The present device relates to a driving dynamics control system for vehicles, including at least one signal distribution to which vehicle data, environment data and data regarding the driver's request are sent in the form of input data, and including several controllable or regulatable subsystems which modify the dynamics of the vehicle such as a driver-independently adjustable steering system, a driver-independently adjustable chassis, a driver-independently adjustable brake, and a driver-independently adjustable driving track. The system is characterized in that the data of the signal distribution is sent to a central determining unit (driving condition detection, driver request detection), in that the central determining unit determines from the data of the signal distribution a central control target, and these items of data regarding the central control target are sent to a central regulating variable distribution or a central driving condition controller, respectively, which, in an interactive communication with the subsystems, actuates these subsystems in such a way that the control target is realized by the subsystems on the vehicle.

Driving dynamics control system for vehicles

Disclosed is a method for assisting an operator of a vehicle in adjusting a nominal steering angle at steerable wheels of the vehicle for the vehicle stabilization. An additional steering torque is applied to the steering line of the vehicle, which is determined dependent on a difference between a nominal steering angle and an instantaneous steering angle. The method is characterized in that a value of a load moment acting on the steering line of the vehicle is estimated, and that the additional steering torque is established dependent on the estimated value for the load moment.

When swaying motions of a trailer or semi-trailer of a car-trailer combination are encountered, input signals which are taken into consideration to calculate a reference signal frequently include also oscillation components, due to which driving dynamics control for stabilization of the car-trailer combination can become very unreliable. To enhance the reliability of driving dynamics control of this type, a method is disclosed in which an input signal (Y) is sensed that includes signal oscillations which are due to a swaying motion of the trailer or semi-trailer and are superimposed on a base component (Y) of the input signal (Y). A reference signal is calculated from the input signal (Y), in which case the calculation is executed in such a way that the reference signal by approximation corresponds to a reference signal which is determined from the base component (Y) of the input signal (Y). A correcting variable for influencing the driving behavior of the towing vehicle of the car-trailer combination is then determined depending on a deviation between the reference signal and a detected actual signal. Furthermore, the invention discloses a driving dynamics control system which is appropriate to implement the method.

Method and driving dynamics control system for stabilizing a car-trailer combination

A process for increasing the stability of a vehicle upon acceleration on a roadway with a non-homogenous coefficient of friction, whereby a drive wheel is acted on by a braking force on a side with a low coefficient of friction by means of a drive slip regulation. A value (p) is determined which corresponds to the braking force (F) set by the drive slip regulation (ASR). The value determined (p) is used for the determination of a disrupting yaw momentum (M), and a control portion (&#x394;&#x3b4;) of a supplemental steering angle (&#x394;&#x3b4;) is determined in dependence on the disrupting yaw momentum (M). An apparatus for the implementation of the process is also provided.

A method for controlling the driving dynamics of a vehicle provides that a steering movement is carried out on the basis of a set value, which is calculated as a function of a deviation between a desired value and an acquired actual value of a vehicle state variable. In this method, at least one membership degree of an acquired value of a steering angle, which is set by a driver, and/or of a steering angle gradient, which is set by the driver, in a predetermined fuzzy set, are/is determined, and a value of the set value is changed as a function of the membership degree.

A device for controlling the driving dynamics of a vehicle senses at least one driving condition variable being representative of a driving condition and has a driving dynamics controller for determining an additional steering angle, according to which a steering motion can be carried out in addition to the steering motion commanded by an operator. The driving dynamics controller () has at least two control units (), which are respectively associated with one driving condition range. It includes a determinator for determining a prevailing driving condition, in which the prevailing driving condition can be established based on the driving condition variable ({dot over (&#x3a8;)}, {dot over (&#x3b2;)}, a), and in that it includes an activation logic () being in connection with the determination means and being adapted to enable a control unit (), which is associated with the established driving condition range.

Method for controlling a brake pressure

In a method and a device for assisting an operator of a vehicle in the vehicle stabilization, an additional steering torque is applied to the steering line of the vehicle. The method manifests itself by the feature that a first component of the additional steering torque is determined depending on a steering angle difference between an instantaneous steering angle at steerable wheels of the vehicle and a nominal steering angle, and the steering angle difference is determined depending on a difference between an instantaneous value of a yaw rate of the vehicle and a value of a reference yaw rate, and with the value of the reference yaw rate being established in a vehicle model by way of a value of at least one variable predefined by the driver. The device implements the method.
