Apparatus, method and program for alarming abnormality in tire air-pressure |
摘要 |
The present invention provides an apparatus, method and program for detecting abnormality in tire air-pressure which allow detecting abnormality in tire air-pressure even if pressure in a tire is completely zero. The apparatus for alarming abnormality in tire air-pressure includes means of (1) calculating the acceleration variations of respective tires from accelerations of the tires calculated by rotational wheel velocities; (2) comparing the calculated acceleration variations of the respective tires; and (3) detecting air-pressure in a tire is abnormal when the acceleration variation of the tire is larger than the acceleration variations of the remaining tires as a result of comparison.
