acquiring (step E1), from a tangential acceleration signal of said monitoring module, measurements of a variable in the group comprising a maximum tangential acceleration peak and a minimum tangential acceleration peak,
performing (step E2) processing of said measurements of said acquired variable,
comparing (step E3) said processed measurements to a predetermined maximum variation threshold value,
transmitting a warning (step E4) when said predetermined maximum variation threshold value is reached.
The invention also relates to a tire pressure monitoring module for implementing said method.-

摘要： A tire deterioration inferring (estimating) method uses a tire deterioration inferring device placed on the inner surface of a tire. The method has: a deformation velocity measurement step of measuring a tire deformation velocity, which is the deformation velocity of the tire while the tire is rotating, and obtaining time-series changes in the tire deformation velocity; a calculation step of calculating peak values of the tire deformation velocity from the time-series changes in the tire deformation velocity; and an inference step of inferring the degree of the deterioration of the tire by using a first peak value, which is a peak value of the tire deformation velocity before and at the stepping of the tire or at and after the kicking of the tire, the first peak value being in the time-series changes in the tire deformation velocity.

摘要： A vehicle monitoring system includes a controller and one or more wheel-integrated monitoring devices that are each disposed between a wheel of a vehicle and a tire that is mounted to that wheel. The wheel-integrated monitoring device has multiple sensors, a transceiver, and a power unit. The sensors generate different measurements during each rotation of the wheel. The transceiver wirelessly transmits the different measurements to the controller. The power unit provides power to the sensors and the transceiver. The controller analyzes the measurements and generates alerts on a dashboard or console in response to the measurements revealing wheel alignment, tire tread, and/or other driving characteristics that differ from manufacturer specifications by more than a threshold amount or that present safety hazards to the driver.

摘要： A system and method are provided for estimating and applying vehicle tire traction. Vehicle data (e.g., movement and location-based data) and tire sensor data are collected at a vehicle and transmitted to a remote computing system (e.g., cloud server). A wear status is determined, and traction characteristics determined for at least one tire, based at least on the vehicle data and the determined tire wear status. The predicted tire traction characteristics are transmitted from the remote computing system to an active safety unit associated with the vehicle, or a fleet management system, wherein the recipient is configured to modify vehicle operation settings based on at least the predicted tire traction characteristics. A maximum speed for the vehicle may be defined by the recipient, or a minimum following distance where, e.g., the vehicle is one of multiple vehicles in a defined platoon.

摘要： A vehicle includes a first wheel, a second wheel, and a controller. The first and second of wheels have first and second tires, respectively. The controller is programmed to receive inputs indicative of tire tread wear of the first and second wheels. The controller is further programmed to, in response to a command to adjust torques of the first and second wheels to first and second desired torque values, respectively, and a difference between a tire tread wear of the first wheel and a tire tread wear of the second wheel exceeding a threshold, adjust the torque of the first electric machine to less than the first desired torque value and adjust the torque of the second electric machine to greater than the second desired torque value.

摘要： A tire maintenance support apparatus includes: a tire information acquisition unit, a replacement time calculation unit, and a replacement count calculation unit. The tire information acquisition unit acquires prediction data for groove depth of a tire mounted on each of a plurality of vehicles operated and managed. The replacement time calculation unit calculates a time of replacement of each tire based on the prediction data for groove depth acquired by the tire information acquisition unit. The replacement count calculation unit calculates the number of tire replacements in each period of time by tallying times of replacement calculated by the replacement time calculation unit for each period of time.

摘要： A system for monitoring tire tread on a vehicle may include front wheels, rear wheels, a sensor network to determine rolling radius data associated with the front wheels and the rear wheels, processing circuitry which may include a memory unit and may be configured to receive the rolling radius data from the sensor network, and a user interface which may display information to an operator of the vehicle. The processing circuitry may be further configured to determine a rolling radius of the front wheels and the rear wheels, determine a difference in the rolling radius between the front wheels and the rear wheels, compare the difference in the rolling radius to a predetermined threshold value, and generate a notification via the user interface to indicate that a tire rotation may be recommended responsive to the difference in the rolling radius exceeding the predetermined threshold value.
