Abstract: A real time tire pressure sensing system includes sensors to collectively generate signals corresponding to a contained tire air temperature, a contained inflation pressure, and an ambient temperature associated with a tire mounted on a vehicle. A processor determines an effective tire inflation pressure based on the generated signals and further at least on a calculated moving average of the ambient temperature (e.g., over a defined time period such as 24 hours) and generates real time notifications associated with the determined effective tire inflation pressure to specified user interfaces. At least one sensor may be an inflation pressure sensor configured to generate event-based signals corresponding to detected changes per unit pressure. The processor may further generate real time feedback control signals to an automatic tire inflation device, based on the determined effective tire inflation pressure, or enable and prompt manual control of the tire inflation device via the user interface.

Abstract: A tire wear state estimation system estimates forces and sliding velocity generated in a tire contact patch, determines frictional energy from the tire force and sliding velocity, and generates an estimate of tire wear state based upon the frictional work done by the tire. A tire wear estimate, pursuant to the system and methodology, is made by determining the amount of frictional work performed by the tire through the integrated use of tire-mounted, GPS sourced, and vehicle-mounted sensor information.

Abstract: An apparatus for monitoring deflection of a tyre including a non-transitory memory, storing tyre behavior information which relates tyre deflection to tyre load and tyre pressure; and a controller in communication with the memory. The controller is configured to: receive load information which relates to a load on the tyre; receive pressure information which relates to a pressure of the tyre; and determine a deflection of the tyre based on the received load information, the received pressure information, and the stored tyre behavior information.

Abstract: Data representing a ground contact time of a tire is transmitted from a tire side device, and received by a vehicle side device to calculate the ground contact time of the tire, to thereby calculate a ground contact length of the tire at that time. In a situation where a tire air pressure may change such as a tire exchange, the ground contact length at that time is set as a reference ground contact length, and a determination reference value is set on the basis of the reference ground contact length. As a result, the relative determination reference value corresponding to the tire type can be set, and a variation of the reduction rate of the tire air pressure when it is determined that the tire air pressure is reduced can be reduced. As a result, the reduction in the tire air pressure can be detected with high precision regardless of the tire type.

Abstract: A wheel assembly position identifying apparatus includes transmitters, each of which is provided in one of wheel assemblies and includes a transmission section and a control section, and a receiver, which includes a receiving section, a measuring section, and a wheel assembly position identifying section. The wheel assembly position identifying section is configured to detect, more than once, a rotational position of each wheel assembly at which the RSSI has an extreme value, for each position detecting signal received during one rotation of the wheel assembly, and identify the position of the wheel assembly in which the corresponding transmitter is provided based on variation of the rotational position of the wheel assembly at which the RSSI has the extreme value.

Abstract: A first tire pressure sensor module is configured to provide information related to a pressure of a tire of a vehicle and comprises a pressure sensor configured to determine the information related to the pressure of the tire. The pressure module further includes a controller configured to selectively operate the tire pressure sensor module in an active state and in an inactive state, wherein an energy consumption of the tire pressure sensor module is lower in the inactive state than in the active state. The controller is further configured to control an output of the information related to the pressure of the tire in the active state, and operate the tire pressure sensor module in the inactive state based on determining that information related to a velocity of the tire indicates a velocity above a threshold.
