Abstract
A method is disclosed for improving the estimate of vehicle yaw rate in the computer of the brake or traction control system of a vehicle, like a truck or sport utility vehicle, having a relatively high center of gravity and tending to roll during yaw. Yaw is typically estimated by sensing the speed of the non-driven wheels, determining the difference between the wheel velocities and dividing the difference by the track of the wheels. A table of correction factors correlated with vehicle speed is prepared and used to compensate for the effect of roll on yaw rate.
