ABSTRACT:
A device for estimating reference wheel speed of each wheel of a vehicle having: a calculator for calculating slip angle of vehicle body based upon lateral acceleration, yaw rate, and vehicle speed; an estimator for estimating speed of vehicle body at its center of gravity based upon wheel speed and yaw rate; and a calculator for calculating the reference wheel speed of each of the front left, front right, rear left and rear right wheels based upon the vehicle body gravity center speed, steering angle, slip angle of vehicle body, yaw rate, a half track of a corresponding wheel, and a half wheel base of a corresponding wheel as follows:
