摘要： A method of determining the velocity (ν) of a vehicle is provided. The vehicle has at least one pair of a front and a rear wheel which are spaced by a wheel spacing ( B ). Front and rear wheel speed signals (ω) are determined which are indicative of the time dependent behavior of the front and rear wheel speeds, respectively. The front and rear wheel speed signals ( ω) are correlated in order to determine a specific correlation feature indicative of the time delay (τ) between the front wheel and rear wheel speed signals. The velocity (ν) of the vehicle is determined based on said correlation feature and the wheel spacing ( B ).

摘要： 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 ).

摘要： The invention is directed to a digital signal processing method and system for digitally processing a discretized in-put signal (12) provided in form of a plurality of discrete input signal values at corresponding discrete input time instants which are distributed non-equidistantly in time. The method comprises a conversion of the input signal (12) to a discretized output signal (16) representing the input signal (10) with discrete output signal values at discrete output time instants which are distributed equidistantly in time, wherein the conversion is carried out by a linear interpola-tion (14). The weight factors ( w ( i,n )) of the linear interpo-lation are derived from an impulse response function of a filter (18).
