Method for detecting a tire module detached from the inner face of a tire for vehicles
First Claim
1. A method for detecting detachment of a tire module from an inner face of a tire of a multi-tire vehicle, comprising:
- measuring a centrifugal acceleration acting on a tire module of a tire to obtain acceleration values;
analyzing the acceleration values during an acceleration of the tire in at least one of a starting phase and at a constant low speed;
activating a warning signal of the detachment of the tire module from the inner face of the tire when a statistically significant standard deviation of the analyzed acceleration values is detected relative to acceleration values for not detached tire modules mounted to the inner faces of the other tires of the multi-tire vehicle; and
outputting the warning signal that the tire module is detached from the inner face of the tire.

Abstract
The invention relates to a method for monitoring and detecting the detachment of a tire module from the inner face of the tire, having the following steps: measuring the centrifugal acceleration on a tire module by an acceleration sensor arranged in the tire module; forwarding the measured acceleration values to an evaluation unit; analyzing the acceleration values upon acceleration of the vehicle in the starting phase or upon constant low speeds of the vehicle; activating a warning signal in the evaluation unit, insofar as the analysis of the acceleration values results in a statistically significant standard deviation in comparison to a not detached tire module from the inner face of another tire, thus detecting a freely tumbling tire module in the hollow space of the tire; outputting a warning signal indicating which tire module has detached from the inner face of the tire to the vehicle owner.
