摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A truck comprises a tractor and a trailer hitched thereto. At least one tire is mounted on each end of each of the tractor's axles and at least one tire is mounted on each end of each of the trailer's axles. A sensor is associated with each tire. Each sensor acquires tire-condition data about its respective tire and transmits this tire-condition data to a proctor. The proctor can coordinate realtime tire-condition displays, facilitate flagging of tire-condition problem tires in a fleet yard, and/or allows large data downloads for historical evaluation.

摘要： A direct tire data collection and communication device is adapted for use in a pneumatic vehicle tire. The device incorporates a tire-mounted electronics module comprising a microcontroller, and at least one tire property sensor in electronic communication with the microcontroller and capable of measuring at least one operational property of the vehicle tire. The threshold operational property value defines a positive tire safety condition and a negative tire safety condition. The electronics module calculates accumulated travel data of the vehicle tire while in the negative tire safety condition. A transmitter transmits the travel data to an electronic remote terminal.

摘要： A system and method for measuring, recording and reporting vehicle tire temperatures and/or pressures. In one aspect, a sensing device including a convex protective vessel, with pressure and/or temperature sensors enclosed therein. The sensing device is dropped freely within the interior of a tire prior to rim mounting. A movement sensor can also be included in the sensing device. The protective vessel, including all sensors, is not attached or connected in any way to the vehicle tire, rim, or valve stem such that the sensing device is independent of the vehicle tire, rim, and valve stem, and moves freely within the interior of the tire. A balancing set including a dummy device, substantially equal in weight to a sensing device, and means for connecting the dummy device to the sensing device at 180 degrees separation around the tire may also be employed.

摘要： An arrangement of a tire pressure sensor unit on the inner wall of the tread of a vehicle tire in a retaining device for the sensor unit is provided. The retaining device is connected to the inner wall, wherein a sealing compound is applied to the inner wall, or in the case of a retaining device having a closed bottom section which is connected to the inner wall, the sealing compound is applied to the bottom section facing the sensor unit. In the event that a foreign object punctures the inner wall, or punctures the inner wall and the bottom section, the sealing compound prevents at least a short-term loss of pressure caused by the hole resulting therefrom in that the sealing compound at least almost tightly seals the hole.
