Abstract
Estimating a load bearing on a vehicle tire includes an inflation pressure measuring sensor for measuring tire inflation pressure and generating a measured tire inflation pressure signal; a deformation measuring sensor mounted in a tire region of the vehicle tire, the deformation measuring sensor in the form of a piezoelectric bending sensor generating a deformation signal estimating a length of a tire contact patch length as the senor rolls through a tire footprint. Tire rolling speed is estimated from the deformation signal and a peak to peak amplitude variation within the deformation signal is detected and measured. An artificial neural network receives the tire rolling speed estimation, the contact patch length estimation, the amplitude variation within the deformation signal, and the measured inflation pressure of the tire. The artificial neural network adaptively interprets the input data and generates an output load estimation based thereon.
