The invention relates to a system and a method for automatically controlling a vehicle F in a traffic network, comprising a central unit which provides respective envelopes EHof a number I of flat geographical sub-regions TBof the traffic network, as well as an assigned attribute Kfor each of the geographical sub-regions TB, wherein the attribute Kindicates the intensity of a risk posed to the vehicle F itself and/or to objects arranged in the sub-region TBif the vehicle F should enter the respective geographical sub-region TB, the central unit and the vehicle F being designed and set up to communicate data, the vehicle F featuring: a first unit for determining the current position POSof the vehicle F in the traffic network, a second unit for determining the distance d(POS) of the vehicle F from the envelope EH* of the sub-region TB* closest to the position POS, and a third unit for carrying out automatic control interventions SEG in the longitudinal and/or transversal control or regulation process of the vehicle F, the automatic control interventions SEG being executed depending on the distance d(POS) and on the attribute K* assigned to the closest sub-region TB*.

System and method for automatically controlling a vehicle in a traffic network

A method and device for geo-referencing of supplied aerial image data, which has been recorded by an imaging system and in which a part of the earth's surface is imaged, wherein the geo-referencing of the aerial image data is carried out based on the supplied geo-referenced synthetic aperture radar (SAR) image data, in which the same part of the earth's surface is imaged, wherein the method and system include: determination of essentially point-like radar signatures RS in the geo-referenced SAR image data, provision of a position of the sun for recording time of the aerial image data and the part of the earth's surface imaged therein, determination of elongated cast shadows SS produced in a direction of solar radiation in the aerial image data based on the position of the sun at the time of recording, determination in the aerial image data of initial points AP facing the sun of the determined cast shadows SS, determination of spatially corresponding point-like radar signatures RS and the initial points AP of the cast shadows SS, registration of the aerial image data with the SAR image data based on the corresponding radar signatures RS and the initial points AP, and transfer of the geo-referencing of the SAR image data to the aerial image data registered with the SAR image data.

A lane keeping assistance system including position means for determining a first position of the vehicle in a network with a first accuracy; first interface for providing trajectory of the vehicle in the network; second interface for providing position data of right boundary objects and position data of left boundary objects, and radar signatures of these boundary objects; radar system to scan right and left lateral environments of the vehicle and determine distances to objects on a right of the vehicle and radar signatures thereof, and distances to objects on a left of the vehicle and radar signatures thereof; evaluation unit to perform identification of acquired objects based on the first position, the provided data, and the determined data, and to determine a second position of the vehicle with a second position accuracy; and control device to control the vehicle taking into consideration the target trajectory and the second position.

Lane keeping assistance system

Driver assistance system and method of assisting a driver when operating a vehicle in a transportation route network. The system includes a first interface to provide navigation data relating to the network, a position detection unit to provide a position of the vehicle, a second interface to provide first data relating to first objects, arranged along transportation routes of the network, a sensor system to sense current surroundings of the vehicle at the position in order to generate surroundings data, a first evaluation unit to determine second data relating to second objects based on the surroundings data, a fusion unit to match and fuse the first data and the second data to form third data, and a control unit to execute at least one assistance function in order to assist operation of the vehicle, wherein the assistance function is executed depending on the third data and the navigation data.

Driver assistance system

A device includes a first means for determining a first position of a vehicle, a second means for determining a movement direction of the vehicle, a third means for providing a number of fixed point data that specify, at least for significant radar objects on a planet surface, radar signature thereof and position thereof, a radar system for scanning a current surrounding area of the vehicle and detecting radar data, wherein, for a number of radar objects present in the surrounding area, radar signatures thereof and relative positions thereof in relation to the vehicle are determinable from the radar data, and wherein the radar system is configured to determine a second position, and the first means is configured such that the first position is correctable based on the second position and/or a warning is issuable if the first position and the second position differ by more than a predefined value.
