INTEGRATED TREAD WEAR SENSOR AND TPMS CONTAINER FOR A TIRE
An integrated tread wear sensor and tire pressure monitoring system sensor unit container for a tire includes a tread wear sensor plug and a sensor container. The tread wear sensor plug includes a cylindrical projection extending through an opening formed in a selected tread element of the tire. A flange extends outwardly from the projection and includes a contact surface that is mounted to an innerliner of the tire. A conductive wire is disposed in the tread wear sensor plug and includes proximal ends disposed in the flange and a distal end disposed near a radially outer surface of the projection. The sensor container includes a wall extending radially from the flange of the tread wear sensor plug and terminating in a lip. A container cavity is defined by the flange, the wall, and the lip, and receives a tire pressure monitoring system sensor.
TIRE, TIRE WEAR DETECTION SYSTEM INCLUDING THE SAME, METHOD TO DETECT TIRE WEAR
A tire for a vehicle includes: a tread extending in a circumferential direction about a rotational axis of the tire; and wear indicators disposed in the tread and spaced apart from each other to be arranged in the circumferential direction. A harmonic noise signal caused by the tire when the tire rolls on a road surface to move the vehicle has neighboring first and second frequency peaks in a frequency spectrum of the harmonic noise signal, and the number of the wear indicators is in a range of 16 to 96 to generate, and when the tire rolls to move the vehicle at a speed in a target range, the wear indicators cause an additional frequency peak positioned between the first and second frequency peaks in the frequency spectrum when the tread is worn to reach a wear threshold.

METHOD FOR ESTIMATING THE STATE OF WEAR OF A TIRE
A method for estimating the state of wear of a tire comprises: recording a vibroacoustic signal (1001) produced by the tire running on a road during a time frame; converting the time signal (1001) into a frequency signal (1002) over a frequency range; segmenting the frequency range into frequency bands and associating a datum representing the frequency signal with each band, with the representative datum forming a variable of a matrix (1003); predicting a state of wear from the matrix, by means of machine learning (1004) from the data based on a learning database, according to modalities each representing a state of wear of the tire; and determining the state of wear of the tire (1005) after a number N of identical predictions in a series M of consecutive predictions.
MAGNETIC DRIVE OVER SYSTEM (DOS) PROVIDING TIRE TREAD THICKNESS/DEPTH MEASUREMENT
According to some embodiments disclosed herein, a system is provided to measure a tread of a tire. The system includes a nonmagnetic layer providing a drive over surface, a magnet, and a magnetic sensor associated with the magnet. The drive over surface is adapted to receive the tire thereon including the tread to be measured. The magnet has opposing first and second magnetic poles, the nonmagnetic layer is between the drive over surface and the magnet, and the magnet is arranged so that the first magnetic pole is between the second magnetic pole and the nonmagnetic layer. The nonmagnetic layer is between the drive over surface and the magnetic sensor, and the magnetic sensor is configured to detect a magnetic field resulting from the magnet and the tire on the drive over surface.
Tire with tread comprising an evolving tread pattern with sipes
A tire having a tread with a plurality of blocks 12 provided with at least one sipe 22 extending from the contact face of said block, and having a width that can vary in the direction of its depth, and known as a complex sipe. The tread has a first layer of material 38 and at least one second layer of material 40 radially on the inside of the first layer, the first layer being formed in a first rubber composition and the second layer being formed in a second rubber composition different from the first composition. The complex sipe 22 and the grooves separating the blocks are formed entirely in the first layer of material 38. Laterally on each side of the complex sipe, the second layer of material 40 extends, when viewed in transverse section in the block, beyond the bottom 30 of the complex sipe in the direction of the contact face of the block.
