Abstract

Detection means are provided which detect the rotational movements of the wheels, a variable which represents the steering angle, and at least one variable which represents the lateral movement and/or the yawing movement of the vehicle. Signals for influencing actuators for braking the wheels are formed by controller means as a function of the detected data in such a way that a control variable which is dependent on at least the detected lateral movement or yawing movement of the vehicle is adjusted to a desired range of control variables, that is to say the actuators are influenced in such a way that the control variable is kept within a desired range. This desired range is defined by two specific limit values.
