Abstract: A system for characterizing a vehicle tire is provided. The system includes a testing assembly configured to support the vehicle tire. The assembly includes a force-moment transducer configured to gather force information from the vehicle tire in response to a stimulus on the vehicle tire. The system further includes an accelerometer coupled to the vehicle tire and configured to gather vibration information from the vehicle tire in response to the stimulus on the vehicle tire. The system further includes a post-processing system configured to receive the vibration information from the accelerometer and the force information from the force-moment transducer. The post-processing system is further configured to extract resonant frequencies from the vibration information and the force information.

Abstract: A method for evaluating a vehicle tire is provided. The method obtains, by at least one vehicle onboard motion sensor, vibration data associated with a corner of a vehicle, the vehicle tire being located at the corner; detects an inflation pressure value for the vehicle tire; receives, from a vehicle onboard computer system, tire age data associated with the vehicle tire; calculates remaining tread groove depth for the vehicle tire, based on the vibration data, the inflation pressure data, and the tire age data; and performs a task, based on the remaining tread groove depth for the vehicle tire, wherein the task comprises at least one of: presenting a notification of the remaining tread groove depth to a driver, and setting a code onboard the vehicle, wherein the code is associated with service notifications.

Abstract: Methods and systems are provided for determining frequencies associated with tire crown bending. The system includes a vibration generating device configured to excite vibrations through a tire. The system further includes a vibration sensing arrangement configured to sense vibrations at a plurality of sensing points on the tire. A computer is in communication with the vibration sensing arrangement and configured to determine a first frequency associated with bending of the crown of the tire based at least partially on phase differences between the sensed vibrations at the plurality of points on the tire.
