Abstract: 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.

Abstract: The present invention relates to a method and a control circuit for detecting and evaluating the conditions of vehicle movement dynamics for a motor vehicle by means of wheel force sensors, preferably tire sensors, which take the preadjusted air slot between at least one rotating encoder and at least one pick-up for measuring data into account as a standard for the transverse forces that act on the wheel or on the tire. In order to reduce the errors in the evaluation of wheel forces, especially of deformations of the wheel rim and/or the tire detected by means of tire sensors, the air-slot-dependent operating point of the output signal of the pick-up for measuring data or a signal-conditioning device is set irrespective of the preadjustment of the said point which was made during predetermined driving behavior.

Abstract: The present invention relates to a tire sensor, especially tire sidewall torsion sensor (=SWT sensor), including at least two pick-ups for measuring data being mounted at a distance from the tire rotational axis on the chassis, the said pick-ups for measuring data interacting with at least one encoder mounted on or in the tire wall or with at least one conventional encoder mounted on or in the tire wall and exhibiting poles, wherein the output signals or output information of such pick-ups for measuring data sensors are/is transmitted to the motor vehicle control system.

Abstract: A vehicle tire comprising a tread and a pair of sidewalls has a radially inner track and a radially outer track on a sidewall, each track being formed of a plurality of magnetically active sectors arranged in an angular serial manner to one another. Each sector is delimited from the next following sector by a respective sector transition and has a different magnetic property than the next following sector. A first group of the sector transitions have a radial extent forming a first angle relative to a radius of the tire and a second group of the sector transitions have a radial extent forming a second angle relative to a radius of the tire which is different than the first sector transition angle. Conclusions concerning the tangential tire deformation can be drawn from signals generated by magnetically sensing the phase shift of the magnetically active track sectors.
