Abstract: 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.

Abstract: 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.

Abstract: A tire monitor includes a sensor generating tire data. The tire monitor is configured to wake in response to a low frequency interrupt signal received from a remote source. Upon waking, the tire monitor scans Bluetooth Low Energy (BLE) channels to establish a BLE connection with the remote source. The tire monitor communicates with the remote source over the BLE connection.

Abstract: A system and method determine and/or adjust tire pressure sensor timings to transmit information using BLE information, regardless of the presence of other BLE systems. A tire pressure monitoring (TPM) system or other computing device receives transmission timing information from tire monitors that transmit using BLE and/or other BLE-enabled components. In response to determining an interference between the transmissions of the tire monitors and/or the components, timing of the transmissions from one or more of the tire monitors is altered to avoid the interference.

Abstract: Methods, apparatuses, systems, and computer program products for configuring a tire monitoring system are disclosed. In a particular embodiment, configuring a tire monitoring system includes determining a model identifier for a tire; identifying, in a database, one or more stiffness coefficients corresponding to the model identifier of the tire; and transmitting the one or more stiffness coefficients to a component of the tire monitoring system.

Abstract: A system for tracking tread wear of a tire of a vehicle includes a processor configured to obtain a new tire rotational count value representing expected rotations of the tire over a set distance if the tire were new. A position tracking device is coupled to the vehicle and configured to track a distance traveled by the vehicle and report the distance to the processor. A wheel speed sensor is coupled to the vehicle and configured to track rotations of the tire. The processor determines a current tire rotational count value representing the number of rotations of the tire over the set distance. The processor then determines a tire tread wear value based on the new tire rotational count value and the current tire rotational count value. A display device is configured to display indicia based on the tire tread wear value.

Abstract: Embodiments included herein are directed towards a method for estimating tire load. Embodiments may include determining a tire pressure associated with a tire and determining a tire angular velocity associated with the tire. Embodiments may further include obtaining one or more tire stiffness coefficients and determining a tire radial deformation based upon, at least in part, a length of a tire ground contact patch or a contact patch angle.
