摘要： A method for acquiring information in the spatial environment of a vehicle, comprising: providing at least two radar sensors arranged at different positions at the vehicle; transmitting radar signals by the radar sensors, the radar signals being assigned to the radar sensors; receiving reflected components of the radar signals assigned to the radar sensors at the respective radar sensors and further processing these reflected components of the radar signals as reception information; assigning time information to the reception information obtained from the respective radar sensors, the time information forming a time reference for the reception information; assigning location information to the reception information obtained from the respective radar sensors, the location information forming a location reference for the reception information; and processing the reception information obtained from the at least two radar sensors into common environment information by taking into account the time information and the location information.

摘要： A method for classification of ground conditions in the vicinity of a vehicle using a radar sensor, comprising: receiving reflected portions of a radar signal at a receiver unit of a radar system; calculating information derived from the received portions of the radar signal for discrete spatial regions by the radar system or a control unit connected thereto; assigning the information to data structure units associated with a geographical location and the assignment of the information taking into account movement of the vehicle; collecting pieces of information in the respective data structure units, the pieces of information being obtained from reflected portions of radar signals transmitted at different times; evaluating the information contained in the data structure using a classifier to obtain information regarding the ground condition; assigning ground condition types to the data structure units based on evaluation results obtained by the classifier.

摘要： A method for automatically controlling a following vehicle. A leading vehicle is guided along an actual trajectory, and a desired trajectory is produced for the following vehicle. The actual trajectory of the leading vehicle is captured by the following vehicle, and a trajectory similarity is determined by comparing the captured actual trajectory of the leading vehicle and the produced desired trajectory of the following vehicle. Automatic control of the following vehicle along the desired trajectory is activated if the trajectory similarity exceeds a particular value. Also disclosed is a system for automatically controlling a following vehicle using a leading vehicle.

摘要： A method and system for automatically controlling at least one following vehicle, where a scout trajectory is produced for a scout vehicle and the scout vehicle is guided along the scout trajectory. Scout environmental data are captured by scout sensors and a desired trajectory is produced for the following vehicle. Following vehicle environmental data are captured by following vehicle sensors. Reference trajectory data are produced based on the scout trajectory and reference environmental data are produced based on the scout environmental data. The reference trajectory data and the reference environmental data are transmitted to the following vehicle. A trajectory similarity is determined by a trajectory comparison of the desired trajectory produced and the transmitted reference trajectory data, an environment similarity is determined by an environmental data comparison of the captured following vehicle environmental data and the transmitted reference environmental data.

摘要： A method for determining a quality of a surface in the surroundings of a transportation vehicle, wherein three-dimensional surface coordinates of the surface are generated using a sensor assembly. In the method, an approximation of the course of the curvature of the surface in at least one direction is obtained based on the surface coordinates and the surface coordinates are classified to characterize the quality of the surface using the course of the curvature and/or vertical distances of the approximation of the course of the curvature from the three-dimensional surface coordinates. A device for carrying out the method.

摘要： A device displaying information about an imminent takeover of manual control of a vehicle. The device includes a radio receiving apparatus and a controller, and a projection unit, a vibration unit or a display. The radio receiving apparatus receives the information by radio. The projection unit projects the information by lighting of the projection unit, while the vibration unit is activated by the device in accordance with the receipt of the information. The information is displayed on the display together with additional information.

摘要： A method and a device for a vehicle configured for automatic longitudinal guidance. The method involves detecting a guide vehicle, the guide vehicle being a vehicle travelling directly in front of the vehicle; determining a current state from at least two states which describe a current reaction of the vehicle to the guide vehicle; and displaying the current state in animated form on a display.

A desired trajectory is produced for the following vehicle and following vehicle environmental data are captured by following vehicle sensors. A scout trajectory similarity is determined based on the scout trajectory produced and the captured actual trajectory, reference trajectory data are produced and reference environmental data are produced based on the scout environmental data. The reference trajectory data and the reference environmental data are transmitted to the following vehicle and a trajectory similarity is determined by a trajectory comparison based on the desired trajectory produced and the transmitted reference trajectory data.
