Abstract: Disclosed herein is a method and device for carrying out an avoidance maneuver of a motor vehicle. An object in the surroundings of the motor vehicle which is on a collision course is detected. A warning is output to the vehicle driver, to the effect that the motor vehicle is on a collision course, and the steering activity of the vehicle driver is detected. An externally actuable rear-wheel steering device is subsequently switched such that the front wheels and the rear wheels of the motor vehicle are controlled in the same direction. Also, the vehicle movement dynamics effects of the actuation of the externally actuable rear-wheel steering device in the same direction are compensated. A further warning is output to the vehicle driver in order to cause the vehicle driver to perform a greater steering activity necessary as a result of the actuation of the externally actuable rear-wheel steering device.

Abstract: A driving dynamics control system for vehicles. The control system including at least one driving dynamics controller that is fed setpoint specifications and driving state variables as input data. The control system also includes a plurality of actuators that can be controlled and/or regulated to modify the dynamics of the vehicle, such as steering, adjustable independently of the driver, on a front and/or rear axle of the vehicle, a chassis adjustable independently of the driver, a brake adjustable independently of the driver, and a drive train adjustable independently of the driver. The driving dynamics controller determines a central control specification from the setpoint specifications and the driving state variables and sends it to a distribution algorithm that distributes the control specification into manipulated variables for driving the actuators.

Abstract: A device and method for the establishment of quality parameters of a digital map. A currently determined position of the vehicle and a measured value of an attribute of this position is used to calculate a quality parameter which serves as additional information for the data of the digital map. A driver assistance system constitutes an improved aid for a driver of a vehicle, since, in addition to the data of the digital map, the driver assistance system uses the feedback information of the quality parameter.

Abstract: A method for determining an optimal steering angle in understeer situations of a vehicle is described. To assist a driver in reliably stabilizing the vehicle during an understeer situation while driving, a model-based driving traction coefficient factor, a model-based kinematic factor, and a float angle are taken into account in the determination of a steering angle. A limited steering angle ?v,lim at which a maximum lateral force is set, is determined by addition of the driving traction coefficient factor, the kinematic factor, and the float angle. A system suitable for implementation of the method is also described.

Abstract: 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.

Abstract: Disclosed is a method of controlling the driving dynamics of a vehicle, in which a nominal value ({dot over (?)}ref) of a driving state variable that corresponds to a preset driver input is compared with a detected actual value ({dot over (?)}) 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 (?)}ref) of the driving state variable with the actual value ({dot over (?)}) 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.

Abstract: Currently available driving dynamics control systems such as ESP or TCS require in the driving dynamics limit range information about the actual maximum coefficient of friction between tires and roadway to function reliably. A proven approach is to use, once the control is active, the actual utilization of grip as the maximum coefficient of friction. The object of the invention relates to a method for determining the actual maximum coefficient of friction independently of the activation of the control. The method permanently determines values which are representative of the utilization of grip in longitudinal and/or lateral direction, based on measured and/or estimated variables that represent the actual longitudinal forces, lateral forces and vertical forces acting upon the individual wheels and tires, while using measured or calculated actual state variables representative of the tire slip angle and/or the tire slip angle velocity and/or the longitudinal slip and/or the longitudinal slip velocity.
