A system and method for issuing a tire pressure deviation in a vehicle's tire is described. The system may include a calculation unit adapted to calculate temporally successive output signals indicative of a tire pressure condition in the vehicle's tire on the basis of temporally successive vehicle's signals. The system may also include a calibration unit adapted to determine a calibration value on the basis of a number of temporally successive output signals from the calculation unit. The system may also include a detection unit configured to detect a tire pressure deviation in the vehicle's tire on the basis of further temporally successive output signals from the calculation unit and the calibration value from the calibration unit, after determination of the calibration value by the calibration unit.

Method, system and computer program of detecting a tire pressure device

The invention provides a system, a method and a computer program of estimating tire pressure deviations in a number of tires of a vehicle wherein a plurality of possible constellations of one or more pressure deviating tires exists. The system comprises a plurality of pressure deviation detectors (), wherein each of the detectors () is adapted to detect at least one of the pressure deviating tire constellations. The system further comprises an output unit () which is adapted to provide for a warning if one of the pressure deviation detectors () detects at least one of the pressure deviating tire constellations.

System, method and computer program of estimating tire pressure deviations

The invention is directed to a system, a method and a computer program including program code for carrying out the method, when executed on a processing system, of estimating a tire pressure deviation of a vehicle's tire (). The system includes an input section () adapted to receive as an input signal a vehicle signal, a calculation section () adapted to calculate at least one shape factor of a resonance peak associated with the vehicle signal spectrum () on the basis of the input signal, and a determination section () adapted to derive, depending on said at least one shape factor, a tire pressure signal indicative of a tire pressure deviation within the vehicle's tire ().
