Abstract
A method of monitoring a tire pressure, comprises the steps: measuring at least one parameter that influences the tire pressure, calculating the optimum tire pressure ρopt on the basis of the at least one measured parameter, comparing a measured tire pressure p with the optimum tire pressure ρopt in order to generate a deviation signal in the event of a predetermined deviation.

A method of monitoring a tire pressure, comprising the steps:
- measuring at least one parameter that influences the tire pressure;
- calculating an optimum tire pressure on the basis of the at least one measured parameter;
- comparing a measured tire pressure with the optimum tire pressure in order to generate a deviation signal in the event of a predetermined deviation, the predetermined deviation being defined by an upper and lower limit and, in each case when the deviation signal generated exceeds the upper limit or falls below the lower limit, a deviation value is increased in order to generate an alarm signal when the deviation value reaches a predetermined threshold value, and the deviation value is reduced when no deviation signal is present.
A system for monitoring a tire pressure, comprising
- at least one tire to be monitored;
- at least one sensor for measuring at least one parameter of the at least one tire that influences the air pressure;
- an air pressure sensor for measuring a current tire air pressure;
- and
- an evaluation unit, which receives the at least one parameter measured by the sensor and measured data from the air pressure sensor and wherein the evaluation unit calculates an optimum tire pressure on the basis of the at least one measured parameter and compares the measured tire pressure with the optimum tire pressure in order to generate a deviation signal in the event of a predetermined deviation, wherein the predetermined deviation is defined by an upper and lower limit and, in each case when the deviation signal generated exceeds the upper limit and falls below the lower limit, a deviation value is increased in order to generate an alarm signal when the deviation value reaches a predetermined threshold value, and the deviation value is reduced when no deviation signal is present.
