Abstract
A sensor system for acquiring a perturbation, induced by a contact patch of a tire, in data generated by a sensor system mounted in the tire, comprises at least one sensor adapted for generating the data related to a physical property of the tire, and an acquisition system comprising memory. The sensor system is adapted for triggering the acquisition system to acquire the data and for storing it in a buffer in the memory, until a predefined delay after the perturbation is recognized. The perturbation is recognized by comparing the stored data with at least one characterizing feature of the perturbation.
Claims15
A sensor system mountable in a tire, the sensor system comprising at least one sensor adapted for generating the data related to a physical property of the tire, and an acquisition system comprising memory, wherein the sensor system is adapted for triggering the acquisition system to acquire the data and storing it in a buffer in the memory, wherein the sensor system is configured for acquiring a perturbation which is induced by a contact patch of a tire, in data generated by a sensor system mounted in the tire, and that the data is acquired and stored until a predefined delay after the perturbation is recognized, wherein the perturbation is recognized by comparing the stored data with at least one characterizing feature of the perturbation.
A method for acquiring data from a sensor mounted in a tire, the method comprising an acquisition cycle comprising:
- acquiring the data from the sensor;
- storing the data in a buffer;
- acquiring a perturbation, induced by a contact patch, in the data from the sensor by comparing the data in the buffer with at least one characterizing feature of the perturbation thereby obtaining a positive comparison result if the perturbation is present or a negative comparison result if the perturbation is not present;
- and
- repeating the steps of acquiring, storing, and comparing in case of a negative comparison result and before a predefined delay after the first positive comparison result.
