressure of tires is alarmed based on rotational information obtained from tires attached to a four-wheeled vehicle. The apparatus comprises a rotational information detecting means for detecting rotational information of each tire, a memory means for storing the rotational information of each tire, a calculating means for calculating reciprocals of turning radiuses based on rotational information of tires attached to a driving shaft and judged values from the rotational information of each tire, and a determining means for determining decrease in internal pressure from a relationship between the reciprocals of the turning radiuses and judged values. Determination of decompression can be reliably performed in the proximity of a region at which the lateral axis is 0, since the judged values (DEL values) obtained while the differentiation is restricted are focused at points at which the lateral axis is 0, that is, on the vertical axis.
