Abstract
A method and system for correcting an overestimated vehicle reference speed is presented. In one embodiment, speed, slip, and acceleration quantities are computed for at least one wheel of a vehicle. The speed, slip, and acceleration quantities are compared to selected speed, slip, and acceleration thresholds, respectively. A count is incremented if the quantities are consistent with at least one vehicle reference speed being overestimated. The existence of at least one overestimated vehicle reference speed is detected when the count attains a selected threshold. The vehicle reference speeds are modified when the overestimated vehicle reference speed is detected.
