Abstract
Vibration observed in a tire wheel portion exhibits a resonant vibration phenomenon in which vibration fluctuates between a wheel and a surface of a tire. This phenomenon shows different characteristics depending upon how the surface of the tire is in contact with a road surface. Here, a detector derives a parameter corresponding to a gradient of a coefficient of friction based on these characteristics and detects a brake condition. Also, a controller executes ABS control based on such parameter.
