  • Publication number: 20200189327
    Abstract: A tire data information system includes at least one tire that supports a vehicle and a processor. At least one sensor is mounted on the tire and is in electronic communication with the processor. The sensor measures a temperature and a pressure of the tire. A memory for storing tire identification information is in electronic communication with the processor. Tire wear state means generate a wear state of the tire and are in electronic communication with the processor. Tire wear rate means generate a wear rate of the tire and are in electronic communication with the processor. Transmission means transmit the temperature, pressure, identification information, wear state, and wear rate of the tire to a display device that is accessible to a user of the vehicle. The display device includes indicators for showing the temperature, pressure, identification information, wear state, and wear rate to the user.

  • Publication number: 20200182746
    Abstract: A tire wear state estimation system includes a CAN bus system disposed on a vehicle. A tire supporting the vehicle is mounted on a wheel. A wheel sensor unit is mounted on a structure adjacent the wheel, and the wheel sensor unit includes a longitudinal acceleration sensor to generate a longitudinal acceleration signal. The wheel sensor unit also includes a vertical acceleration sensor to generate a vertical acceleration signal, and transmission means to communicate the longitudinal acceleration signal and the vertical acceleration signal to the CAN bus system. A processor receives the longitudinal acceleration signal and the vertical acceleration signal. An extractor extracts a tire translational mode from the longitudinal acceleration signal and a tire vertical mode from the vertical acceleration signal. The tire translational mode and the tire vertical mode are input into a classifier to generate a wear state estimation for the tire. A method is also provided.

  • Patent number: 10603962
    Abstract: A tire wear state estimation system includes at least one sensor disposed on a vehicle and a CAN bus system. The sensor measures selected parameters associated with the vehicle and communicates data for the selected parameters through the CAN bus system, including a first set of data, a second set of data and a third set of data.

An acceleration slip estimator receives the second set of data and the estimated rolling radius to estimate the slip of the tire during acceleration. A braking slip estimator receives the third set of data and the estimated rolling radius to estimate the slip of the tire during braking. A tire slip analyzer correlates the acceleration slip estimation and the braking slip estimation and generates an estimated wear state of the tire.

  • Patent number: 9995654
    Abstract: A vehicle state estimation system and method uses an observer model to make cornering stiffness estimates from tire-based sensor data and vehicle-based sensor data throughout transient and non-transient operational maneuvers of a vehicle. A cornering stiffness identifier extracts transient-state cornering stiffness estimates from the cornering stiffness estimates made by the observer model and extracts from the transient-state cornering stiffness estimates an optimal transient-state cornering stiffness estimate having a substantially highest confidence measure for use by a vehicle control system.
