Abstract
An estimated vehicle speed computing device computes an estimated vehicle speed based on a computed non-drive wheel speed and a computed drive wheel speed of the vehicle. A first computed vehicle speed is computed based on the drive wheel speed and a second computed vehicle speed is computed based on the non-drive wheel speeds. When the first computed vehicle speed increase more than a predetermined level, the second computed vehicle speed is employed as the estimated vehicle speed. Furthermore, when the second computed vehicle speed is greater than the drive wheel speed, a speed other than the second computed vehicle speed is employed as the estimated vehicle speed.
