Tire pressure monitoring system
First Claim
1. A computer program with a program code, stored on a computer readable medium and executable by a computer system, for performing a method of monitoring the tire pressure in a vehicle tire, in which temporally successive tire pressure measured values are sensed by a pressure detector, and at least part of the tire pressure measured values is transmitted from a transmitter to a receiver with a variable frequency of occurrence, wherein the frequency of occurrence is derived from the sensed tire pressure measured values, the computer program comprising:
- instructions for decrementing or incrementing a count of counter beginning with a starting value;
instructions for comparing the count with a tire pressure change dependent parameter derived from the sensed tire pressure measured values; and
instructions for triggering a transmission when the count reaches the tire pressure change dependent parameter.

Abstract
In the system for monitoring tire pressure in a tire of a vehicle, temporally successive tire pressure measured values are sensed by a transmitting unit, and at least part of the tire pressure measured values is transmitted to a receiving unit with a variable frequency of occurrence, wherein the frequency of occurrence is derived from the sensed tire pressure measured values by means of a control unit.

2. A computer program with a program code, stored on a computer readable medium and executable by a computer system, for performing a method of monitoring tire pressure in a tire of a vehicle, wherein tire pressure measured values are sensed by a pressure detector at successive measuring time instants, and the tire pressure measured values are transmitted from a transmitter to a receiver at successive transmission time instants, wherein the distance between successive measuring time instants and/or the distance between successive transmission time instants is adjustable and is derived from the sensed tire pressure measured values, the computer program comprising:
-
instructions for sensing a plurality of tire pressure measured values; instructions for ascertaining an instantaneous pressure dynamics state in the tire occurring as a result of the instantaneous driving situation of the vehicle from the plurality of tire pressure measured values, comprising; instructions for evaluating a plurality of successive tire pressure measured values to obtain a tire pressure dependent driving situation parameter; instructions for comparing the tire pressure dependent driving situation parameter with a comparison parameter; and instructions for ascertaining the instantaneous pressure dynamics state from the comparison; and instructions for adjusting the measuring time instants or the transmission time instants corresponding to the ascertained instantaneous pressure dynamics state.
