ABSTRACT:
A braking force acting on the wheel is actuated by a very small amount at a resonant frequency of a vibrating system comprised of a vehicle body, a wheel, and road surface, and the amplitude of the resonant-frequency component of the wheel speed is detected. A gain in the amplitude of the resonant-frequency component of the wheel speed with respect to the amplitude of the very small actuation of the braking force is determined. A mean braking force is controlled to decrease when the gain is smaller than a reference value, and to increase when the gain is greater than the reference value.
