Abstract
The present invention is a method for estimating the speed of a vehicle with antilock brake devices by obtaining a vehicle speed as a reference value for determining a slip ratio of a wheel based upon a wheel speed, an acceleration and a deceleration. At least the deceleration is based upon a differentiated value of a highest wheel speed from all wheels. In a vehicle in which the drive wheels are rigidly coupled, at least the deceleration is based upon a differentiated value of a highest value of the lowest wheel speed of the drive wheels and the wheel speeds of the driven wheels.
