PURPOSE: To improve the comfortableness during the traveling by correctly realizing the anti-roll control during the traveling on the road surface with low friction coefficient.

CONSTITUTION: A suspension control device is provided with a wheel speed sensor 18 for a right front wheel to detect the speed of the right front wheel, a wheel speed sensor 19 for a left front wheel to detect the speed of the left front wheel, a wheel speed sensor 20 for a right rear wheel to detect the speed of the right rear wheel, a wheel speed sensor 21 for a left rear wheel to detect the speed of the left rear wheel, a map for the low μ road surface corresponding to the road surface where the friction coefficient is low, and the memory storing the map for the high μ road surface corresponding to the road surface where the friction coefficient is high, and the difference between the rotational speed of the driving wheels and the rotational speed of the driven wheels is calculated based on the detected values by the respective wheel speed sensors 18-21. The suspension control device is also provided with a control part 24 to select the map for the low μ road surface from the memory where the number of the condition in which the difference in the rotational speeds becomes equal to or over the prescribed value reaches the prescribed number to be set in the specified period of time.
