Method, system and computer program for estimation of the pressure

A system of estimating a tire pressure of a vehicle's tire, comprising:

• an input section adapted to receive as an input signal a pressure related signal;
• a calculation section adapted to calculate at least one shape factor (H;
• W;
• S;
• HNL;
• I;
• ANL) of a resonance peak associated with a spectrum of the pressure-related signal on the basis of the input signal;
• and
• a determination section adapted to derive, depending on said at least one shape factor (H;
• W;
• S;
• HNL;
• I;
• ANL), a tire pressure signal indicative of a tire pressure within the vehicle's tire, wherein the shape factor (H;
• W;
• S;
• HNL;
• I;
• ANL) comprises at least one of:
• the integral (I) of the resonance peak, and
• the area (ANL) under the peak down to the noise floor level.

A non-transitory computer readable medium including program code for carrying out a method, when executed on a processing system, of estimating a tire pressure of a vehicle's tire, the method comprising:

• receiving as an input signal a pressure-related signal;
• calculating at least one shape factor (H;
• W;
• S;
• HNL;
• I;
• ANL) of a resonance peak associated with a spectrum of the pressure-related signal on the basis of the input signal;
• and
• determining, depending on said at least one shape factor (H;
• W;
• S;
• HNL;
• I;
• ANL), a tire pressure signal indicative of the tire pressure within the vehicle's tire, wherein the shape factor (H;
• W;
• S;
• HNL;
• I;
• ANL) comprises at least one of:
• the integral (I) of the resonance peak, and
• the area (ANL) under the peak down to the noise floor level.
