摘要:
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 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 (pASR) is determined which corresponds to the braking force (FB,ASR) set by the drive slip regulation (ASR). The value determined (pASR) is used for the determination of a disrupting yaw momentum (MZ), and a control portion (ΔδZ) of a supplemental steering angle (Δδ) is determined in dependence on the disrupting yaw momentum (MZ). An apparatus for the implementation of the process is also provided.

摘要:
In a method and apparatus for stabilizing running of a wobbling trailer towed by a vehicle, a tandem of trailer and vehicle is braked by a brake device activated by a control device. The braking process is triggered, when an amplitude of the oscillation of the trailer exceeds a predetermined value. As a result, the tandem is decelerated to a speed at which the amplitude of the oscillation of the trailer falls below a predetermined value. The tandem is decelerated more intensely in the case of a wobbling trailer and when travelling at a first travelling speed than in the case of a wobbling trailer and when travelling at a second travelling speed which is lower than the first travelling speed, and the tandem is braked in presence of the first driving speed during exceeding a lower value of the amplitude than in the presence of the second driving speed.

摘要:
The invention relates to a method in which the driving stability of a vehicle is controlled, wherein a yaw rate difference is influenced by an additional yaw moment which is generated at least partially by building up braking torque independently of the driver at one or more wheels. According to the invention, the braking torque which influences the additional yaw moment is variably apportioned between the front axle and the rear axle of the vehicle in an oversteering situation.

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 (100, 110) has at least two control units (340, 350), 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 (Ψ)}, {dot over (β)}, ay), and in that it includes an activation logic (360) being in connection with the determination means and being adapted to enable a control unit (340, 350), which is associated with the established driving condition range.

摘要:
Disclosed is a method of controlling the driving dynamics of a vehicle, in which a nominal value ({dot over (ψ)}ref) of a driving state variable that corresponds to a preset driver input is compared with a detected actual value ({dot over (ψ)}) of the driving state variable, and in which a rolling moment distribution is detected and modified. The method is implemented in such a manner that the driving performance of the vehicle is determined by comparing the nominal value ({dot over (ψ)}ref) of the driving state variable with the actual value ({dot over (ψ)}) of the driving state variable. Also, depending on the determined driving performance, a new rolling moment distribution is determined which corresponds to a predefined driving performance and the new rolling moment distribution is adjusted.
