摘要： Techniques for determining a condition of a component of a vehicle and/or adjusting a configuration of a vehicle based on a condition of a component of the vehicle are discussed herein. The vehicle can receive vehicle component data and use the vehicle component data to determine a condition of one or more vehicle components. The vehicle can use a sensor, such as an image sensor, to capture or otherwise determine the vehicle component data. The condition of the component(s) of the vehicle may be determined using a machine learned model trained to determine condition of the component from image data. The vehicle can determine vehicle configuration data based on the condition. The vehicle configuration data may include an instruction to navigate to a maintenance facility, to remove the vehicle from service, constraining operation of the vehicle, etc.

摘要： A tire inspection system includes a data acquisition unit, a groove depth determination unit, and an alert processing unit. The data acquisition unit acquires data for groove depth derived from measuring a groove depth of a tire mounted on a vehicle a plurality of times per groove by using the measurement instrument. The groove depth determination unit determines whether a per-groove difference in groove depth acquired by the data acquisition unit is equal to or larger than a predetermined value. When the groove depth determination unit determines that the difference is equal to or larger than the predetermined value, the alert processing unit outputs an alert to indicate that the groove depth should be measured again.

摘要： A contactless tire inspection apparatus for tire tread depth measurement using 3D reconstruction includes a driver side (DS) measurement device (MD) and a passenger side (PS) MD. The DS MD includes a DS light source configured to, responsive to receiving a trigger signal (TS), project a first structured illumination (SI) onto a DS tire of a vehicle and at least one DS camera configured to, responsive to receiving the TS, capture DS image(s) of the first SI projected onto the DS tire for 3D reconstruction. The PS MD includes a PS light source configured to, responsive to receiving the TS, project a second SI onto a PS tire of the vehicle and at least one PS camera configured to, responsive to receiving the TS, capture PS image(s) of the second SI projected onto the PS tire for 3D reconstruction when the at least one DS camera captures DS image(s).

摘要： A computer-implemented method enables vehicle tire wear prediction based on minimal input data points. Information is aggregated in a hierarchical data structure regarding historical tread values for multiple tires, and respective values associated with the historical tread values for each of multiple parameters that are hierarchically defined from highest to lowest levels. A current tire tread value is provided from a sensor associated with a first tire, and respective values associated with the current tire tread value are provided for each of the multiple hierarchically defined parameters. The current tire tread value is matched with information from the hierarchical data structure corresponding to matching values for one or more of the hierarchically defined parameters having at least a predetermined threshold number of available tread values, and a tire wear rate is predicted for the first tire based at least in part on the matched information from the hierarchical data structure.

摘要： Apparatus for applying noise-reducing elements to a tyre for vehicle wheels that has a radially inner surface with a service area and a circumferential dimension. The apparatus determines the position in circumferential direction of the service area, determines the position in circumferential direction of a target area on the radially inner surface of the tyre based on the position in circumferential direction of the service area, and applies a noise-reducing element the target area. The position in circumferential direction of the service area is determined by circumferentially inspecting the radially inner surface of the tyre starting from a reference position, detecting the angular position of the service area with respect to the reference position and determining the position in circumferential direction of the service area based on the angular position and on the circumferential dimension of the radially inner surface of the tyre.

摘要： Method and apparatus for checking tyres for vehicle wheels. A tyre to be checked is fed to a checking station. A sidewall of the tyre lies on a supporting portion of a rotating table. The supporting portion lies on a plane while the rotating table has a rotation axis perpendicular to the plane. A centring operation is carried out to align, in the plane, the rotation axis of the tyre with the rotation axis of the rotating table. The centring operation includes identification, in the plane, of the rotation axis of the tyre by: a) acquisition of an image of the tyre laid on the supporting portion of the rotating table; b) definition, in the acquired image, of a number of analysis directions intersecting at one selected central point; c) for each analysis direction: c1) definition, in the acquired image, of a number of potential axes of symmetry, perpendicular to the analysis direction; c2) calculation of a level of symmetry of the image with respect to each potential axis of symmetry, where the level of symmetry is indicative of the probability that the centre of the tyre is on the respective potential axis of symmetry; c3) determination of a probability distribution indicative of a variation of the level of symmetry along the analysis direction; d) determination of a centre of the tyre on the basis of a cumulative probability distribution obtained through a combination of the probability distributions calculated for the analysis directions; e) identification of the rotation axis of the tyre in an axis that passes through the determined centre and perpendicular to the plane.
