Abstract
A method for detecting, evaluating, and indicating a tire air pressure value. Information signals are compared with a plurality of desired value curves having a tolerance range and an average value for the atmospheric temperature, whereupon these signals are evaluated. The pressure deviation, as a function of the desired value tolerance ranges, is assigned a specific pressure state, from which an acutal air pressure state is indicated that takes into account regional and seasonal pressure and temperature influences. Furthermore, a maximum speed and a permissible speed can be determined during emergency operation, or a state of emergency operation can be determined.
