In the present invention, an estimated car body speed is obtained on the basis of the highest wheel speed selected from three wheel speeds including the lowest of the wheel speeds of left and right rear wheels and the wheel speeds of left and right front wheels. Because the car body speed is obtained on the basis of wheel speed selected by Select-High of three channels of wheel speeds of the two front wheels and wheel speed by Rear Select-Low, wheel speed of outer rear wheel, which is much higher than the speed of the gravity center of the car body when a car is turning, is excluded, and the estimated car body speed thus obtained is closer to the speed of the gravity center of the car body.
