Method for determining a force at the hub of a wheel of a vehicle while traveling and wheel suitable for allowing said method to be carried out
First Claim
1. A method for determining the force at the hub of a wheel of a vehicle while traveling, said wheel comprising a rim and at least one deformation sensor directly associated with said rim in at least one predetermined position and arranged according to at least one predetermined orientation, comprising the steps of:
- detecting at least one deformation component of said rim during travel through said at least one deformation sensor; and
applying to said at least one deformation component, during travel, a correlation parameter characteristic of said rim, between the force at the hub and the relative deformation of said rim to determine at least one force component at the hub correlated with said at least one deformation component of said rim.

Abstract
A method for determining the force at the hub of a wheel of a vehicle while traveling. The wheel includes a rim and at least one deformation sensor directly associated with the rim in at least one predetermined position and arranged according to at least one predetermined orientation. The method includes the steps of detecting at least one deformation component of the rim during travel through the at least one deformation sensor; applying to the at least one deformation component, during travel, a correlation parameter characteristic of the rim, between the force at the hub and the relative deformation of the rim to determine at least one force component at the hub correlated with the at least one deformation component of the rim. The determining of the correlation parameter preferably takes place through experimental tests that include the steps of providing a sample wheel having a rim substantially the same as that of the wheel and determining at least one correlation coefficient between at least one force component acting upon the sample wheel at the hub along at least one predetermined direction and at least one respective deformation component of the rim of the wheel.
