1. the method for the tire pressure of a tire of monitoring one vehicle wherein, is come continuous tire pressure observed reading of sensing time through device for pressure measurement, and is worth according to one of continuous tire pressure observed reading decision expression tire pressure change, and this method comprises:

  • One counting of one counting machine is set at a predetermined start value that is higher than a current tire pressure;

    To a plurality of time continuous gauging on-cycles each;

    (a) by device for pressure measurement sensing one tire pressure observed reading;

    (b) based on a value that determines from continuous on-cycle tire pressure observed reading to represent that tire pressure changes;

    (c) determine whether this counting arrives this value that the expression tire pressure changes;

    (d) when this counting arrives this value of expression tire pressure change, transmit the said tire pressure of part observed reading to a receiving element at least from a delivery unit, this counting that after transmission, resets this counting machine is this initial value and repeating said steps (a) to (d);

    And(e) when this counts this value that no show still representes that tire pressure changes, this counting that reduces this counting machine also repeating said steps (a) to (e).
