Abstract: A method for estimating a condition of a tire is provided. The tire supports a vehicle and is mounted on a wheel. The wheel is rotatably mounted on an axle. A sensor is mounted on at least one of the tire, the wheel, the axle, and a component of the brake system. Vibrational data is measured with the sensor. The data from the sensor is transmitted to a processor, and the data is processed. The processed data is normalized and at least one of the normalized data and pre-processed data is input into a machine learning model. A condition estimation for the tire is generated, which includes at least one of a tread depth of the tire, a pressure of the tire, and a dual tire mismatch.

The reader includes an antenna for transmitting the radio frequency power signal to the sensor unit to actuate the one sensor unit. Upon actuation of the sensor unit, the sensor measures the parameter of the tire or wheel, and data from the sensor is transmitted from the sensor unit to the reader.

The tire-specific operating condition measurements include tire temperature, tire air inflation pressure, a tire wear state measurement and a tire load measurement. A rolling radius estimation model generates a tire rolling radius estimation compensated by the tire-specific operating condition measurements and a vehicle speed estimator generates a vehicle speed estimation based on the compensated tire rolling radius.
