Claim 3:
4. A tire damage detection system comprising:
an acquisition device installed onboard a motor vehicle equipped with two or more wheels fitted with tires, wherein the acquisition device is coupled to a vehicle bus of the motor vehicle and configured to acquire, via the vehicle bus, a signal indicative of a speed of a wheel of the motor vehicle;
a processing system configured, in a preliminary stage, to
acquire test-related wheel speeds during performed tests involving test tire impacts against or on different obstacles at different motor vehicle speeds,
compute test-related normalized wheel speeds based on the test-related wheel speeds, and
determine and store a predefined tire damage model to be used in a 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;

the processing system further configured, in the tire damage detection stage, to
receive, from the acquisition device, quantities indicative of the wheel speed,
compute, 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
detect 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.
