The invention concerns a device and a method for detecting a tire on a vehicle to determine whether there is a single or twin tire on an axle. The device has an optical sensor for this purpose, the sensor detecting at least one region of a rim on which a tire to be determined is mounted. An evaluation unit is also provided which is designed to determine a shape of the area of the rim from the sensor signals and to generate a signal from the shape which represents the type of tire.

The present invention relates to a machine for treating a tired wheel comprising a base (2), at least one column (3) which projects from the base (2), at least one tool-holder arm (4a, 4b, 4c) supported by the column (3) and at least one work tool (5a, 5b, 5c) supported by or articulated to the tool-holder arm (4a, 4b, 4c).

A method for inflating a tyre mounted on a corresponding wheel rim comprises the following steps in sequence; placing a tool at an operating position, where a first bead of the tyre is interposed between the tool and a second bead of the tyre, and one end of tool is positioned axially between a first flange of the rim and a first rib of the rim and positioned radially between an outside surface of the rim and a tread of the tyre; blowing a gas under pressure through an inflation valve of the tyre into a chamber delimited by the tyre and by the rim, with the tool at the operating position, so that the first sidewall of the tyre is pressed against the end of the tool; removing the tool from the operating position.

A tire state management system (10) is provided with an image data acquisition unit (210) for acquiring 1st image data acquired by imaging the outer surface at a first timing and second image data acquired by imaging the outer surface at a second timing later than the first timing, a damage portion acquisition unit (220) for acquiring a damage included in the 1st image data and a damage included in the 2nd image data, a vehicle operation information acquisition unit (230) for acquiring operation information of a vehicle on which a tire is mounted, and a maintenance prediction unit (240) for estimating a progress speed based on the damage included in the 1st image data and the progress speed included in the 2nd image data and predicting a maintenance timing for the tire based on the progress speed and the operation information.

A checking method and line for checking a tyre for vehicle wheels. The tyre is associated with a model associated with a setting for image acquisition devices. Once the model is obtained, preliminary images of the tyre are acquired, from which at least one adjustment value representative of at least one geometric characteristic of the tyre is obtained. A deviation between the at least one adjustment value and a respective reference value associated with the model is then calculated. The setting associated with the model of tyre is then adjusted based on the calculated deviation and the tyre is then inspected to look for possible production defects by acquiring images of at least part of the surface of the tyre using the image acquisition devices, set according to the adjusted setting.

Examples embodiments relate to techniques for automatic condition analysis of vehicle tires. A robotic device may initially obtain air pressure data corresponding to a vehicle tire from a first sensor and perform a first comparison between an air pressure level of the vehicle tire and a threshold air pressure level. Responsive to the air pressure level of the vehicle tire exceeding the threshold air pressure level, the robotic device may use a mechanical manipulator to rotate the vehicle tire and obtain sensor data representing an outer surface of the vehicle tire during rotation from a second sensor. The robotic device may then perform a second comparison between sensor data representing the outer surface of the vehicle tire and a model for the vehicle tire. The robotic device may then use the second comparison to generate a diagnostic output that represents a condition of the vehicle tire.

A tire management method with which specific information of a tire can be acquired at arbitrary timing in a manufacturing process of a vehicle is provided. The tire management method is a method of managing a tire group including a plurality of tires 1 on each of which a first mark M1 and a second mark M2 are provided on specific positions of a side surface, the method including: a step of associating, with respect to each of the tires included in the tire group, specific information of the tire and mark positional information (12, r1, and r2) related to positions of the marks M1 and M2, and recording these into a computer 2; a step of acquiring mark positional information of a tire selected from the tire group; and a step of acquiring, by using the computer 2, specific information associated with the previously-acquired mark positional information.

The invention relates to a method for determining at least one tyre-specific characteristic of a tyre (15) of a motor vehicle (1), in which an area of the tyre (15) of the motor vehicle (1) is captured by means of at least one vehicle-side camera (3, 6), wherein a tyre wall (16) of the tyre (15) with a tyre inscription (19) is captured as the area by means of the at least one camera (3, 6), and the tyre inscription (19) is identified by means of an evaluation device (13) and the at least one tyre-specific characteristic is determined on the basis of the tyre inscription (19). The invention also relates to a driver assistance system (2) and a motor vehicle (1).

Method for determining concentric mounting of a tire on a wheel. In one embodiment, method for determining concentric mounting of a tire on a wheel comprises: providing a tire including at least one bead area, wherein at least one rim centering tolerance indicator is oriented in the at least one bead area, and wherein the at least one rim centering tolerance indicator extends circumferentially about the tire; mounting the tire on a wheel to form a tire-wheel assembly, the wheel includes a circular cross-section including a center point; rotatably mounting the tire-wheel assembly on a tire balancing machine; providing a light source adjacent to the tire-wheel assembly, the light source projects a projected reference point upon the at least one bead area; rotating the tire-wheel assembly; and observing the runout of the projected reference point relative to the at least one rim centering tolerance indicator.

A tire inspection method includes: capturing a transmission image of a tire including a steel chafer at a bead portion; generating an image at an inspection device from the captured image of a full revolution of the tire with the steel chafer portions extracted using a spatial filter generated in accordance with an incline of the wires of the steel chafer; detecting a locus of a front side edge and a back side edge of the steel chafer; generating an image from the captured image with the steel chafer portions removed; detecting a locus of a turned-up edge of a carcass from this image; and determining at the inspection device the position of the carcass to be appropriate or not on the basis of the locus of the turned-up edge of the carcass.
