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 radar system having at least one radar transmission unit, at least one radar reception unit, a central unit, and a glass fiber for connecting these units, wherein the central unit has a central optical transmission unit to provide an optical radar driver signal, and wherein the at least one radar transmission unit has an optical reception unit and a radar transmitter, wherein the optical reception unit receives the optical radar driver signal and converts the optical radar driver signal into an electrical radar driver signal and provides the electrical radar driver signal for driving the radar transmitter, wherein the at least one radar reception unit includes a radar receiver, a mixer and an optical modulation unit. Also disclosed is an associated method.

摘要： A method for supplying power from at least one power supply unit to transportation vehicles requiring a power supply, in which a position of a transportation vehicle-side power supply interface of a transportation vehicle requiring power is determined for each transportation vehicle and the transportation vehicle-side power supply interface is automatically coupled to a power supply interface of the power supply unit by the power supply interface of the power supply unit being moved by a robot to the transportation vehicle-side power supply interface and coupled thereto. A robot is responsible for coupling transportation vehicles to a suitable power supply interface of the power supply unit.
