Tire pressure estimation
First Claim
1. A method for estimating the occurrence of a specific tire pressure deviation between actual and nominal pressure values for one or a plurality of wheels (i), comprising the following steps:
- a) subsequently obtaining one or more wheel radius analysis measurement values (Δ
R) from a wheel radius analysis component (104), wherein the wheel radius analysis measurement values (Δ
R) are related to single wheel radius values (Δ
ri) of which each is indicative of the wheel radius of a particular wheel (i);
b) subsequently obtaining one or more wheel vibration data values (Δ
fi) from a wheel vibration analysis component (102), wherein each of the wheel vibration data values (Δ
fi) is indicative of a vibration phenomena in the time dependent behavior of the rotational velocity of a particular wheel (i); and
c) calculating one or more tire pressure output values (η
i, Δ
pi) on the basis of both the wheel radius analysis measurement values (Δ
R) and the wheel vibration data values (Δ
fi) wherein each tire pressure output value (η
i, Δ
pi) is indicative of the specific tire pressure deviation for a particular wheel (i).

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 (ΔR) are subsequently obtained from a wheel radius analysis component (104), wherein the wheel radius analysis measurement values (ΔR) are related to single wheel radius values (Δri) of which each is indicative of the wheel radius of a particular wheel (i). One or more wheel vibration data values (Δfi) are subsequently obtained from a wheel vibration analysis component (102), wherein each of the wheel vibration data values (Δfi) is indicative of a vibration phenomena in the time dependent behavior of the rotational velocity of a particular wheel (i). One or more tire pressure output values (ηi, Δpi) are calculated on the basis of both the wheel radius analysis measurement values (ΔR) and the wheel vibration data values (Δfi) wherein each tire pressure output value (ηi, Δpi) is indicative of the specific tire pressure deviation for a particular wheel (i).
