A system for monitoring a brake disc of a braking system of a vehicle may have at least one source of an electromagnetic quantity having a set space-time pattern such as to interact with the brake disc in a manner dependent on the properties of the brake disc generating a respective variable signal. At least one sensor for detecting such variable signal may also be provided. The at least one detection sensor may face a set limited portion of an investigation surface of the brake disc. The set limited portion of the investigation surface being at least one set closed path that can be defined on the investigation surface of the brake disc. The detected variable signal being able to be analysed to determine at least one parameter of the brake disc based on a deviation of the time pattern of the detected variable signal with respect to a set reference time pattern.

A method of determining at least one parameter representative of at least one interaction along a longitudinal direction between a tyre and the ground, includes identifying a first parameter representative of a radial deformation of the tyre; determining a first and a second value of the first parameter in respective neighbourhoods of a first and a second longitudinal end of a footprint area defined between the tyre and ground; calculating a linear combination of the values thereby obtaining a second parameter; determining a third parameter representative of an angular velocity of the tyre; calculating a ratio between the second and third parameters; and calculating a main parameter, starting from the ratio, according to an algorithm, which main parameter is representative of a longitudinal interaction between the tyre and the ground.
