Abstract
Official abstract text for this publication.
Disclosed herein is a method of setting valid output sections of a 3-axis acceleration sensor mounted within a tire of a vehicle, including setting an output signal of the 3-axis acceleration sensor in the z-axis direction as a reference signal, setting a specific section of the output signal in the z-axis direction as a valid section where a part of the tire where the 3-axis acceleration sensor is mounted contacts a road surface, and setting sections of output signals of the 3-axis acceleration sensor in the x-axis and y-axis directions corresponding to the valid section in the z-axis direction as valid sections in the x-axis and y-axis directions. The method sets precise valid sections applied to detect information between the tire and a ground surface so as to minimize a component of a noise section by connecting output signals in the x-axis, y-axis and z-axis directions.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of setting valid output sections of a 3-axis acceleration sensor mounted within a tire of a vehicle to measure accelerations in x-axis, y-axis and z-axis directions, comprising: setting an output signal of the 3-axis acceleration sensor in the z-axis direction as a reference signal, wherein the z-axis direction is perpendicular to a road surface; setting a specific section of the output signal in the z-axis direction as a valid section where a par…
