Abstract
In a vehicle anti-lock brake controller, a differential slip between the wheels on each side of an axle is sensed to detect a yaw condition and the wheel with the lower slip value is identified as the high coefficient wheel. In response to a detected yaw condition, the monitored value of slip of the high coefficient wheel is controlled about a target slip value that has an initial value less than the critical slip value at the beginning of antilock controlled braking to minimize longitudinal force imbalance and which is thereafter ramped to the critical slip value to maximize longitudinal braking forces.
