The slip of the automobile often arises in acceleration and in braking. As the result, the travel performance remarkably causes the adverse effect, since the grip force of the tire is lost. The driving force of automobiles is transmitted by a frictional force between tires and road surface. The frictional force is a function of the friction coefficient between tires and road surface and the weight of car-body. Due to a variation of this friction coefficient, the controlled object has an uncertainty. Hence, the drive-control of the automobiles with uncertain parameters is a very difficult problem. In this paper, we report the drive control system of automobiles by using sliding mode control theory which is a superior control method for uncertainty.
