Abstract
An apparatus for calculating an estimated vehicle speed. The estimated vehicle speed is based upon the wheel speed of a wheel associated with a brake of the vehicle that has been applied, in order to obtain an estimated vehicle speed that closely approximates the true vehicle speed. The present invention is especially applicable to vehicles having an antilock control system, in that the antilock brake control can be more accurately controlled to be operated when the wheel speed of the vehicle exceeds a predetermined amount less than the true vehicle speed.
