ABSTRACT:
An improved method of estimating a vehicle speed reference value (VREF) at a wheel so as to prevent false slip detection and premature ABS activation in a motor vehicle equipped with an Anti-Locking Braking System. A maximum possible rate of change of velocity (ACCEL limit) for the vehicle is determined over a predetermined range of corresponding vehicle speeds. Wheel speed and estimated reference speed at the wheel (VREF) are determined along with the rate of change of the wheel speed (WHEEL ACCEL). The WHEEL ACCEL is compared to the corresponding ACCEL limit to limit the estimated reference speed to the corresponding ACCEL limit.
