Abstract
In a tire state quantity detecting apparatus, a detector that deforms by force exerted from a tire and that outputs a signal corresponding to the quantity of deformation is embedded within the tire. The detector is enclosed in a capsule within the tire, so that the quantity of deformation of the detector is reduced relative to the quantity of deformation of the tire.
Claims21
A tire state quantity detecting apparatus provided in a tire for detecting a tire state quantity of the tire, comprising:
- a detector that is embedded in the tire, and that deforms by a force exerted from the tire, and that outputs a signal corresponding to a quantity of deformation of the detector;
- and
- a reduction mechanism that is disposed between the tire and the detector, and that dynamically reduces the quantity of deformation of the detector with respect to a quantity of deformation of the tire, wherein the tire state quantity is detected based on the output signal of the detector.
A method of detecting a tire state quantity of a tire, comprising the steps of:
- outputting a signal from a detector that is embedded in the tire, and that deforms by a force exerted from the tire, the signal corresponding to a quantity of deformation of the detector, wherein a reduction mechanism is disposed between the tire and the detector so as to reduce the quantity of deformation of the detector with respect to a quantity of deformation of the tire;
- determining the tire state quantity of the tire based upon the output signal;
- and
- outputting the result of the tire state quantity determining step.
