Methods, apparatuses, computer program products, systems for enhanced tracking of tire tread wear are disclosed. In a particular embodiment, a tire monitoring sensor (TMS) detects a tread wear reporting event, generates tread wear data including at least a rotational time period, and transmits the tread wear data to a vehicle control system (VCS). The rotational time period may be a measure of time the tire takes to complete a particular number of revolutions. The VCS receives, from the TMS, the tread wear data including at least the rotational time period, determines a current circumference of the tire based on at least the rotational time period, and determines a tread wear value based on at least the current circumference.

Enhanced tracking of tire tread wear

Determining tread depth using data from a tire mounted sensor (TMS), including: determining, based on data collected by the tire mounted sensor, a tire deformation for a tire; determining, based on the tire deformation, an effective rolling radius of the tire; and determining, based at least on the effective rolling radius of the tire, an estimated tread depth for the tire.

Determining tread depth using data from a tire-mounted sensor

Methods and systems for adaptively configuring a tire mounted sensor (TMS) with vehicle-provided parameters are disclosed. A vehicle control unit obtains data from vehicle sensors and other sources and transmits configuration parameters to the TMS. The TMS signal processing components are configured according to the configuration parameter to minimize the number of tire rotations needed to generate an accelerometric profile and extract a tire feature. The extracted feature is transmitted back to the vehicle control unit with the aim of minimizing the computational resources and battery consumption of the TMS.
