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: An apparatus and system for addressing road noise are provided. The apparatus is configured to determine at least one from among a location of a vehicle and a noise feature of a road on which the vehicle is traveling, retrieve road noise cancellation information based on the determined at least one from among the location of the vehicle and the noise feature of the road on which the vehicle is traveling, and output a signal to cancel road noise based on the road noise cancellation information. The apparatus may be installed in vehicle to address road noise heard by occupants of the vehicle.
