Abstract
An improved control method that utilizes active brake controls to provide vehicle control during conditions of carriage motion tendency about a longitudinal vehicle axis. Accordingly, the control may be integrated with known active brake controls that regulate yaw rate and/or slip angle or traction controls that regulate front wheel slippage, thereby significantly improving the functionality of the respective control for little or no additional cost. A measure of vehicle carriage motion tendency is determined by computing a control parameter based on the roll angle of the vehicle and the rate of change of roll angle. If the computed control parameter exceeds a first calibrated threshold, a condition of carriage motion tendency is detected and the active brake control actuators are activated to reduce the velocity of the front wheels of the vehicle by a delta velocity command determined as a function of the roll angle and roll angle rate. When the computed control parameter falls below a second calibrated threshold, the delta velocity command is gradually decayed to exit the control.
