Abstract
An apparatus for attenuating wheel speed variation during periods of brake intervention traction control is provided. The speed of the or each driven wheel is monitored and the braking force applied to the or each driven wheel is controlled in accordance with the wheel speed and wheel acceleration. Braking force may be increased when a rate of change of wheel acceleration is increasing and the wheel is accelerating (i.e. between periods B and C of FIG. 5c); whereas braking force may be decreased when the rate of change of wheel acceleration is decreasing and the wheel is decelerating (i.e. between periods D and E of FIG. 5c).
