Claim 0:
1. A tire damage detection method comprising:
a tire damage detection stage comprising
acquiring, by 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, signals indicative of speeds of the motor vehicle and of a wheel of said motor vehicle,
outputting, by the acquisition device, quantities indicative of the speeds of the motor vehicle and of the wheel thereof,
receiving, by a processing system storing a predefined tire damage model from the acquisition device, the quantities indicative of the speeds of the motor vehicle and of the wheel of said motor vehicle,
computing, by the processing system, based on the quantities indicative of the speeds of the motor vehicle and of the wheel of said motor vehicle, a normalized wheel speed indicative of a ratio of the wheel speed to the 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; and

a preliminary stage that comprises:
performing tests involving test tire impacts against/on different obstacles at different motor vehicle speeds,
acquiring test-related wheel and motor vehicle speeds during the performed tests,
computing test-related normalized wheel speeds based on the test-related wheel and motor vehicle 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 and the test-related motor vehicle speeds that correspond to the test tire imp acts.
