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 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.

摘要： A vehicular driving assist system includes a sensor disposed at a vehicle and operable to capture sensor data. An electronic control unit (ECU) includes electronic circuitry and associated software, and the electronic circuitry includes a data processor for processing sensor data captured by the sensor. The vehicular driving assist system, via processing at the data processor of sensor data captured by the sensor, detects a tread of a tire of the vehicle. The vehicular driving assist system determines a tread depth of the tread of the tire. The vehicular driving assist system, responsive to the determined tread depth being below a threshold tread depth, generates a worn tire signal to alert a driver of the vehicle that that the determined tread depth is below the threshold tread depth.

摘要： A method performed by an electronic device to monitor one or more wheels of a vehicle. The method includes receiving first accelerometer measurements of a first accelerometer mounted on the vehicle's first wheel when the vehicle is moving during an interval of time, determining based on the first accelerometer measurements a first path followed by the first accelerometer when the vehicle is moving during the interval of time, receiving second accelerometer measurements of a second accelerometer mounted on a vehicle's second wheel when the vehicle is moving during the interval of time, determining, based on the second accelerometer measurements, a second path followed by the second accelerometer when the vehicle is moving during the interval of time, and determining based on a comparison of the first path with the second path that at least one of the vehicle's first wheel and the vehicle's second wheel is misaligned.

摘要： A device for measuring tread depth of tyres, wherein in use a tyre can be driven over the device in a first direction, the device comprising: a light source arranged to illuminate the tyre; an obstruction extending in a second direction substantially perpendicular to the first direction and arranged to partially block the light emitted from the light source such that a shadow is cast on the tyre when the tyre is located above the device, and such that the shadow is cast on the tyre in a direction substantially perpendicular to the tread of the tyre; and a camera arranged to view an illuminated section of the tyre.

摘要： 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.

摘要： Tire sensing systems operable to determine one or more physical characteristics of a tire include millimeter wave transmitting and receiving devices. A processor is communicatively coupled with a memory that includes instructions to transmit and receive a millimeter wave toward and from the tire. Memory also includes instructions to image first and second radial extents of the tire based on the received millimeter wave as well as instructions to determine a dimensional difference between the first and second radial extents of the tire. Vehicles including such tire sensing systems as well as non-transitory machine-readable storage mediums and methods are also included.

摘要： A tire wear measuring device that detects wear of a tire based on a magnetic field from a magnetic object embedded in the tire includes magnetic sensors and a battery. The battery is capable of transmitting the magnetic field from the magnetic object, and has an outer edge from which the magnetic field from the magnetic object is emitted as an emission magnetic field. Each of the magnetic sensors is disposed in a position where the emission magnetic field is detectable by the sensor.

摘要： A system for predicting tire lift-off propensity of a vehicle tire includes a vehicle tire-affixed tire-identification device for providing a tire-specific identification, multiple tire-affixed sensors mounted to the tire measuring tire-specific parameters and generating tire-specific parameter information, one or more vehicle-affixed sensor(s) mounted to the vehicle to measure vehicle speed and a lift-off propensity estimator generating a lift-off propensity for the vehicle tire from a database containing experimentally-derived, tire-ID specific, lift-off propensities correlated with measured tire-specific parameter information and vehicle speeds.
