    • 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 (Δ R ) 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 ( Δr i ) of which each is indicative of the wheel radius of a particular wheel ( i ). One or more wheel vibration data values (Δƒ i ) are subsequently obtained from a wheel vibration analysis component (102), wherein each of the wheel vibration data values (Δƒ i ) 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 ( η i , Δ pi ) are calculated on the basis of both the wheel radius analysis measurement values (Δ R ) and the wheel vibration data values (Δƒ i ) wherein each tire pressure output value ( η i , Δ pi ) is indicative of the specific tire pressure deviation for a particular wheel ( i ).
    • 提供了一种估计一个或多个轮(i)的实际和标称压力值之间的特定轮胎压力偏差的发生的方法。 随后从车轮半径分析部件(104)获得一个或多个车轮半径分析测量值(DeltaR),其中车轮半径分析测量值(ΔR)与单轮半径值(Deltari)相关, 特定车轮(i)的车轮半径。 随后从车轮振动分析部件(102)获得一个或多个车轮振动数据值(Deltafi),其中,每个车轮振动数据值(Deltafi)表示时间相关行为的振动现象, 特定车轮(i)。 基于轮胎半径分析测量值(DeltaR)和轮胎振动数据值(Deltafi)计算出一个或多个轮胎压力输出值(etai,Deltapi),其中每个轮胎压力输出值(etai,Deltapi)指示 对于特定车轮(i)的具体轮胎压力偏差。
