A method is provided for operating an active chassis system, in which wheels of at least one axle are arranged with a toe-in angle, and actuating elements which interact with supporting assemblies which are arranged between the wheels and a vehicle body. Wheel contact forces of the wheels assume different values as a result of the actuating elements being actuated. A side force is generated at the wheels which have a toe-in angle, and a resulting yaw moment is produced. A desired yaw rate is determined based upon information from a device which is arranged in the vehicle in order to determine the profile of the roadway in a control unit, and the wheel contact forces are set as a function of the desired yaw rate.

The opening of vehicle doors often leads to collisions with stationary obstacles that are not visible to the occupants or with moving obstacles that approach the vehicle without being noticed. Thus to avoid collisions when vehicle doors are opened, the aim of the invention is to take any modifications to the environmental situation of the vehicle as a result of a movement of the vehicle and the detected objects into consideration. This allows a collision of the vehicle doors with the objects to be reliably avoided. To achieve this, in a first step the probable trajectory of a vehicle is determined. In an additional step, the objects in the vicinity of the vehicle are detected and probable trajectories of said detected objects are determined. Respective probability ranges are then defined both for the vehicle and the pivoting zone of the vehicle doors and for the detected objects. The probability ranges of the pivoting zones of the vehicle doors are respectively compared with the individual probability ranges of the objects, in order to determine whether they overlap. If an overlap is identified, a response; signal that indicates the risk of a collision is generated.

The invention relates to a method of detecting objects within a wide range of a road vehicle. According to said method, the distance between a moving or stationary vehicle and one or more objects is calculated by distance-based image segmentation using stereoscopic image processing techniques and the properties of the detected objects are determined by object recognition in the segmented image areas. Image areas of three-dimensional and/or flat objects are detected and said three-dimensional and/or flat objects are detected by clustering 3D pixels according to defined criteria. Three-dimensional objects are determined by features with similar distance values and flat objects by features with similar height values.

A vehicle guidance system for assisting a driving lane change includes an object detection unit for detecting objects in a laterally adjacent rearward side space area of the vehicle. An analysis unit receives signals from the object detection unit and determines whether an object is situated in a dead angle section (blind spot) of the monitored rearward side space, or whether any such object in a section of the monitored rearward side space which is rearward beyond a dead angle section is moving forward at a higher speed than the system vehicle. If so, and if, in addition, it detects at the same time a lane change request pertaining to the corresponding side area, it activates a warning indicating unit for emitting a warning signal. According to the invention, a position detection device is provided which determines path data of the obstacle vehicle and the road geometry data, as well as the position of the system vehicle on the road. When the object detection unit detects an obstacle vehicle which is following in the rearward side space, corresponding to the covered distance recorded by the position detection device and the road geometry, a position assignment of the vehicle which is following is determined relative to the road.
