Abstract
It is the purpose of the present invention to provide a method, apparatus and program for alarming abnormality in tire air-pressure capable of precisely detecting decrease in tire air-pressure even at actuation of air suspension in a vehicle equipped with air suspensions. The present invention discloses a method for alarming abnormality in tire air-pressure informing decrease in tire air-pressure mounted on a vehicle, comprising a step of judging whether loads applied on respective tires are changed by the influence of air suspensions based on the difference of the heights of strokes between left wheel and right wheel in a vehicle equipped with the air suspensions and affect the rotational wheel speeds of tires or not, and increasing threshold for carrying out the judgment of decrease in tire air-pressure when the air suspensions provide influence.
