Claim 0:
1. A tire damage detection method comprising:
a tire damage detection stage that comprises:
providing an acquisition device, which is installed on board a motor vehicle equipped with two or more wheels fitted with tires, and which is coupled to a vehicle bus of the motor vehicle, and a processing system storing a predefined tire damage model;
acquiring, by the acquisition device from the vehicle bus, a signal indicative of a speed of a wheel of the motor vehicle;
outputting, by the acquisition device, quantities indicative of the wheel speed;
receiving, by the processing system from the acquisition device, the quantities indicative of the wheel speed;
computing, by the processing system, based on the quantities indicative of the wheel speed, a normalized wheel speed indicative of a ratio of the wheel speed to an average wheel speed indicative of motor vehicle speed; and
detecting, by the processing system, a potential damage to a tire of the wheel of the motor vehicle based on the predefined tire damage model and on the normalized wheel speed;

a preliminary stage that comprises:
performing tests involving test tire impacts against or on different obstacles at different motor vehicle speeds;
acquiring test-related wheel speeds during the performed tests;
computing test-related normalized wheel speeds based on the test-related wheel speeds; and
determining the predefined tire damage model to be used by the processing system in the tire damage detection stage based on the test-related normalized wheel speeds corresponding to the test tire impacts and of associated test-related average wheel speeds.
