Abstract
An estimation system includes: a first sensor that can be disposed between a wheel and a tire mounted on the wheel and outputs a first sensor signal in accordance with a pressing force applied by the wheel and the tire; and a processor that estimates a state of a rotating body including the wheel and the tire based on the first sensor signal. The processor generates a first section signal by dividing the first sensor signal by a specific section and estimates the state of the rotating body based on the first section signal.
Claims20
An estimation system comprising:
- a first sensor configured to be disposed between a wheel and a tire mounted on the wheel and to output a first sensor signal in accordance with a pressing force applied by the wheel and the tire;
- and
- a processor configured to;
- generate a first section signal by dividing the first sensor signal by a specific section;
- determine a damping ratio from the first section signal;
- and
- estimate a state of a rotating body including the wheel and the tire based on the damping ratio.
An estimation method comprising:
- acquiring a sensor signal in accordance with a pressing force applied by a wheel and a tire mounted on the wheel from a sensor disposed between the wheel and the tire;
- generating a section signal by dividing the sensor signal by a specific section;
- determining a damping ratio from the section signal;
- and
- estimating a state of a rotating body including the wheel and the tire based on the damping ratio.
A non-transitory computer-readable recording medium recording an estimation program, the estimation program configured to cause a computer to execute:
- acquiring a sensor signal in accordance with a pressing force applied by a wheel and a tire mounted on the wheel from a sensor disposed between the wheel and the tire;
- generating a section signal by dividing the sensor signal by a specific section;
- determining a damping ratio from the section signal;
- and
- estimating a state of a rotating body including the wheel and the tire based on the damping ratio.
