| 摘要 |
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).
