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

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.
