METHOD AND SYSTEM FOR MONITORING THE MASS OF AN OBJECT

A method for monitoring the mass of an object 10 comprising the steps of: (i) applying a vibratory force to the object 10, (ii) providing a sensor or sensors 14 configured to measure vibrations of the object in response to the force, (iii) measuring vibration data from the sensor(s) 14, and (iv) com...

Summary:A method for monitoring the mass of an object 10 comprising the steps of: (i) applying a vibratory force to the object 10, (ii) providing a sensor or sensors 14 configured to measure vibrations of the object in response to the force, (iii) measuring vibration data from the sensor(s) 14, and (iv) comparing the vibration data or a parameter derived therefrom to reference data or one or more reference parameters, so as to determine the mass of the object. Preferably, the object 10 is a vehicle. The vibratory force may be provided by an integral vehicle component, for example a vehicle engine 12. The mass may be determined through use of a distribution function, for example standard deviation, linear correlation function or the Pearson correlation function. A distribution value may be obtained from two of velocity, displacement and acceleration. The sensors may be accelerometer, laser or optically based.
