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.

Modular vehicle dynamics control system

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.

Vehicle dynamics control system using control variable derived by means

A movement variable which represents the movement of a vehicle is controlled by actuating at least one actuator for applying a braking force to the wheels. Controller means use controller internal variables to form signals for influencing the actuators with the effect of adjusting a control variable. The controller means has a first area adapted to the respective selected sensor configuration in such a way that the controller-internal variables are formed on the basis of the sensor signals, and a second area for processing the controller-internal variables independently of the selection of the sensor configuration. As a result, simple adaptation with low development and application outlay to a wide variety of sensor configurations is possible.
