A system and method for detecting changes in tire status in real time, e.g., changes in tire pressure or changes that might indicate an imminent tread separation or other failure, using magnetic sidewall torsion (SWT) signatures for tires. A measured magnetic signature of a tire is compared to a stored magnetic signature that describes the tire in an undamaged state or otherwise acceptable state. If the measured magnetic signature deviates too much from the stored signature, or if a change in tire pressure is detected, the system and method can further provide an associated warning to the driver and/or provide an input to a vehicle control system, which would automatically take action to correct or at least mitigate the effects of the failing tire, e.g., by decelerating the vehicle.

Tire status detection system and method

A method for monitoring an operating condition of a vehicular tire. The method includes providing magnetized areas in the tire and magnetic field sensors on the chassis of the vehicle. Rotation of the tire produces magnetic field pattern signatures which characterize the tire's materials, construction and deformation conditions. Changes in magnetic field pattern signatures from a baseline are indicative of impending abnormalities in tire integrity that can be recognized in advance to forestall vehicle accidents attributed to tire faults.

Tire status detection system

The invention is directed to a transmitting and/or receiving unit for building into an elastic structure. The transmitting and receiving unit includes one or more electronic circuits or circuit elements and, if needed, sensors and/or signal elements assigned thereto. The transmitting and/or receiving unit has one or several antennas connected to the electronic circuit. The antenna includes one or several filaments which are so arranged in the surface or in space that the main directions of the stresses and forces, which occur within the surrounding elastic structure/matrix, essentially intersect or cross the filament axes.

Transmitting and/or receiving unit for incorporation into an elastic structure

System and method for ascertaining the emergency running condition of a pneumatic tire on a motor vehicle. The system includes at least one sensor device arranged at least on each axle. The at least one sensor device is adapted to supply a permanently present first periodic oscillation proportional to a wheel rotation speed as a speed output signal. The at least one sensor device includes one of an active and a passive magnetic field sensor being mounted to one of rotate with the tire and be stationary. The transmitter device is arranged complementary to the at least one passive and active magnetic field sensor and is adapted to produce a periodic magnetic field change in proportion to the wheel rotation speed in a detection range. At least one signal processing device is used for processing and evaluating the speed output signal. A transmission and a display device are used for at least one of the transmission and the display of the speed output signal, and for one of the transmission and the display of at least one of the output control and the warning signal. An emergency running device is arranged on the vehicle wheel.

A pneumatic tire is provided that has a way to provide information. The pneumatic tire has at least at one predetermined location a rubber mixture that is permeated with magnetizable particles that are magnetized in a number of first zones and differently or not at all in a number of second zones. The tire can be used in a slip regulation system, and apparatus for producing such a tire are also provided.

A vehicle tire has a plurality of first marks arranged in a circular pattern on a radially outer area of the vehicle tire. A plurality of second marks is arranged in a circular pattern on a radially inner area of the sidewall. Passing of the first and second marks is detectable by magnetic or inductive sensors. The derived signals are used to determine the longitudinal force acting on the tire or the tire spring travel or the footprint length or the load/pressure ratio during rotation of the tire.

A vehicle tire for a motor vehicle has a carcass, a belt, and tire tread. A device for generating data for determining tire-road adhesion or friction between the footprint of the vehicle tire and the road surface is provided. The device includes at least one magnetic sensor connected to a evaluation device. The at least one magnetic sensor has individual magnetic sensor elements forming cooperating sensor element pairs. The device also includes a magnetic field arranged in the belt and generated during tire manufacture by partial magnetization of the belt. The at least one magnetic sensor is arranged in at least one lug of the tire tread.

A device for measuring a rotary frequency of a rotating vehicle tire includes a number of first poles uniformly arranged on a circle with a radius R1 on or within a vehicle tire. A first sensor, for sensing the first poles, is stationarily arranged at a distance R2 from a rotational axis of the vehicle wheel. The radii have the following relationship: 0.9 R1&lt;R2&lt;1.1 R1. A computing unit is connected to the first sensor. The first sensor sends first signals to the computing unit when the first poles pass the first sensor. The computing unit determines a first time period between passing of sequential ones of the first poles. The computing unit multiplies a reciprocal value of the first time period by a reciprocal value of the number of the first poles to a multiplication product and supplies the multiplication product as a measure of a first rotary frequency to a user device.
