DRIVING CONDITION ADAPTED TO THE STEERING ENGAGEMENT BASED ON VEHICLE DYNAMIC CONTROL

The invention relates to a device which is used to control the driving dynamics of a vehicle, comprising means which are used to detect at least one driving state variable which represents a driving state and comprising a vehicle dynamic control which is used to determine an additional steering angle, under the proviso that a steering movement can be carried out in addition to the steering movement commanded by the driver. The device is characterised in that the vehicle dynamic control (100, 110) comprises at least two control units (340, 350) which are associated with, respectively, a driving state range, such that they comprise a determining agent which is used to determine a current driving state, wherein the current driving state emerging form the driving state variable (h, F, Ey) can be determined, and that it comprises an activation agent (360) which is connected to the determining agent, which enables a control unit (340, 350) to be freely connected, which is associated with the ...

Driving dynamics control adapted to driving conditions and based on steering interventions

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.
