TIRE STATE DETECTION DEVICE AND TIRE STATE DETECTION METHOD |
摘要 |
<p>A tire state detection device capable of detecting a tire state with high accuracy. This tire state detection device (100) is a device for detecting the tire state of a pneumatic tire (200) affixed to a wheel and comprises a vibration input unit (110) for inputting predetermined vibration to the tire (200), a frequency information acquisition unit (120) for acquiring frequency information relating to the tire (200) when the predetermined vibration is inputted, and a tire state estimation unit (130) for extracting the resonance frequency and anti-resonance frequency of the tire (200) from the acquired frequency information and calculating, from the extracted resonance frequency and anti-resonance frequency of the tire (200), an outer moment of inertia and a spring constant when the tire (200) is modeled using the outer moment of inertia, an inner moment of inertia, and the spring constant of elastic force acting therebetween.</p> |
