Abstract: Sensorised wheel hub unit and a method for detecting, in real time, forces and moments applied to an outer ring of the wheel hub unit in which piezoresistive ceramic plates are made of one piece with welded metal plates housed within respective recesses formed in an outer surface of the outer ring over respective races for rolling elements that there is a gap between the plates and a base wall of each recess; the temperature of the outer ring and the amplitude and frequency of first electrical signals (S1) associated with the sensors relating to the same race are analysed to determine a frequency value equal to the frequency of the first signal having the maximum amplitude and as many amplitude values (D1-Dn) as there are sensors associated with that race and each equal to the maximum amplitude of the first signal from each sensor, corrected according to temperature.

Abstract: A method and system for detecting forces and moments acting on a vehicle wheel, wherein an outer ring of a wheel hub unit has a plurality of strain sensors configured to generate first signals (Ds1) proportional to mechanical stresses on the outer ring and a temperature sensor generating a second signal (Ds2). Further, the detection system comprises a second processing unit configured to process third signals (Dv1,n) corresponding to selected vehicle state parameters; and a third processing unit that receives the third signals and the pseudo-sinusoidal signal and calculates said forces and moments on the vehicle wheel.
