Beschreibung
Zusammenfassung:	A method, computer program product and apparatus for estimating the pneumatic pressure of a tire on a wheel of a vehicle comprising the steps of: receiving as an input data from a first vehicle status sensor signal from a sensor of said vehicle, said sensor signal representing a vehicle status dependent on the pneumatic pressure of said tire; calculating a tire pressure dependent value by means of an adaptive filter that is based on a predetermined first tire pressure dependent model of the vehicle status; calculating an estimate of first parameter values of said adaptive filter dependent on said first vehicle status sensor signal and on the offset for said sensor signal; and calculating a tire pressure indication value dependent on said first tire pressure dependent model parameter values and on a predetermined second tire pressure dependent model of the vehicle status. The vehicle is a two wheeled vehicle such as a motorcycle, and said adaptive filter comprises front and rear wheel angular velocity parameters.
