System for the estimation of one or more parameters related to the load of a vehicle, particularly of the absolute value and the distribution thereof

A vehicle comprising:

• a system for the estimation of parameters (L, D) related to a load of a vehicle, said system comprising:
• first and second sensors for detecting respective first and second vehicle kinematic quantities, each sensor being suitable to generate signals representing the respective one of said vehicle kinematic quantities;
• a control unit comprising:
• first and second pairs of band-pass filters, each pair comprising first and second band-pass filters;
• one or more modules for determining frequency spectra pairs (FFT1,FFT2), a frequency spectra pair being associated with each of said first and second vehicle kinematic quantities, from the signals representing the respective vehicle kinematic quantity filtered in a first and in a second predetermined frequency band through the first and second band-pass filters of a respective pair of the band-pass filters;
• and
• one or more modules for determining a numeric value representing the vehicle load (L) in kilograms and a numeric value representing the load distribution (D) in the vehicle from said frequency spectra pairs (FFT1, FFT2),
• wherein said numeric value representing the load distribution in the vehicle (D) represents the longitudinal distance of the concentrated load of the vehicle from a predetermined reference point,
• wherein said numeric value representing the vehicle load (L) is a numeric absolute value representing the vehicle load (L), and said sensors comprise a sensor configured for detecting the vehicle vertical acceleration ({umlaut over (z)}) and for generating a signal representing the vehicle vertical acceleration, and a sensor configured for detecting the vehicle pitch angular speed ({dot over (ϑ)}) and for generating a signal representing the vehicle pitch angular speed,
• whereby the determination of said numeric value representing the vehicle load (L) and of said numeric value representing the load distribution in the vehicle (D) enables improvement in a stability of the vehicle.
