Method and apparatus for detecting decrease in tire air-pressure, and selecting program for the thresholds for judging decompression of tire |
摘要 |
A method for detecting decrease in tire air-pressure for detecting decrease in internal pressure of a tire on the basis of rotational information obtained from tires attached to a vehicle. A threshold for judging decrease in air-pressure of following wheels is different from a threshold for judging decrease in air-pressure of driving wheels. Threshold for judging abnormalities in air-pressure are varied for judging abnormalities of tire air-pressures of following wheels and for judging abnormalities of tire air-pressure of driving wheels so that appropriate judgment of abnormalities in air-pressure can be performed.
