Abstract
The object of the present invention is a system (1) for the estimation of one or more parameters (L, D) related to the load of a vehicle. The system comprises: —one or more sensors for detecting one or more kinematic quantities of the vehicle (I) suitable to generate signals representing said vehicle kinematic quantities; —one or more modules (2) for determining one or more frequency spectra pairs (FFT1,FFT2), each pair associated to one of said one or more vehicle kinematic quantities (I), from the signal representing the respective vehicle kinematic quantity filtered in a first and in a second predetermined frequency bands; —One or more modules (7) for determining said one or more parameters (L, D) related to the load of the vehicle, from said one or more frequency spectra pairs (FFT1,FFT2).
