Abstract: 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 (2). The system includes an input section (100) adapted to receive as an input signal a vehicle signal, a calculation section (200) adapted to calculate at least one shape factor of a resonance peak associated with the vehicle signal spectrum (2) on the basis of the input signal, and a determination section (300) 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 (2).

Abstract: 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 the tire low pressure warning of a vehicle. The system comprises an input unit (3) adapted to receive a vehicle signal. It further comprises a determination unit (2,4,5) adapted to determine a tire pressure signal (P) indicative of a tire pressure deviation in the vehicles tire on the basis of the vehicle signal. Finally, it comprises a warning unit (10) adapted to issue a warning signal only after the tire pressure signal (P) has indicated a predetermined pressure deviation (?P0) for a minimum period of time (?Tmin).

Abstract: A method of estimating the occurrence of a specific tire pressure deviation between actual and nominal pressure values for one or a plurality of wheels (i) is provided. One or more wheel radius analysis measurement values (?R) are subsequently obtained from a wheel radius analysis component (104), wherein the wheel radius analysis measurement values (?R) are related to single wheel radius values (?ri) of which each is indicative of the wheel radius of a particular wheel (i). One or more wheel vibration data values (?ƒi) are subsequently obtained from a wheel vibration analysis component (102), wherein each of the wheel vibration data values (?ƒi) is indicative of a vibration phenomena in the time dependent behavior of the rotational velocity of a particular wheel (i).
