The invention relates to a method for regulating the driving dynamics of a vehicle during which a set value (?ref) of a diving state variable, said set value corresponding to a driver input, is compared with a recorded actual value (?) of the driving state variable, and during which a rolling moment distribution is detected and modified. The method is carried out such that: a. a vehicle handling of the vehicle is determined based on the comparison of the set value (?ref) of the driving state variable with the actual value (?) of the driving state value; b. according to the determined vehicle handling, a new rolling moment distribution is determined that corresponds to a predetermined vehicle handling, and; c. the new rolling moment distribution is set. The invention also relates to a device for regulating the driving dynamics of a vehicle comprising means for supporting rolling moments on the front and rear axle of the vehicle and comprising sensors for recording at least one driving state variable (?) for the vehicle that is suited for carrying out the method. The device can be advantageously used in a yawing moment compensating system (ESP).

The invention relates to a method for regulating the driving dynamics of a vehicle, according to which at least one wheel of the vehicle is impinged upon by a specific torque as a result of a clutch being controlled that transmits torque to the wheel and/or as a result of a differential being controlled that distributes torque to said wheel and at least one additional wheel. Said method is characterized in that a torque value is determined in accordance with a first and a second yawing moment value. The first yawing moment value is determined in the form of a yawing moment value generating a set point yaw rate value based on a vehicle reference model while the second yawing moment value is determined according to the deviation between the set point yaw rate value and a detected real yaw rate value as well as according to a deviation between a set point value and a real value of an additional driving state variable that differs from the yaw rate. The invention further relates to a device that is suitable for carrying out said method.

The invention relates to a device for stabilising a vehicle, in particular after a collision against a lateral carriageway boundary, comprising a lane recognition system (1), with which information relating to the course of the lane (K act ) is determined or detected, a collision detection unit, which identifies a collision (T crash ) of the vehicle, in particular against the lateral lane carriageway boundary, on the basis of signals from at least one sensor or on the basis of a driving state variable (ay, ax, V veh ), determines an, in particular electrically controllable, steering actuator for steering a steering system, and an, in particular electrically controllable, brake actuator for controlling one or more wheel brakes, a target path determination unit, which determines a target path (K ref ) for the vehicle, on the basis of the course of the lane determined or detected before or at the time of the collision, and a controller (2), which causes a guiding of the vehicle onto the target path and/or a stabilisation of the vehicle via a steering intervention, in particular a control of the steering actuator, and/or using individual wheel brake interventions, in particular a control of the brake actuator, and a method for stabilising the vehicle.

The invention relates to a method for improving the driving stability of a motor vehicle, wherein driver-independent braking interventions are triggered when a critical driving situation is expected on the basis of route information and current position data of the motor vehicle. The invention also relates to a corresponding system. According to the invention, the driver specifies information on the friction coefficient to be maximally used via a human-machine interface, said friction coefficient being used as the basis for the prediction of a critical driving situation.

The application relates to a device and a method for increasing the safety of a motor vehicle. A first sensor unit (2) senses the surroundings, in particular in order to detect free spaces and objects (0), and the position and movement thereof. A second sensor unit (20) senses the state of the surroundings, a third sensor unit (30) senses the state of the vehicle, and a fourth sensor unit (40) senses the driver's commands. The data are merged and a driving safety coordinator (6) determines at least one reliable driving corridor (K1, K2, K3, K4 to Kn) predictively and situationally in order to determine the operational safety. The driver's command can be limited to the driving corridor (K1, K2, K3, K4 to Kn) by means of components (9) which can be actuated actively and/or the motor vehicle (1) can be kept in the driving corridor (K1, K2, K3, K4 to Kn) by means of the components (9) which can be actuated actively.

The invention relates to a method for controlling the locking degree of an electronically controllable differential lock in a driven axle of a vehicle. The inventive method is characterised in that it checks whether a driving wheel on the driven axle is braked in a controlled manner by means of a driving dynamics regulator, and a zero locking degree in the differential lock is set, if it is established that a driving wheel on the driven axle is braked in a controlled manner by means of the driving dynamics regulator. Advantageously, if the vehicle is oversteered without any braking intervention by the driving dynamics regulator, a locking degree different to zero is generated. The invention also relates to a device for carrying out the method.

The invention relates to a method for carrying out an avoidance manoeuvre of a motor vehicle. In a first method step, an object in the surroundings of the motor vehicle, with which the motor vehicle is on a collision course, is detected. A warning is then output to the driver of the vehicle to the effect that the motor vehicle is on a collision course, and the steering activity of the driver of the vehicle is detected. An externally actuable rear-wheel steering device is subsequently switched in such a way that the front wheels and the rear wheels of the motor vehicle are steered in the same direction. Furthermore, the invention relates to a device for carrying out an avoidance manoeuvre. So that the driver of the vehicle continues to be able to control an avoidance manoeuvre with front and rear wheels which are steered in the same direction, the invention provides that the vehicle movement dynamic effects of the externally actuable rear-wheel steering device which is actuated in the same direction are compensated. For this purpose, a further warning is output to the driver of the vehicle in order to prompt the driver of the vehicle to carry out a greater degree of steering activity which is necessary as a result of the externally actuable rear-wheel steering device being actuated in the same direction.

The invention relates to a method for assisting a vehicle server in order to stabilise the vehicle consisting in supplying the vehicle steering cable with an additional steering moment. The inventive method is characterised in that the first part of an additional steering moment is determined according to a steering angle difference between the momentary steering angle on the steerable wheels of the vehicle and a reference steering angle, the steering angle difference is determined according to the difference between the momentary value of a sheer rate of the vehicle and the reference sheer rate value and the reference sheer rate value is determined by means of the value of at least one quantity which is predetermined by a driver on a vehicle model.
