Abstract

The movement of a vehicle is controlled by actuating actuators which apply a braking force to the wheels. For this purpose, the rotational speeds of the wheels, the steering angle and at least one of the lateral acceleration and the yawing movement of the vehicle are detected. A first module is configured so that the actuators are actuated by means of the actuation signals with the effect of controlling a first variable. The second module is configured so that signals for influencing the actuation signals are formed with the effect of controlling a second control variable. In order to obtain this second control variable, at least the variable which represents the steering angle is processed. The second controller component brings about a control of a variable which is determined at least as a function of the lateral movement or the yawing movement of the vehicle.
