Tire resonance frequency detecting system having inter-wheel noise elimination and method for the same |
摘要 |
Tire vibration frequency components of left-hand and right-hand tires are derived from wheel speed signals while a vehicle is traveling. A noise frequency component is detected based on a correlation between the vibration frequency components of the left-hand and right-hand tires, and the noise frequency component is reduced relative to the vibration frequency component. Thereafter, resonance frequencies of each tire are detected using the vibration frequency component from which the noise frequency component is reduced, and tire air pressures are detected on the basis of the resonance frequencies.
