Applying motion sensor data to wheel imbalance detection, tire pressure monitoring, and/or tread depth measurement

Abstract

A computer-based method to facilitate detecting wheel imbalance, a tire pressure problem, or excessive tread wear on tires of a moving vehicle is disclosed. The method includes collecting (e.g., from an accelerometer of a mobile personal computing device) data that represents vibration that results, at least in part, from the vehicle's motion, and determining, with a computer-based processor, whether the moving vehicle has wheel imbalance, a tire pressure problem, and/or excessive tire tread wear based at least in part on the vibration data produced by the accelerometer (and, possibly other data), where the mobile personal computing device and the accelerometer are moving with the vehicle when the data is being collected.
